
The national and local provisions should be met.
Equipment should be installed in compliance with the
legal standards applicable in the given location, region
or country.
The equipment should not be used by a person (in-
cluding children) of impaired physical, sensory, mental
capabilities and by persons without experience and re-
quired knowledge provided that such operation is no
t
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 b
y
adults. Errors and incorrect setting 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
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 sub-
strate will resist the force of the fireplace insert consid-
ering its weight.
In case of disturbances in operation the equipment can
be restarted only when the occurred problem has been
removed and the equipment is brought back to original
condition.
The user is fully responsible for misuse of the produc
t
and relieves DEFRO from any civil and criminal liabil-
ity.

A
ll types of modifications or replacement of equipmen
t
parts with non-original components or without authori-
zation may present a risk for the operator and relieve
DEFRO from any civil and criminal liability.
Incorrect installation or maintenance (incompatible
with contents of this manual), can cause injuries o
f
people, animals or property damage. Then DEFRO
shall be relieved of any civil or criminal liability.

Part of fireplace insert surface is very hot (doors, han-
dle, 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 a fireplace insert when the glass
is cracked.
Do not place and dry the underwear on the equipment.
Possible dryers for hanging underwear or simila
r
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 min. 400 mm
between hot parts of the fireplace insert and medium
inflammable materials; otherwise use commerciall
y
available insulation materials. Apply this hint also fo
r
furniture, curtains etc. Minimum distances are given in
point 5.2 of the operating manual.

6
It is absolutely forbidden to use flammable liquid fo
r
equipment firing up.
If the substrate, on which the equipment is located, is
made of inflammable materials, such as parquet o
r
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 case of failure or in-
correct 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.
Do not allow contact with water, and first of all, do no
t
wash any varnished coatings before they cure. The
coating of new devices is not an anti-corrosion coating,
heat-resistant paint only gains its protective properties
after curing under the influence of heat (after several
firings).
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 rooms with fire pro-
tection 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 canno
t
be exposed to adverse effects of the weather.
It is not recommended to place body of the fireplace
insert directly on the floor and if such floor is made o
f
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 what can
also disturb air intake.
Always make sure and check whether doors of the
combustion chamber are tightly closed when the
equipment is operating.
Equipment consumes exact amount of air which is re-
quired for combustion process; it is recommended t
o
connect the iron stove to air intake from outside using
suitable pipe and through a special outlet located a
t
the back of the equipment.
ADDITIONA INFORMATION
In case of any problems you should contact sales out-
let or qualified personnel authorized by DEFRO. Re-
quest original spare parts if the repair is necessary.
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
case of sale of giving the equipment to the other use
r
you should always make sure whether the product has
the manual enclosed.
Request a new copy from authorized sales outlet in

4.3. FUEL PARAMETRS
A fireplace insert is intended for combustion of wood from decidu-
ous trees (oak, hornbeam, ash, beech) with a moisture content below
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
briquette.
It is not allowed to use wet wood (extensive contamination of fire-
place and soot emission and a 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 for the users (toxic flue gas from
chemicals).
Use of bad quality fuel or incompatible with the abov
e
-
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
product.
The fireplace is not a furnace intended for combustio
n
of wastes and forbidden fuels cannot be combusted i
n
it.
Wood should be seasoned minimum two years. Firin
g
with wet wood, with low calorific value, decreases th
e
efficiency and has an adverse influence on dry stov
e
lifetime.
It is not recommended to use softwood and resinou
s
woods as a fuel. It causes intensive smoke concentra-
tion and the necessity to clean the equipment and flu
e
more often.
It is forbidden to combust coal, wood from tropica
l
trees, chemical products, liquid fuels etc., e.g. oil, alco
-
hol, petrol, naphthalene, laminated, impregnate
d
boards etc., paper, cardboards, old clothes, wastes.
DEFRO Sp. z o.o. Sp. k. does not accept liability fo

