2. BASIC SAFETY RULES
2.1. SAFETY WARNINGS
•The national and local provisions should be met.
•The equipment should be installed in compliance with
the legal standards applicable in the given location, re-
gion or country.
•The equipment should be used by persons (including
children) with impaired physical, sensory, mental ca-
pabilities and by persons without experience and re-
quired knowledge provided that such operation is not
carried out under their supervision or after proper in-
struction by a person responsible for their safety.
•You should always observe the guidelines given in the
operating manual to ensure the correct use of the
equipment and to prevent accidents.
•Operation and adjustment should be carried out by
adults. Errors and incorrect settings can cause hazard-
ous situations and/or incorrect operation.
•Prior to any operations the user (or any person oper-
ating the equipment) should read and understand the
whole contents of this manual.
•Equipment should be used only as intended. Each
other use is considered as misuse and hazardous as
a consequence.
•The equipment should not be used as a ladder or ob-
ject to lean against.
•Prior to installation, you should make sure that the
substrate will resist the force of the fireplace insert
considering its weight.
•In the case of disturbances in operation, the equip-
ment can be restarted only when the occurred problem
has been removed and the equipment is brought back
to its original condition.
•The user is fully responsible for misuse of the product
and relieves DEFRO from any civil and criminal liabil-
ity.
•All types of modifications or replacement of equipment
parts with non-original components or without authori-
zation may present a risk for the operator and relieves
DEFRO from any civil and criminal liability.
•Incorrect installation or maintenance (incompatible
with the contents of this manual), can cause injuries to
people, animals or property damage. Then DEFRO
shall be relieved of any civil or criminal liability.
•Part of the fireplace insert surface is very hot (doors,
handle, window panel, flue gas discharge pipe, etc.).
You should avoid direct contact with such components
without suitable protective clothing or protective equip-
ment such as e.g. heat-resistant gloves.
•Do not touch the window panel after heating up of the
fireplace insert.
•Keep children away from the equipment when it is op-
erating because each hot surface can cause burns.
•It is forbidden to use fireplace insert when glass is
cracked.
•Do not place and dry the underwear on the equipment.
Possible dryers for hanging underwear or similar
should be located at an adequate distance from the
equipment - fire hazard.
•It is absolutely forbidden to open the doors if the flue
is on fire. Then call the appropriate services.
•It is recommended to keep a distance 400 mm be-
tween hot parts of the fireplace insert and medium in-
flammable materials; otherwise use commercially
available insulation materials. Apply this hint also for

6 | Page
furniture, curtains etc. The minimum distances are
given in point 5.2 of the operating manual.
•It is absolutely forbidden to use flammable liquid for
equipment firing up.
•If the substrate, on which the equipment is located, is
made of inflammable materials, such as parquet or
floor lining then you should place a protective plate un-
der it (the plate should protrude 250-300 mm from the
front of the equipment).
2.2. WARNINGS RELATED TO OPERATION
•Equipment should be shutdown in the case of failure
or incorrect operation.
•Fuel used in the fireplace insert should meet the con-
ditions described in this manual.
•Internal parts of the fireplace insert should not be
washed with water.
•Avoid contact with water; above all do not wash any
painted surfaces until they are fully cured. The coating
on new devices is not an anti-corrosion coating; heat-
resistant paint achieves its protective properties only
after curing under the influence of heat (after several
ignitions).
•Do not expose the body to the action of hot air for a
long period of time. Do not heat excessively the room
where you are staying and where the equipment is in-
stalled. It may have an adverse impact on physical
condition and be a reason for health problems.
•Equipment should be installed in the rooms with fire
protection and equipped with all required components
such as supply (with air) and flue gas discharge.
•Fireplace insert and cladding made of ceramics should
be stored in rooms free from moisture and they cannot
be exposed to adverse effects of the weather.
•It is not recommended to place the body of the fire-
place insert directly on the floor and if such floor is
made of inflammable materials it should be properly
insulated.
•To facilitate possible interventions by the technical
personnel you should not place the fireplace insert in-
side the closed rooms and just by the walls which can
also disturb air intake.
•Always make sure and check whether the doors of the
combustion chamber are tightly closed when the
equipment is operating.
•Equipment consumes the exact amount of air that is
required for the combustion process; it is recom-
mended to connect the iron stove to air intake from
outside using a suitable pipe and through a special
outlet located at the back of the equipment.
ADDITIONAL INFORMATION
•You should contact the sales outlet or qualified per-
sonnel authorized by DEFRO in the case of any prob-
lems. Request original spare parts if the repair is nec-
essary.
•Use only fuel with properties compatible with the rec-
ommendations of this operating manual.
•Check and clean flue gas discharge ducts (connecting
piece to flue) periodically.
•Store this manual carefully because it should be avail-
able for a whole period of equipment operation. In the
case of selling or giving the equipment to the other
user you should always make sure whether the prod-
uct has the manual enclosed.
•Request a new copy from an authorized sales outlet in
the DEFRO company if it has been lost.
