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, and mental
capabilities 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 equipment consid-
ering 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 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 the fireplace 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
furniture, curtains etc. The minimum distances are
given in point 5.2 of the operating manual.

6 | Page
•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 with non-flammable material.
•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 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 fireplace insert to air intake
from outside using a suitable pipe and through a spe-
cial outlet located at the back of the equipment.
•Doors in the devices equipped with a pair of doors lo-
cated on the opposite sides of the furnace should not
be opened at the same time!!!
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 sale or giving the equipment to the other user
you should always make sure whether the product has
the manual enclosed.
•Request a new copy from authorized sales outlet in the
DEFRO company if it has been lost.
3. INTENDED USE

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.
4. TECHNICAL SPECIFICATION
4.1. DESIGN
Body (1, pictures 1, 2, 3) of the DEFRO HOME INTRA fireplace
insert is a steel jacket, with a combustion chamber located inside (2).
Floor creating 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
chamber is restricted by steel doors (3) with 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 (11) (air intake) equipped with adjustment mechanism
(12). Air intake is located on the floor of the fireplace insert. Openings
for the flue gas afterburning system (14) are additionally located in the
rear wall of the furnace chamber.
Flue gases are removed to the chimney through a flue (16) located
in the upper wall of the fireplace insert.

Fireplace is delivered on a pallet, foil-wrapped and is fully assem-
bled. Scope of delivery can include additional components and subas-
semblies, according to the order. The components which are standard
equipment are specified in table
4.4. FUEL PARAMETERS
Fireplace insert is intended for combustion of wood from deciduous
trees (oak, hornbeam, ash, beech, birch) with 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
briquet.
It is not allowed to use wet wood (extensive contamination of fire-
place and soot emission and decrease of energy efficiency of the de-
vice).
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 operation of the equipment and can lead to loss
of warranty and decline of the liability for the product.
Fireplace is not a furnace intended for combustion of
wastes and forbidden fuels cannot be combusted in it.
Wood should be seasoned minimum two (2) years. Fir-
ing with wet wood, with low calorific value, decreases
the efficiency and has an adverse influence on dry
stove lifetime.
It is not recommended to use softwood and resinous
woods as a fuel. It causes intensive smoke concentra-
tion 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
Fireplace is delivered on a pallet, foil-wrapped and is fully assem-
bled. It is recommended to transport fireplace insert, in such packing
condition, as close as possible target location for installation, what will
minimize possibility of damage to 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.
Fireplace insert is to be stored in a non-heated room, under a roof
and with efficient ventilation.
Before the installation you should check completeness of the de-
livery, its condition and remove all transport protections!
In version with lifted doors (G versions) it is obligatory to check the
arrangement of ropes with carabiners to ensure that they are led verti-
cally on both sides of the unit, do not catch on the other components
and do not jam the mechamism.
Before first lifting of the doors in the G version fire-
places you should absolutely remove the transport pro-
tections!
Failure to observe the above recommendation may
cause problems in operation of the guillotine mecha-
nism 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 INTRA fireplace insert should be in-
stalled in compliance with the requirements of the cur-
rently applicable standards and legal regulations and
the detailed regulations of the target country. In Poland
these conditions are regulated by the Regulation of the
Minister of Infrastructure of 12 April 2002 on technical
conditions which should be fulfilled by buildings and its
location. (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 test methods.
The fireplace insert should be installed in a suitable location allow-
ing 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 fireplace insert installation. Check
minimum safe distances from materials susceptible to heat or inflam-
mable materials such as load-bearing walls and other walls or wooden
components, furniture etc. An exemplary installation of a fireplace in-
sert is presented in picture 34.
Installation of the fireplace insert should observe the following
safety rules:

17 | Page
•minimum distance 80 mm on the side and rear of the equip-
ment 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 front wall, where the me-
dium inflammable materials cannot be located.
•objects made of highly inflammable materials should be lo-
cated at distance minimum 2500 mm from the furnace, while
for ME, XL and XLA versions this distance should be equal
to min. 3000 mm
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.
Picture 34. 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!!!
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.
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 single-family building should
transfer 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 the 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 special
structure distributing the weight on a larger area.
The flooring in the room, where the fireplace is to be
installed, 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.
It is forbidden to install fireplace inserts in the G version
in so-called “hot” installations. Such installation will
void the warranty.
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 air
grilles. These openings should be made in a way ensuring that they
cannot be plugged. They should be ended with grilles. The exhaust
grille for the XLA version should be located at a distance not smaller
than 70 cm from the ceiling.
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
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.
Fireplaces in the G version are not intended for a so-called “hot”
installation due to the required cooling of the doors mechanism. Instal-
lation of the DEFRO HOME INTRA G fireplace insert in such a system
will void the warranty. It is indicated to use a bigger expansion joint, in
particular between front of the body and the installation (it should be
from 20 to 30 mm), what translates into longer and trouble-free opera-
tion of doors mechanism.
The effective area of the inlet grilles (bottom) should be selected
correspondingly to the power of the insert. It is assumed that it should
equal to 40 - 60 cm2per 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.
The effective area of the outlet grilles (top) should be bigger by
approx. 40% from the effective area of the inlet grilles.
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, in a distance of ~40cm from the ceiling of the room. It pre-

vents heating of the ceiling in the room, 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.
Outlets from the exhausts, which are operated with the heater in
the same room or in the rooms connected with ventilation, may be trou-
blesome.
If the additional heat source is installed then it is required to ensure
supply of a sufficient amount of air for combustion and ventilation.
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
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 sys-
tem for air distribution, when the hot air will raise upwards to the cham-
ber in heating ducts by way of thermal lifting forces.
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.
Picture 35. Hot air distribution system.
5.3.2. FORCED SYSTEM FOR HOT AIR DISTRIBUTION
The application of forced system for hot air distribution (DGP) re-
quires the installation of an 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 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 inflow of air in the minimum amount required for the 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 fireplace insert should have a through
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 36. Connection of fireplace insert to external air intake.
5.5. INSTALLATION TO THE 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.
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).
As an alternative it is recommended to use insulated industrial
pipe, which can be also used outdoors, to avoid the occurrence of con-
densate.

Picture 37. Connection of fireplace insert to flue depending on the
version (XSM and XLA version on the left, the other versions on the
right).
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 use of the “T”
component, should not exceed 4.
For the version without an elbow on the flue after the outlet from
the flue, it is required to use a straight section of pipe of a distance
equal to double the diameter of the insert’s flue.
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-sections with the maximum ratio
between two sides equal to 1.5.
It is forbidden to use mechanical exhaust ventilation
when the insert is not connected to external air intake.
The fireplace insert should not be used if the chimney
draught is too low.
6. USAGE AND OPERATION
6.1. 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, odor of paint, silicone and other ma-
terials used for the execution of the installation will disappear after sev-
eral fire ups. However, we remind you that they are not harmful to
health.
It is good practice to ensure efficient ventilation during
first firing-up because small amounts of smoke and
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.
6.2. FIRST START-UP AND OPERATION
Before first start-up it is obligatory to seal the equip-
ment in accordance with the enclosed manual.
Firing from 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 38).
Then, open 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.
closed/open
Picture 38. Setting of slider for air inflow adjustment.
If the draught in the chimney is not sufficient then you may unseal
by minimum opening of the fireplace doors during initial firing up stage.
If the fireplace insert is not supplied with the air from outside then it is
required to supply 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 a wood - in accordance with picture 39. In-
tensity of combustion process should be set with the “air inflow adjust-
ment slider”. Correct flame should have a light-yellow color and length
of approx. 20-40 cm, depending on 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 opening of a flow damper
and set the target position after firing up.
Picture 39. 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 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, XLA) and doors of 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 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 guidelines
given in chapter 8.
During operation, doors in DEFRO HOME INTRA fireplace inserts
in the G version can be only opened by lifting. The hinged door opening
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 INTRA
fireplace insert. Lifting upwards is a normal method for
the opening of guillotine doors.
It is forbidden to open both doors at the same time when
the fire inside the T version (tunnel) fireplace is burning
because it may start a fire.
You should control the level of filling of the container with ash.
Overfilling of containers results in a lack of cooling of the grate and
limits air supply for combustion. To empty this container you should
damp a fireplace, 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. Re-
move ash from the container 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.
6.3. 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.
7. CLEANING AND MAINTENANCE
All operations related to cleaning of all components
should be carried out when the fireplace is completely
cold and does not operate. It is required to use protec-
tive 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 dry
fireplace 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.
7.1.1. 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.
Re-install the ash container below the grate after the cleaning,
making sure that its position is correct.
Picture 40. Removal of grate and ash-pan for emptying purposes.