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 fireplace insert, in such pack-
ing condition, as close as a possible target location for installation, what
will minimize the possibility of damage of device housing.
All remaining parts of the packing should be removed in such a
way that it will not pose any hazard for 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.
Fireplace insert
DEFRO HOME RIVA should be installe
d
in compliance with the requirements of the currently ap
-
p
licable standards and legal regulations and detaile
d
regulations of the target country. In Poland these con
-
ditions are regulated by the Regulation of the Ministe
r
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 a
s
amended) and Polish Standard PN-EN 13229:2002 Inse
t
appliances including open fires fired by solid fuels. Re-
quirements and tests.
A fireplace insert is to be stored in a non-heated room, under a roof
and with efficient ventilation.
Prior to installation it is to be determined if all parts have been de-
livered and if they are in good technical condition.
In case the inserts with raised doors (G version). it is absolutely
necessary to check the arrangement of the links with the carabiners so
that they run vertically on both sides of the roller, do not catch on other
elements and do not block the mechanism.

11
5.2. WORKING ENVIRONMENT
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 power supply 230V/50Hz,
equipped with a suitable flue gas exhaust system,
equipped with an external ventilation system,
equipped with an earthing system with CE certificate.
Correct setting of the insert is necessary to obtain the satisfactory
heating level of the residential unit. Prior to assembly it is necessary to
select a suitable position for stove installation. Check minimum safe
distances from materials susceptible to heat or inflammable materials
such as load-bearing walls and other walls or wooden components, fur-
niture etc. Exemplary installation of fireplace insert is presented on
picture 13.
Installation of the fireplace insert should observe the following
safety rules:
minimum distance 80 mm from side and rear of the non-flam-
mable materials,
minimum distance 400 mm from side and rear of the medium
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 in distance minimum 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 case of contact with wooden wall or wall made of other inflammable
material it is appropriate to insulate flue gas discharge pipe.
Picture 13.Exemplary installation of fireplace insert.
WARNING !!!
Lack of expansion joint may be a reason of equipment damage
what is connected with loss of the warranty rights.
In
the cas
e
of the floor made of inflammable materials i
t
is appropriate to prepare a plane protecting the floo
r
and execute protection in accordance with the stand
-
ards applicable in the given country.
Fireplace insert should be located on a substrate with suitable
load-bearing capacity. In accordance with the Polish Standards each
square meter of the floor slab in the single-family building should trans-
fer a load of 150 kg. If this condition is fulfilled the fireplace insert man-
ufactured 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 with building designer to reinforce the floor slab or execute special
structure distributing the weight on a larger area.
Flooring in the room, where the stove is to be installed,
should be properly dimensioned, to maintain the load.
To ensure correct operation of fireplace insert you should ensure
suitable inflow of air required for combustion (it is appropriate to ensure
approx. 40 m3/h) in accordance with the installation standards and
standards applicable in the given country. The volume of the surround-
ing environment should not be less than 30 m3. You should assume
that 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 correct discharge of hot air
from the hood you should install exhaust openings ended with ventila-
tion grilles. This opening should be made in a way ensuring that they
cannot be plugged. They should be ended with grilles.
The active area of the grille should be selected correspondingly to
the power of the insert. It is assumed that is should equal to 40 - 60
cm2per 1 kW of the 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 recommendations of the applicable standards.
Temperature over the insert, inside the hood, is very high. There-
fore it is necessary to install a decompression relief plate inside the
hood, in distance ~40cm from the ceiling of the room. It prevents heat-
ing of the ceiling in the room, heat losses and forces installation of ex-
haust grilles below it emitting the heat from the relief chamber over the
insert. Relief grilles are installed alternately on both sides of the hous-
ing - below and over relief plate.
Before installing the fireplace insert with raised door
s
(versions G), check the correct operation of the liftin
g
mechanism, in particular the arrangement of the line
s
with carabiners.