3. INTENDED USE
The DEFRO HOME RIVE fireplace insert as a furnace with manual
fuel charge is intended for enclosing or installation into a recess. Hous-
ing should not be permanently bonded with the insert, you should have
an option to disassemble it.
The DEFRO HOME RIVA fireplace insert is intended for the com-
bustion of hardwood e.g. beech, hornbeam, oak, acacia, maple, birch
etc. with moisture content below 20%. It is intended for heating of
houses and spaces where it is installed. It can be also used as an ad-
ditional source of thermal power.
The DEFRO HOME RIVA fireplace insert is equipped with a water
system intended for supplying of central heating system. It can operate
as only or additional source of supply for the CO system.
The DEFRO HOME RIVA fireplace insert with a water
system can be operated only after connection to the
central heating system and filling with water. Only then
proper heat discharge is ensured. Operation of the
equipment without water and outside the CO system re-
sults in loss of warranty.
4. TECHNICAL SPECIFICATION
4.1. DESIGN
Body (1, picture 1) of the DEFRO HOME RIVA fireplace insert is a
steel jacket, with a combustion chamber located inside (2). Floor cre-
ating chamber for air intake is a basis for the insert. The rear wall and
side walls of the combustion chamber are lined with claddings made of
concrete insulating refractory. The front wall of the combustion cham-
ber is restricted by a steel door (3) with a heat-resistant window panel
(4) and lock (5).
Fuel is combusted on a cast-iron grate (8) installed on the base.
Ash-pan container (9) is located under the grate. Deflector (15) is lo-
cated over the combustion chamber. It directs flue gas flow and im-
proves the degree of heat exchange.
Air necessary for the combustion process is supplied through an
air intake socket (10) equipped with an adjustment mechanism (11).
The air intake is located in floor of the fireplace insert. Openings for the
flue gas afterburning system (14) are additionally located in the rear
wall of the furnace chamber.
The steel water system is installed on top of the fireplace body. The top
plate of the system is equipped with connecting sockets for the pipe
supplying the central heating system (20), control (17) and supply (18)
for protecting the heat exchanger, temperature sensor (19) and socket
for vent (21). The Left and right wall of the system is equipped also with
connecting sockets for the return pipe (22) from the central heating sys-
tem. Flue gases are removed to the chimney through a flue located in
the upper wall of the water system.

4.4. FUEL PARAMETERS
A fireplace insert is intended for the combustion of wood from de-
ciduous trees (oak, hornbeam, ash, beech) with moisture content be-
low 20% (wood seasoned in proper conditions for at least 2 years). The
maximum length of chunks is given in table 1 It is allowed to use wood
briquet.
It is not allowed to use wet wood (extensive contamination of fire-
place and soot emission and decrease of furnace energy efficiency).
It is forbidden to use all other fuels, min. coal, softwood from conif-
erous trees, wood from tropical trees and any liquid fuels.
It is forbidden to combust all types of litter and wood wastes. Firing
with inadmissible materials in the fireplace may result in damage to the
fireplace and life and health hazard to the users (toxic flue gas from
chemicals).
Use of bad quality fuel or incompatible with the above-
mentioned recommendations would cause irregulari-
ties in the operation of the equipment and can lead to
loss of warranty and decline of the liability for the prod-
uct.
The fireplace is not a furnace intended for the combus-
tion of wastes and forbidden fuels cannot be com-
busted in it.
Wood should be seasoned minimum of two (2) years.
Firing with wet wood, with low calorific value, de-
creases the efficiency and has an adverse influence on
dry stove lifetime.
It is not recommended to use softwood and resinous
woods as fuel. It causes intensive smoke concentration
and the necessity to clean the equipment and flue more
often.
It is forbidden to combust coal, wood from tropical
trees, chemical products, liquid fuels etc., e.g. oil, alco-
hol, petrol, naphthaline, laminated, impregnated boards
etc., paper, cardboards, old clothes, wastes.
It is forbidden to exceed the recommended amount of
charged fuel, because it may cause overheating of the
equipment.
DEFRO R. Dziubeła sp.k. does not accept liability for
damages caused or improper burning of fuel if the fuel
used is prohibited.

5. TRANSPORT AND INSTALLATION
5.1. TRANSPORT AND STORAGE
The fireplace is delivered on a pallet, foil-wrapped and is fully as-
sembled. It is recommended to transport the fireplace insert, in such
packing condition, as close as the possible target location for installa-
tion, what will minimize the possibility of damage to the device housing.
All remaining parts of the packing should be removed in such a
way that it will not pose any hazard to people and animals.
The fireplace is to be transported in a vertical position!
Appropriate lifts are to be used for lifting and lowering the fireplace
insert. For transport, the fireplace insert is to be secured against mov-
ing and tilting on a vehicle's platform by means of belts, wedges and
wooden blocks.
A fireplace insert is to be stored in a non-heated room, under a roof
and with efficient ventilation.
Before the installation, you should check the completeness of the
delivery, its condition and remove all transport protections!
In a version with lifted doors (G versions) it is obligatory to check
the arrangement of ropes with carabiners to ensure that they are led
vertically on both sides of the unit, do not catch on the other compo-
nents and do not jam the mechanism.