5.3. HOT AIR DISTRIBUTION SYSTEM
5.3.1. GRAVITY SYSTEM FOR HOT AIR DISTRIBUTION
DEFRO HOME RIVA fireplace insert gives back approx. half of the
power to the environment when the air is being heated. In case of heat-
ing of small areas, e.g. room where the fireplace insert is installed, and
adjacent rooms, you should select gravity system for air distribution,
when the hot air will raise upwards to the chamber in heating ducts by
way of thermal lifting forces.
Picture 14.Hot air distribution system.
Using of 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
Application of 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
case you should use a pipe connecting flue with an 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 fo
r
the given area and will correctly design connection sys-
tem and arrangement of the individual parts.
5.4. CONNECTION TO EXTERNAL AIR INTAKE
Room, where the fireplace insert is installed, should be equipped
with an inflow of air in the minimum amount required for correct com-
bustion process and for room ventilation. This can be done by execut-
ing fixed vents in the wall directed to the outside or through independ-
ent or common ventilation ducts.
The external wall near the stove should have through the opening,
protected with 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 external air intake.
5.5. INSTALLATION TO FLUE
Fireplace insert should be connected to the individual flue. Size of
chimney draught should equal:
minimum draught −6 ± 1 Pa,
medium, recommended draught −12 ± 2 Pa.
maximum draught −15 ± 2 Pa.
Prior to permanent installation of the fireplace insert you should
make sure whether a condition of recommended draught is met. If the
draught it too small then you should disassemble a steel deflector of
flue gas outlet (part 23 on figure 1) and re-check whether the condition
of recommended draught is met.
Picture 16. Connection of fireplace insert to flue.
During execution of opening for flue gas discharge pipe you should
consider the possible occurrence of inflammable materials. If the open-
ing will pass through the wooden wall or wall made of material sensitive
to heat then you should obligatory maintain minimum distance 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).
As an alternative is it is recommended to use an insulated indus-
trial pipe, which can be also used outdoors, to avoid the occurrence of
condensate.
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 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 use of the
“T” component, should not exceed 4.
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 a 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.
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 steel deflector on flue gas outlet.
5.6. INSTALLATION IN CENTRAL HEATING SYSTEM
DEFRO HOME RIVA fireplace insert is equipped with water sys-
tem 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 open
and closed system.
The connection of 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 its location.
Standard PN-EN 12828:2006 - Heating systems in buildings
- Designing of water central heating systems;
The central heating system is to meet requirement
s
specified by the Polish Standard PN-91/B-02413 on th
e
protection of open system water heating devices an
d
pressure vessels.
In case of installation of the fireplace insert in a countr
y
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 the water system to the central heating system and then
enter working pressure in the system to check its tightness. Fireplace
insert should be embedded when all leaks in the water systems have
been excluded.
Pictures 17 and 18 presents connection diagrams for the water
system of the DEFRO HOME RIVA fireplace insert in the heating sys-
tem.
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 the 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 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 syste
m
ensuring continuous water inflow, also if the elec-
tric power is not available.
Protecting heat exchanger is intended only fo
r
emergency heat collection and should not be use
d
as a flow, utility water heater.
To ensure correct operation of the water system it is necessary to
meet the condition that temperature of water returning from the CO
system is not lower than 50 °C (dew point for wood with moisture con-
tent 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 applying various methods, e.g. by setting higher temperature
of water in the water system and adjustment of temperatures in heated
rooms using thermostatic valves or using mixing systems. Function of