Before the first lifting of the doors in the G version fire-
places, you should absolutely remove the transport
protections!
Failure to observe the above recommendation may
cause problems in the operation of the guillotine mech-
anism and even lead to its damage. DEFRO R. Dziubeła
sp.k. shall not be liable for any damages resulting from
failure to observe the recommendation.
5.2. WORKING ENVIRONMENT
DEFRO HOME RIVA fireplace insert should be installed
in compliance with the requirements of the currently ap-
plicable standards and legal regulations and the de-
tailed regulations of the target country. In Polan.d these
conditions are regulated by the Regulation of the Minis-
ter of Infrastructure of 12 April 2002 on technical condi-
tions which should be fulfilled by buildings and its lo-
cation. (Journal of Laws no. 75 of 2002 item 690 as
amended) and Polish Standard PN-EN 13229:2002 Inset
appliances including open fires fired by solid fuels. Re-
quirements and tests.
Fireplace insert should be installed in a suitable location allowing
opening of the doors and carrying out regular maintenance works. The
environment should be:
•adapted to operating conditions,
•equipped with a power supply 230V/50Hz,
•equipped with a suitable flue gas exhaust system,
•equipped with an external ventilation system,
•equipped with an earthing system with the CE certificate.
The design of the system should allow assembly and disassembly
without damaging the system and the insert.
The correct setting of the insert is necessary to obtain a satisfac-
tory heating level of the residential unit. Prior to assembly, it is neces-
sary to select a suitable position for stove installation. Check minimum
safe distances from materials susceptible to heat or inflammable ma-
terials such as load-bearing walls and other walls or wooden compo-
nents, furniture etc. Exemplary installation of a fireplace insert is pre-
sented in picture Picture .
Installation of the fireplace insert should observe the following
safety rules:

12 | Page
•minimum distance of 80 mm on the side and rear of the
equipment body from the non-flammable materials.
•minimum distance 200 mm from the side and rear of the me-
dium inflammable materials,
•minimum distance 800 mm from the front wall, where the me-
dium inflammable materials cannot be located.
•objects made of highly inflammable materials should be lo-
cated at a distance minimum of 2000 mm from the furnace.
If it is not possible to maintain the above-indicated distances then
you should apply process and building measures to avoid fire hazards.
In the case of contact with a wooden wall or wall made of other inflam-
mable material, it is appropriate to insulate the flue gas discharge pipe.
In the case of the floor made of inflammable materials,
it is appropriate to prepare a plane protecting the floor
and execute protection in accordance with the stand-
ards applicable in the given country.
Picture 13. Exemplary installation of fireplace insert.
ATTENTION!!!
Lack of expansion joint may be a reason for equipment damage.
Installation of the fireplace inconsistently with the minimum dis-
tances from the system results in loss of warranty!!!
The fireplace insert should be located on a substrate with a suita-
ble load-bearing capacity. In accordance with the Polish Standards
each square meter of the floor slab in the single-family building should
transfer the load of 150 kg. If this condition is fulfilled the fireplace insert
manufactured by DEFRO can be installed without needing to reinforce
the floor slab.
Nonetheless, if you are not sure about the design of floor slab,
where the fireplace insert is to be installed, you should absolutely con-
tact the building designer to reinforce the floor slab or execute a special
structure distributing the weight on a larger area.
The flooring in the room, where the stove is to be in-
stalled, should be properly dimensioned, to maintain
the load.
To ensure the correct operation of the fireplace insert you should
ensure the suitable inflow of air required for combustion (it is appropri-
ate to ensure approx. 40 m3/h) in accordance with the installation
standards and standards applicable in the given country. The volume
of the surrounding environment should not be less than 30 m3. You
should assume that the combustion of 1 kg of wood requires ~8 m3of
air.
If several inserts are to be used in one room the air de-
mand should be met for each insert.
Insert housing should ensure access of air necessary for ventila-
tion, air circulation in the housing. In the bottom part of the installation
(under the insert) it is appropriate to ensure air supply openings ensur-
ing air supply for combustion. To ensure the correct discharge of hot
air from the hood you should install exhaust openings ended with ven-
tilation grilles. These openings should be made in a way ensuring that
they cannot be plugged. They should be ended with grilles.
It is required to keep the expansion joint around the door frame of
the fireplace, that is minimum distance not lower than 5 mm. During the
designing of the system, it is required to consider also possible assem-
bly of a frame (which is an optional component), to ensure that after its
assembly the minimum expansion joint between the frame and the sys-
tem will be kept.
It is indicated to use a bigger expansion joint for the fireplaces with
lifted doors (G version), in particular between the front of the body and
the installation (it should be from 20 to 30 mm). It will contribute to the
longer and trouble-free operation of the door mechanism.
The active area of the grille should be selected correspondingly to
the power of the insert. It is assumed that it should equal 40 - 60 cm2
per 1 kW of power of the insert. Recommended active surfaces:
•fireplace insert power to 10 kW - grille cross-section min. 500
cm2,
•fireplace insert power to 15 kW - grille cross-section min. 700
cm2,
•fireplace insert power over 15 kW - grille cross-section min.
800-1200 cm2 and more.
Air can be supplied from adjacent rooms, provided that they are
equipped with external air supply and they are not intended for a bed-
room and bathroom, and where fire hazard is not present, for example:
garages, woodsheds, inflammable materials storage. You should ab-
solutely observe the recommendations of the applicable standards.
The temperature over the insert, inside the hood, is very high.
Therefore it is necessary to install a decompression relief plate inside
the hood, at a distance ~40cm from the ceiling of the room. It prevents
heating of the ceiling in the room, and heat losses and forces the in-
stallation of exhaust grilles below it emitting the heat from the relief
chamber over the insert. Relief grilles are installed alternately on both
sides of the housing - below and over the relief plate.
Installation of the fireplace insert should allow access to the outlet
of the flue for periodic inspection and cleaning.
Before installation of the fireplace insert with lifted
doors (G versions) you should check the correctness of
operation of the lifting mechanism and in particular, you
should check the arrangement of ropes with carabiners.

5.3. HOT AIR DISTRIBUTION SYSTEM
5.3.1. GRAVITY SYSTEM FOR HOT AIR DISTRIBUTION
The DEFRO HOME RIVA fireplace insert gives back approx. half
of the power to the environment when the air is being heated. In the
case of heating of small areas, e.g. room where the fireplace insert is
installed, and adjacent rooms, you should select a gravity system for
air distribution, when the hot air will raise upwards to the chamber in
heating ducts by way of thermal lifting forces.
Using the gravity system you should use properly insulated and
short (not exceeding 3 m) distributing ducts. For this system, it is not
recommended to distribute hot air to too many rooms. Also, use of too
long pipes (over 3 m from the flue) increases resistance and decreases
air flow velocity what causes that gravity flow is not effective.
5.3.2. FORCED SYSTEM FOR HOT AIR DISTRIBUTION
Picture 14. Hot air distribution system.
The application of the forced system for hot air distribution (DGP)
requires the installation of air supply device (turbine). It sucks hot air
heated by the fireplace insert and forces it to all branches of the system.
In such a case you should use a pipe connecting the flue with the air
supply unit with the biggest possible cross-section and the smallest
possible length
Installation of the DGP system should be entrusted to a
specialized company, which will check heat demand for
the given area and will correctly design the connection
system and arrangement of the individual parts.
5.4. CONNECTION TO EXTERNAL AIR INTAKE
Room, where the fireplace insert is installed, should be equipped
with the inflow of air in the minimum amount required for the correct
combustion process and for room ventilation. This can be done by ex-
ecuting fixed vents in the wall directed to the outside or through inde-
pendent or common ventilation ducts.
The external wall near the stove should have a through opening,
protected with a grille on the internal and external side, for this purpose.
Furthermore, the air intake should be:
•directly connected with the room, where the fireplace insert
is to be installed,
•protected with grille, metal net or suitable cover not restrict-
ing minimum cross-section,
•located in a way preventing plugging it,
•located with consideration of proper distances preventing
swirling of air (e.g. with respect to the windows).
Picture 15. Connection of fireplace insert to the external air intake.
5.5. INSTALLATION TO THE FLUE
The fireplace insert should be connected to the individual flue. The
size of the chimney draught should equal:
•minimum draught −6 ± 1 Pa,
•medium, recommended draught − 12 ± 2 Pa.
•maximum draught - 15 ± 2 Pa.
Prior to the permanent installation of the fireplace insert you should
make sure whether a condition of recommended draught is met. If the
draught is too small then you should disassemble a steel deflector of a
flue gas outlet (part 23 in figure 1) and re-check whether the condition
of recommended draught is met.
During the execution of opening for flue gas discharge pipe, you
should consider the possible occurrence of inflammable materials. If
the opening will pass through the wooden wall or wall made of material
sensitive to heat then you should obligatorily maintain the minimum dis-
tance from flammable material (value given on the certification label of
the pipe), with possible additional insulation using proper materials
(thickness 1.3 - 5 cm, heat conductivity min. 0.07 W/m °K).
Picture 16. Connection of fireplace insert to the flue.
As an alternative it is recommended to use insulated industrial
pipe, which can be also used outdoors, to avoid the occurrence of con-
densate.

For correct operation connector between the fireplace insert and
flue or smoke duct should be executed acc. to the below recommenda-
tions:
•horizontal sections should have a minimum slope of 3% to-
wards the top,
•length of the horizontal section should be minimum and
should not exceed 2/3 meter,
•a number of changes of directions, inclusive of the use of
the “T” component, should not exceed 4.
A chimney or individual smoke duct should meet the following require-
ments:
•be resistant to combustion products, water-proof and suitably
insulated, in compliance with conditions of use,
•be made of materials resistant to normal mechanical
stresses, heat, the action of combustion products and possi-
ble condensate,
•be vertical with the change of axis direction not exceeding
45°,
•be adequately separated with void space or suitable insula-
tion from combusted and inflammable materials,
•have preferably circular internal cross-section: square or rec-
tangular cross-section should have rounded corners with a
radius not smaller than 20 mm,
•internal cross-section should be constant, free and independ-
ent,
•have a rectangular cross-section with the maximum ratio be-
tween two sides equal to 1.5.