thermal protection against drop of return water temperature below the
dew point is implemented by a mixing three-way thermostatic valve (4),
which based on the measured value of installed temperature sensor
opens correspondingly valve with hot water mixing it with cold water
from return - in case of examples (Picture 17 and Picture 18).
It is required to install thermal protection in the syste
m
preventing the return of water with a temperature belo
w
the dew point (50 °C). Lack of such protection leads t
o
a dramatic decrease in heating efficiency and damag
e
to the equipment. Failure to observe this recommenda
-
tion may cause loss of the warranty.
It is required to installed safety valve (12) in the closed system. Its
task it to protect the 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%.
Valve should be installed as a close heat source as possible: it can
be installed directly in free supply socket or on pipe supplying the in-
stallation, in an easily accessible location.
If the allowable pressure is exceeded the safety valve discharges
an 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 sewage system).
It is recommended to use safety fittings, the so
-
calle
d
safety unit, which consists of a safety valve, manomete
r
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 inser
t
by welding results in loss of warranty!!!
Fireplace insert installation should be carried ou
t
by person or company with suitable qualification
s
and authorizations.
It is in user’s interest to look after that installatio
n
is made in accordance with the regulations i
n
force and that installing company gives a warrant
y
for correctness and good quality of workmanshi
p
what should be confirmed by a stamp and sign o
n
warranty card of the stove.
The hydraulic system of the water system of fire

lace insert should be made in compliance wit
h
the currently applicable standards and regula
-
tions. All national and local provisions should b
e
met!
6. USAGE AND OPERATION
6.1. FILLING WATER SYSTEM WITH WATER
Make sure that the CO system is correctly filled with water, which
should be clean, clear and without any admixtures prior to starting up.
Filling 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 whole central heating system Water should have the fol-
lowing parameters:
pH reaction:
•8.0 ÷ 9.5 - in steel and cast iron systems;
•8.0 ÷ 9.0 – made of copper and mixed materials
steel/copper;
•8.0 ÷ 8.5 - for systems with aluminium radiators;
total hardness < 20 °f,
free oxygen content <0.1 mg/l, recommended <0.05mg/l,
chlorides content <60mg/l.
Before connecting the fireplac
e
with the water syste
m
to the old central heating system user should carry ou
t
flushing to remove sludge remaining in the radiator
s
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 18). 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 signalling 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 refil
l
water during fireplace insert's operation, espe
-
cially when its temperature is high as it may lea
d
to its damage or crack.
Water can be refilled only due to its loses by evap
-
oration.
Other decrements such as system leakage are in
-
admissible as they may lead to the creation o
f
boiler scale resulting in permanent damage to th
e
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
warming and cooling down stage what may cause slight squeaks. This
is an absolutely normal phenomenon because a structure of the fire-
place is made rolled steel and this phenomenon shall not be considered
as a defect.
Do not stay near the stove during several first fire ups. It is also
required to vent the room. Smoke, the odour of paint, silicone and other
materials used for execution of the installation will disappear after sev-
eral fire ups. However, we remind that they are not harmful to health.
It is good practice to ensure efficient ventilation durin
g
first firing-up because a small amount of smoke an
d
odour or paint and other materials will be emitted fro
m
the fireplace insert.
No to use non
-
installed fireplace insert. Test firing up i
s
an exception.
6.3. FIRST START-UP AND OPERATION
Prior firing up you should set a slider of air inflow adjustment to the
maximum opening (marking on the handle, presented on the adjacent
picture). Then, open the doors of the insert and place fire starter and
fragmented wood, then charge approx. 1 kg of dry hardwood, fire up
and close the doors.
It is forbidden to use other materials than described i
n
this manual for firing up, in particular flammable chem
-
icals such as: oil, petrol, solvents and others.
After firing up refill combustion chamber with wood, placing fuel in
a way that reasonably fills the combustion chamber. Recommended
single fuel charge is given in table 2. Method of fuel laying is shown on
the adjacent picture.