It is forbidden to use mechanical exhaust ventilation
when the insert is not connected to an external air inlet.
The fireplace insert should not be used if the chimney
draught is too low.
If the chimney draught is too low you should disassem-
ble the steel deflector on flue gas outlet.
Installation to flue should ensure access for cleaning of
the connector and the whole chimney system should be
equipped with proper inspection openings closed with
tight doors.
5.6. INSTALLATION IN CENTRAL HEATING SYSTEM
The DEFRO HOME RIVA fireplace insert is equipped with a water
system allowing operation in the central heating system. The water sys-
tem, located on top of the fireplace body, is equipped with a protecting
heat exchanger (cooling coil), so it is possible to install it both in an
open and closed system.
The connection of the chimney’s water system should be made in
compliance with the applicable standards and regulations and in par-
ticular with the following documents:
•The Regulation of the Minister of Infrastructure of 12
March 2009 on technical conditions which should be
fulfilled by buildings and their location.
•Standard PN-EN 12828:2014 - Heating systems in
buildings - Designing of water central heating systems;
The central heating system is to meet requirements
specified by the Polish Standard PN-91/B-02413 on the
protection of open system water heating devices and
pressure vessels.
In case of installation of the fireplace insert in a country
other than Poland, it is obligatory to apply relevant re-
quirements and standards of this country.
Before installation of the fireplace insert you should make a test
connection of water system to the central heating system and then en-
ter the working pressure in the system to check its tightness. A fireplace
insert should be embedded when all leaks in the water systems have
been excluded.
Pictures Picture and Picture present connection diagrams for the
water system of the DEFRO HOME RIVA fireplace insert in the heating
system.
The water system in the DEFRO HOME RIVA fireplace insert is
equipped with two supply and two return sockets so it is possible to
select hook up points to the central heating system. For correct and
effective operation of the water system locations for connection to the
central heating system should be in the cross-arrangement, that is left
supply socket and right return or right supply socket and left return.
Thermal protection of the outflow (10) is a valve, which based on
the temperature signal from the sensor (11) will be opened if the safe
operating temperature of the water system will be exceeded. Water
from the water system flowing through the heat exchanger cools the
water system down decreasing water temperature from the central
heating system and then it is discharged to the sewage system.

•Protecting heat exchanger (protecting coil pipe)
should be connected to the water supply system
ensuring continuous water inflow, also if the elec-
tric power is not available.
•Protecting heat exchanger is intended only for
emergency heat collection and should not be used
as a flow, utility water heater.
To ensure the correct operation of the water system it is necessary
to meet the condition that the temperature of the water returning from
the CO system is not lower than 50 °C (dew point for wood with mois-
ture content 20%). This is connected with steam condensation on cold
walls of the fireplace insert (so-called insert's sweating), which leads to
a decrease in lifetime and heating efficiency. This phenomenon can be
avoided by applying various methods, e.g. by setting higher tempera-
ture of water in the water system and adjustment of temperatures in
heated rooms using thermostatic valves or using mixing systems. The
function of thermal protection against a drop of return water tempera-
ture below the dew point is implemented by a mixing three-way ther-
mostatic valve (4), which based on the measured value of the installed
temperature sensor opens a corresponding valve with hot water mixing
it with cold water from return - in case of examples on the pictures 17
and 18.Picture Picture
It is required to install thermal protection in the system
preventing the return of water with temperature below
the dew point (50 °C). Lack of such protection leads to
a dramatic decrease of heating efficiency and damage
to the equipment. Failure to observe this recommenda-
tion may cause loss of the warranty.
It is required to install a safety valve (12) in the closed system. Its
task is to protect water system and installation against exceeding of
maximum allowable working pressure. The valve should be factory set
to 2.0 bar and should prevent exceeding of maximum operating pres-
sure by not more than 10%.
The valve should be installed as close to a heat source as possible:
it can be installed directly in a free supply socket or on a pipe supplying
the installation, in an easily accessible location.
If the allowable pressure is exceeded the safety valve discharges
excess of water and steam through the discharge pipe decreasing
pressure in the system. Therefore, you should ensure safe water and
steam outflow from a safety valve (e.g. to the sewage system).
It is recommended to use safety fittings, a so-called
safety unit, which consists of a safety valve, manometer
and vent.
Connections of the water system with the central heating system
should be made using threaded or flanged joints.
•Installation of the water system of fireplace insert
by welding results in loss of warranty!!!
•Fireplace insert installation should be carried out
by a person or company with suitable qualifica-
tions and authorizations.
•It is in the user’s interest to look after that instal-
lation is made in accordance with the regulations
in force and that installing company gives a war-
ranty for correctness and good quality of work-
manship which should be confirmed by a stamp
and sign on the warranty card of the stove.
•Hydraulic system of the water system of fireplace
insert should be made in compliance with the cur-
rently applicable standards and regulations. All
national and local provisions should be met!