15
Picture 19.Method of fuel arrangement during firing up
Picture 20.Setting of slider for air inflow adjustment
The intensity of the fuel combustion process should be adjusted by
proper setting of the air supply adjustment slider. Doors of fireplace
insert should be closed during operation of the fireplace insert.
The odour 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 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.
You should control the level of filling of the container with ash.
Overfilling of container results in lack of cooling of the grate and limits
air supply for combustion. To empty the container you should damp a
fireplace, close inflow of air for combustion and wait until 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 con-
tainer and re-install in the body of the insert. It is recommended to
empty ash container prior to each successive start-up of the equipment.
Do not fill the furnace completely with wood. The charge should
not exceed 1/3 of the volume of the combustion chamber. You should
use only hardwood (recommended beech, oak, hornbeam) of low mois-
ture content (below 20%).
During combustion the doors should be opened only when the fuel
is being added. Prior to adding the wood you should wait until flames
fall down and charge is completely burnt out leaving an igniting layer of
glow. After firing up refill combustion chamber with wood, placing fuel
in a way that reasonably fills the combustion chamber for the combus-
tion period expected by the user based on personal experience. The
intensity of the fuel combustion process should be adjusted by proper
setting of the air supply adjustment slider.
Never stand in front of the fireplace insert door whil
e
opening. Burn risk.
6.4. DAMPING
Damping is executed by the closing inflow of primary air. In such
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 fur-
nace 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.
A
fter a longer break in equipment’s operation yo
u
should check flow capacity of the flue.
6.5. LOW TEMPERATURE CORROSION
Fireplace inserts with water system should be operated with differ-
ences between supply and return temperatures within the range 10-
20°C and return water temperature not smaller than 50°C. While oper-
ation, if the central heating water temperature is below 60°C, water va-
pour contained in flue gas condenses on the fireplace's walls. During
the initial period of operation, the above mentioned condensate may
leak from the fireplace.
Longer operation at a lower temperature may lead to corrosion re-
sulting in shorter water system's life. Hence, it is not recommended to
use the fireplace insert if the temperature of water supplying central
heating system is below 60°C.
To ensure proper, failure-free and effective operation of the fire-
place 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 correct operation of the water system i
t
should be protected against the corrosion caused b
y
the return of water with a temperature below the de
w
point from the central heating system. The temperatur
e
of return water should have min. 50 ºC.
If the temperature of water supplying central heatin
g
system is below 60°C, water system operation leads t
o
intensified precipitation of tarry substances from burn
t
fuel resulting in deposits of tar sludge in the heat ex-
changer and flue, reduces efficiency of the fireplace in
-
sert and, in the first instance, leads to the risk of soo
t
ignition in the chimney.
7. CLEANING AND MAINTENANCE
A
ll operations related to cleaning of all component
s
should be carried out when the fireplace is completel
y
cold. It is required to use protective gloves.
It is a good practice to ensure good ventilation of th
e
room during 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.

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 using handles, and remove the re-
maining dust. Dust can be removed using vacuum cleaner only if it is
completely cold. Use vacuum cleaner adapted to remove the particles
of a specified size for this purpose.
Picture 21.Removing grade and ash container.
Re-install the ash container below the grate after the cleaning,
making sure that its position is correct.
7.3. WINDOW PANEL CLEANING
It is recommended use a dry brush to clean the ceramic glass. If
the contamination is significant use suitable cleaning agent spray and
spray little amount and then clean the window panel with a cloth.
In the G version of the DEFRO HOME RIVA fireplace insert, the
glass should be cleaned when the door is in a tilted position. Fireplaces
with front doors have bolts in the upper part of the door frame (figure
21).

7.3.1. DOORS/GASKETS
Abrasive surfaces of doors and closing mechanism 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, replace them if necessary.
7.3.2. FURNACE CHAMBER
Clean 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
two times a year. The flue should be cleaned by a chimneysweep com-
pany and this fact should be documented in this manual.
Flue gases coming out of blocked chimney are danger
-
ous. Chimney and connector should be kept clean.
They should be cleaned before each heating season.
A
fter a longer break in equipment’s operation yo
u
should check 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 safety valve and thermal safety valve.
If a longer break in operation of fireplace insert is planned and if it is
possible that 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 to fill of the central heating system
with water prior to each start up after a longer break in operation of the
fireplace insert.