6. USAGE AND OPERATION
6.1. FILLING WATER SYSTEM WITH WATER
Make sure that the central heating (CO) system is correctly filled
with water, which should be clean, clear and without any admixtures
prior to start up. Filling a water system with water should be carried out
only when it has been cooled down.
Water quality has an essential influence on the life of the water
system and the whole central heating system Water should have the
following parameters:
•pH reaction:
o8.0 ÷ 9.5 - in steel and cast iron systems;
o8.0 ÷9.0 –made of copper and mixed materials
steel/copper;
o8.0 ÷ 8.5 - for systems with aluminum radiators;
•total hardness < 20 °f,
•free oxygen content <0.1 mg/l, recommended <0.05mg/l,
•chlorides content <60mg/l.
Before connecting the fireplace with the water system
to the old central heating system user should carry out
flushing to remove sludge remaining in the radiators
and pipes.
Fill the system with water prior to firing up of the fireplace. Filling
with water should be carried out through the return socket of the water
system or installed fixture for filling and discharging (8, picture Picture
). This process should be carried out slowly in order to deaerate the
system.
To check if the system has been filled with water, the straight-run
valve located on the signaling pipe should be opened for a few sec-
onds. Continuous water outflow means the system has been filled in
correctly. Any water refills should take place in the boiler's inactivity
period.
•It is unacceptable and strictly forbidden to refill
water during fireplace insert's operation, espe-
cially when the temperature is high as it may lead
to its damage or crack.
•Water can be refilled only due to its losses by
evaporation. Other decrements such as system
leakage are inadmissible as they may lead to the
creation of boiler scale resulting in permanent
damage to the water system.
6.2. INTRODUCTORY REMARKS
Prior to installation of the fireplace insert you should make several
test fire ups. During test firing up you should check the operation of the
chimney damper and the other mechanical systems of the equipment.
During the initial period after installation, the fireplace insert should
be operated with power equal to approx. 30% of rated power and in-
crease temperature gradually. It allows gradual removal of internal
stresses preventing the occurrence of thermal shocks. Furthermore,
such a method of operation improves the durability of the insert.
The fireplace insert is subject to expansion and shrinkage during
the warming and cooling down stage what may cause slight squeaks.
This is an absolutely normal phenomenon because the structure of the
fireplace is made of rolled steel and this phenomenon shall not be con-
sidered as a defect.
Do not stay near the stove during several first fire ups. It is also
required to vent the room. Smoke, the odor of paint, silicone and other
materials used for the execution of the installation will disappear after
several fire ups. However, we remind you that they are not harmful to
health.
It is good practice to ensure efficient ventilation during
the first firing-up because small amounts of smoke and

16 | Page
odor or paint and other materials will be emitted from
the fireplace insert.
Do not use a non-installed fireplace insert. Test firing
up is an exception.
6.3. FIRST START-UP AND OPERATION
Before first start-up it is obligatory to seal the equipment
in accordance with the enclosed manual.
Firing from the top is a recommended method of the firing of the
fireplaces. Prior firing up you should set a slider of air inflow adjustment
to maximum opening (marking on the handle, presented in picture 19).
Then, open the doors of the fireplace insert and place fuel on the grate
as follows: place split thick chunks at the bottom, then another layer of
thinner chunks. Place small slivers at the top, where you may addition-
ally place eco-friendly kindling.
It is important to ensure free space (approx. 1 cm) between each
of the chunks.
The single fuel charge is given in table 1.
It is forbidden to use other materials than described
in this manual for firing up, in particular flammable
chemicals such as: oil, petrol, solvents and others.
Maximum closing maximum opening
Picture 19. Setting of slider for air inflow adjustment
If the draught in the chimney is not sufficient then you may unseal
it by the minimum opening of the fireplace doors during the initial firing
up stage. If the fireplace insert is not supplied with the air from outside
then it is required to supply a sufficient amount of the air by opening a
window in the room where the equipment is located.
You should use only hardwood (recommended beech, oak, horn-
beam, birch), preferably debarked, of low moisture content (below
20%).
During combustion, the doors should be opened only when the fuel
is being added. Recharging should be made only when only an ignition
layer, in the form of glow, remains in the furnace. Before adding the
wood, it is required to spread the remaining layer of glow and refill the
combustion chamber with wood - in accordance with picture 20. The
intensity of the combustion process should be set with the “air inflow
adjustment slider”. The correct flame should have a light-yellow color
and a length of approx. 20-40 cm, depending on the power of the boiler,
after approx. 2-3 minutes from charging. If there are problems to obtain
the correct flame in a short time - you should increase the opening of a
flow damper and set the target position after firing up.
Picture 20. Method of fuel arrangement
Never stand in front of the fireplace insert door while
opening. Burn risk.
The odor of paint from the body will be released during the first several
hours of combustion. This is completely normal. You should strongly
vent the room at that time. Check the tightness of joints once again
when fuel is completely burned out and equipment has been cooled
down.
Housing components will be very hot during operation.
You must exercise caution.
For the fireplaces of higher power (ME, LA) and doors of the large
area such as e.g. version with side window panels, there can be a mo-
mentary draw back of smoke into the room during the opening of the
doors. It is normal for such types of fireplaces. If the amount of such
smoke is considerable and lasts for a whole duration of doors opening
then it is absolutely required to check possible causes acc. to the guide-
lines given in chapter 8.
During operation, doors in DEFRO HOME RIVA fireplace inserts
in the G version, can be only opened by lifting. The hinged door open-
ing for these versions is intended only for service purposes and it
should not be opened during combustion.
Hinged doors should not be opened during combustion
in the case of the G version of the DEFRO HOME RIVA
fireplace insert. Lifting upwards is a normal method for
opening of the lifted doors.
You should control the level of filling of the container with ash. Over-
filling of container results in a lack of cooling of the grate and limits air
supply for combustion. To empty the container you should damp a fire-
place, close the inflow of air for combustion and wait until the surface
and parts of the fireplace insert cool down. Then open doors of the
insert, remove the grate and take out the container. Remove ash from
the container and re-install it in the body of the insert. It is recom-
mended to empty the ash container prior to each successive start-up
of the equipment.
6.4. DAMPING
Damping is executed by closing the inflow of primary air. In such a
case you should wait until the fuel completely burns out in a natural
way.
If it is necessary to quickly damp a flame you should charge the
furnace chamber with dry sand or ash. It is not allowed to damp a flame
by pouring it with water because it may damage components of the
equipment.

After a longer break in equipment’s operation, you
should check the flow capacity of the flue.
6.5. LOW-TEMPERATURE CORROSION
Fireplace inserts with a water system should be operated with dif-
ferences between supply and return temperatures within the range 10-
20°C and return water temperature not smaller than 50°C. While oper-
ating, if the central heating water temperature is below 60°C, water va-
pour contained in flue gas condenses on fireplace's walls. During the
initial period of operation, the above-mentioned condensate may leak
from the fireplace.
Longer operation at lower temperatures may lead to corrosion re-
sulting in a shorter water system's life. Hence, it is not recommended
to use the fireplace insert if the temperature of water supplying the cen-
tral heating system is below 60°C.
To ensure the proper, failure-free and effective operation of the
fireplace insert it is recommended to use it with the water system, on
80% of its rated power and with a temperature of water in boiler not
lower than 65 °C. It is also recommended to install a mixing valve.
To ensure the correct operation of the water system it
should be protected against the corrosion caused by
the return of water with temperature below the dew
point from central heating system. The temperature of
the return water should have min. 50 ºC.
If the temperature of water supplying the central heating
system is below 60°C, water system operation leads to
intensified precipitation of tarry substances from burnt
fuel resulting in deposits of tar sludge in the heat ex-
changer and flue, reducing the efficiency of the fire-
place insert and, in the first instance, leads to the risk
of soot ignition in the chimney.
7. CLEANING AND MAINTENANCE
All operations related to the cleaning of all components
should be carried out when the fireplace is completely
cold. It is required to use protective gloves.
It is forbidden to clean the equipment (all painted com-
ponents and gaskets) using chemicals, liquids and
moist cloths, towels, industrial wipers etc. Discolora-
tions, sources of corrosion may occur if the mentioned
rules are not observed and they are not covered by the
warranty.
It is a good practice to ensure good ventilation of the
room during the cleaning of the fireplace.
7.1. BASIC OPERATIONS AND CLEANING BY THE USER.
Any service and maintenance works are to be carried out with me-
ticulous care and only by adults familiarized with this manual. The fire-
place insert should not be cleaned in the presence of children.
Any service and maintenance works are to be carried
out with meticulous care and only by adults familiarized
with this manual. The dry fireplace insert should not be
cleaned in the presence of children.
Protective gloves, glasses and headgear are to be worn
to operate the equipment.
7.2. CLEANING BEFORE EACH STARTING
Prior to every successive start-up of the equipment, the ash con-
tainer should be cleaned and emptied, handling the ash with due care.
Remove grate, then ash container (picture below) using handles, and
remove the remaining dust. Dust can be removed using a vacuum
cleaner only if it is completely cold. Use a vacuum cleaner adapted to
removing the particles of specified size for this purpose.
Picture 21. Removal of grate and ash-pan.
Re-install the ash container below the grate after the cleaning,
making sure that its position is correct.
7.3. WINDOW PANEL CLEANING
The window panel may be cleaned only and exclusively when the
fireplace does not operate and is at room temperature.
Before each cleaning of the glass pane, it is required to protect the
painted components and surfaces, and gaskets against flooding, be-
cause it has an impact on quicker wear and tear of the components.
We recommend using only the DH sponge to clean the glass
panes. We do not recommend using any liquid for cleaning of glass
panes or chemicals. The absence of protection of the cords surround-
ing the glass panes causes loss of their properties, soaking with chem-
icals and reactions with high temperature that results in damage to the
glass pane.
The sponge is intended only to clean the glass panes, it should not
be used for gaskets or metal parts. It is not suitable for cleaning of
glass panes with pyrolysis. The sponge may be used several times,
depending on the degree of soiling of the glass pane. Use the gray side
for cleaning and brush it off each time after use.
Do not use products that may scratch the glass pane. The ash may
contain substances that will scratch the glass ceramics.