Inspection holes are intended only for use by the quali
-
fied service of the manufacturer during adjustment an
d
maintenance works.
7.10. SHUTTING THE STOVE DOWN
It is recommended completely shutdown the fireplace and clean
the equipment when each heating season is finished.
8. TROUBLESHOOTING
Some anomalies indicating irregularities in operation can occur
during operation of the equipment. It can be caused by incorrect instal-
lation of the equipment without observation of the applicable building
regulations or provisions of this manual or by external causes e.g. nat-
ural environment.
Below you will find the most frequent causes of incorrect of the
equipment with their solutions.
Smoke draw back when the doors are opened:
the too rapid opening of the doors (open the doors slowly);
if chimney damper has been installed as a chimney draught
regulator - open the chimney damper each time when the
doors are opened;
insufficient air inflow to the room, where the equipment is in-
stalled (ensure proper ventilation in the room or supply air to
the combustion chamber in compliance with guidelines in the
manual);
atmospheric conditions: low pressure, mists and precipita-
tion, sharp changes in temperature;
insufficient chimney draught (carry out chimneysweep in-
spection of the flue).
Insufficient heating or damping:
too low amount of fuel in the furnace (charge furnace in com-
pliance with the manual);
the too high moisture content of wood used for combustion
(use wood with moisture content <20%) a large part of ob-
tained energy lost in water evaporation process:
too low chimney draught (carry out chimneysweep inspection
of the flue).
Insufficient heating despite good combustion in combustion
chamber:
low calorific “soft” wood (use wood as recommended in the
manual);
the too high moisture content of wood used for combustion
(use wood with moisture content <20%);
too fragmented wood, too thick chunks of wood:
Excessive contamination of window panel:
low intensity of combustion (combustion with very small
flame, use only dry wood as a fuel);
using resinous softwood as a fuel (use dry hardwood as a
fuel foreseen in the insert operating manual).

20
The too high temperature in the water system or too high differ-
ence of temperatures between water system and water in the cen-
tral heating system:
circulating pump in the central heating system does not op-
erate (pump switched off, damaged or power failure);
air lock of the central heating system;
closed cut-off valves.
Correct operation can be disturbed by an atmospheri
c
condition (air moisture content, fog, wind, atmospheri
c
p
ressure) and sometimes by closely located high facili
-
ties.
In case of repeated problems you should turn to chim
-
neysweep company to confirm the reason of such con
-
dition and to indicate the best solution for the problem.
9. MEASURES IN CASE OF FIRE IN THE FLUE /SOOT IGNI-
TION/.
Systematic cleaning of smoke ducts should be per
-
formed to prevent soot ignition in the chimney.
Soot ignition in the chimney is burning of particles deposited inside
chimney (flue) channels; the deposits are formed in the course of heat-
ing equipment's operation and were not cleaned by chimney sweeps.
In the case of soot fire in the chimney the following recommendations
should be observed:
call Fire Brigade at 998 or 112, give information about what
is happening and give detailed directions what is happening
and hot to get to the given building;
damp a fire in the chimney by the closing inflow of cold air to
the furnace chamber;
close fireplace's door and cleaning holes tightly to cut off air
supply (due to lack of air the fire will eventually stop);
check the whole chimney channel for any cracks which might
result in fire spread to the rooms;
prepare fire quenching means, e.g. a fire extinguisher, a fire
blanket, a hose connected to the water system, water in a
container;
make rooms and necessary information available to the Fire
Brigade.
It is strictly forbidd
e
n to pour water into the chimney
-
the risk of a blowout.
Leaking chimney channels can be a source of burnin
g
sparks or very hot flue gas, including insensible carbo
n
monoxide.
Chimneysweep should be called after soot fire in th
e
chimney to perform cleaning of ducts and to inspec
t
their technical condition.
10. REMOVAL DUE TO WEAR-OUT
A fireplace insert is made of materials neutral for the environment.
After worn out of the insert’s parts connected with screws should be
disassembled by unscrewing and welded parts must by the cut. Ele-
ments of a stove are subject to standard waste disposal, mostly as steel
scrap. Take safety precautions during disassembly of the insert by us-
ing appropriate hand-held and mechanical devices as well as personal
protective equipment (gloves, clothes, apron, glasses, etc.).