The window panel in the DEFRO HOME RIVA fireplace insert in
the G version should be cleaned when doors are in the lifted position.
Fireplaces with front doors are equipped with locks in the upper part of
the doors frame (picture 22).
Picture 22. Location of locks allowing opening of the guillotine doors in
lifted position for the DEFRO HOME RIVA in the G version.

Guillotine doors with side window panel (DEFRO HOME RIVA ver-
sions BP and BL G) may be opened by tilting. They have two locks
(picture no. Picture ), which unlocks the doors and allows opening them
like in the classic BP and BL version.
Do not use abrasive products and do not spray the
product for window panel cleaning on painted parts and
gaskets of fireproof doors (cord made of ceramic fiber).
Do not open doors to clean the window panel during
operation of the fireplace. Cleaning of window panel is
possible only when the equipment is cold.
Lifting of the doors in the G versions of the DEFRO
HOME RIVA fireplace inserts is a routine type of their
opening during operation. Hinged opening of the doors
is intended only for maintenance purposes and they
should not be opened in such a way when the flame is
burning inside the fireplace
Picture 23. Location of locks allowing opening of the guillotine doors in
hinged position for the DEFRO HOME RIVA in the BP and BL version
and view of the doors in a tilted position.
7.3.1. DOORS/GASKETS
Abrasive surfaces of doors and closing mechanisms should be oc-
casionally lubricated with graphite grease. Carry out inspection and
cleaning of the whole stove prior to each heating season. Pay special
attention to the condition of gaskets, and replace them if necessary.
7.3.2. FURNACE CHAMBER
Clean the furnace chamber of the insert periodically, depending on
moisture content and type of wood used.
7.3.3. FLUE
In compliance with applicable regulations, you should clean the
flue twice (2) a year. The flue should be cleaned by a chimnysweep
company and this fact should be documented in this manual.
Flue gases coming out of the blocked chimney are dan-
gerous. Chimney and connector should be kept clean.
They should be cleaned before each heating season.
After a longer break in equipment’s operation you
should check the flow capacity of the flue.
7.3.4. WATER SYSTEM
At least twice a year you should carry out inspection and mainte-
nance of all components ensuring safe operation of the water unit and
central heating system, including the safety valve and thermal safety
valve. If a longer break in operation of the fireplace insert is planned
and if it is possible that the temperature will fall below 0°C then you
should discharge water from the central heating system to prevent
freezing of water in the system and its damage. Check filling of the
central heating system with water prior to each start-up after a longer
break in operation of the fireplace insert.
•At least twice a year you should carry out inspec-
tion and maintenance of safety valve, thermal
safety valve and other components ensuring safe
operation of the water system and whole central
heating system.
•Check the level of water in the DEFRO HOME RIVA
fireplace insert after each longer break in opera-
tion.
7.4. PERIODIC INSPECTION BY AUTHORIZED SERVICE
After the heating season, it is necessary to clean the chamber
through which flue gas is flowing. This cleaning is obligatory and is in-
tended to remove all combustion residues.
Periodic inspection of the equipment should be carried
out only by a qualified manufacturer’s service.
7.5. DOORS DISASSEMBLY
1. Slide protecting ring downwards maximally.
2. Open the doors.
3. Lift the doors fully upwards to remove bottom pin of the hinge
from a sleeve.

19 | Page
4. Tilt doors from bottom to outside to ensure that bottom pin of
the hinge is outside the frame.
5. Lower the doors to ensure that upper pin of the hinge leaves
upper opening of the frame and remove the doors
7.6. WINDOW PANEL DISMANTLING
It is possible to disassemble the window panel after the doors have
been disassembled. The best way is to disassemble the window panel
when the doors are in a horizontal position (e.g. when such doors lie
on the table).
Picture 24. Window panel dismantling from doors.
7.7. DISASSEMBLY OF DEFLECTORS
1. Lift deflector (1) with fixing beam (2).
2. Lower the beam down holding the deflector.
3. Move the beam forward to the maximum extent.
4. Lift and align the deflector, to place it above the structure
holding the beam.

5. Slide the deflector to the right (or left).
6. Slide the deflector slightly to the front. One side of the deflec-
tor should be in free space between the shifted beam, rear
and side wall of the fireplace and the lower free end of the
deflector. Remove deflector in such position
Disassembly of steel deflector (item 23 in picture Picture ), located
on flue gas outlet is based on removal of fixing screw - as presented in
the below figure.
7.8. DISASSEMBLY OF HEAT-RESISTANT CERAMIC TILES
1. Remove grate.
2. Remove plates laying on floor of the insert.
3. Remove the screws fixing vertical plates.
4. Remove side plates first.
5. Remove corner plates at the end.
7.9. INSPECTION HOLES
The DEFRO HOME RIVA fireplace inserts with lifted doors (G ver-
sions) are equipped with inspection holes in the walls of the body.
These holes are intended to ensure access to the doors mechanisms
during the adjustment and maintenance operations performed by the
qualified service. Before removal of the covers of the inspection holes,
it is required to remove the heat-resistant claddings of the furnace
chamber.
