WOOD BURNING COOKER
INSTRUCTIONS MANUAL
Rev.01 (01/02/2022)

During combustion, thermal energy is released that signifcantly increases the heat of surfaces, doors, handles, controls, glass, exhaust
pipes, and even the front of the appliance. Avoid contact with those elements if not wearing protective clothing (protective gloves
included). Make sure children are aware of the danger and keep them away from the stove during operation.

FIRE SAFETY
When installing the product, the following safety measures must be observed:
a) In order to ensure sufition thermal insulation, respect the minimum safety distance from objects or furnishing components
flammable and sensitive to heat (furniture, wood sheathings, fabrics. etc.) and from materials with flammable structure (see Picture 5-
a). All the minimum safety distances are shown on the product data plate and lower values must not be used.
b) In front of the furnace door, in the radiation area there must be no flammable or heat-sensitive objects or material at a distance of
less than 100 cm. This distance can be reduced to 40 cm where a rear-ventilated, heat-resistant protection device is installed in front of
the whole component to protect.
c) If the product is installed on a non totally refractory floor, one must foresee a fireproof background. The floors made of inflammable
material, such as moquette, parquet or cork etc., must be covered by a layer of no-inflammable material, for instance ceramic, stone,
glass or steel etc. (size according to regional law). The base must extend at least 50 cm at the front and at least 30 cm at the sides, in
addition to the opening of the loading door (see Picture 5 -B).
d) No flammable components (e.g. wall units) must be present above the product.
The Product must always operate exclusively with the ash drawer inserted. The solid combustion residues (ash) must be collected in a
sealed, fire resistant container. The Product must never be on in the presence of gaseous emissions or vapours (for example glue for
linoleum, petrol etc.). Never deposit flammable materials near the Product.
! - During combustion, thermal energy is released which leads to considerable heating of the surfaces, doors, handles, controls, glass
parts, the flue gas pipe and possibly the front part of the appliance. Avoid contact with these elements unless using suitable protective
clothing or accessories (heat resistant gloves, control devices).
Ensure children are aware of these dangers and keep them away from the furnace when it is on.
When using the wrong fuel or one which is too damp, due to deposits present in the flue, a flue fire is possible.
IN A EMERGENCY
If there is a free in the flue connection :
a) Close the loading door and the ash drawer door
b) Close the comburent air registers
c) Use carbon dioxide ( CO2 powder ) extinguishers to put out the free
d) Request the immediate intervention of the Fire Brigade
! DO NOT PUT OUT THE FIRE WITH WATER.
When the flue stops burning, have it checked by a specialist to identify any cracks or permeable points.

(*) The proposed value are indicative. The installation must, in any case, be sized and verifed according to the general calculation
method in EN13384-1 or by another method of proven efciency.
(**) For those buildings in which the thermal insulation does not correspond to the instructions on heat protection, the heating volume of
the stoves is: favourable type of building (30 kcal/h x m3); less favourable type of building (40 kcal/h x m3); unfavourable type of
building (50 kcal/h x m3).
With thermal insulation in accordance with the regulations regarding energy saving, the heated volume is greater. With temporary
heating, in the event of interruptions which last more than 8 hours, the heating capacity is reduced by about 25%.
The declared technical data have been achieved by burning beech wood class “A1” according to the requirement EN ISO 17225-5 and
wood moisture content less than 20%. By burning a different kind of wood the efciency of the product itself could change and some
specifc adjustments on the appliance could be needed.

The heating of the environment is made by irradiation: through the external hot surfaces of the stove, the heat is radiated into the
environment.
The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.
PRIMARY AIR CONTROL (PRE-ADJUSTED)
SECONDARY AIR CONTROL (PRE-ADJUSTED)
The control regulation necessary in order to obtain nominal calorifc output is the following (see Cap. TECHNICAL DATA):
A –SMOKES control (Picture 7)
(Conversion of the cooker function to the cooker, bake oven and heating function).
The smokes control can be found on the top right plate of the cooker, between the top table and cooking door. This control has two
settings:
OVEN COOKING: when the bar is pushed to the back of the cooker, the combustion gases flow around the oven and directly into the
flue and up to the chimney.
HOB COOKING: when the control bar is pulled out, the combustion gases flow around the oven, heating it.
To ignite the flame follow the instructions below :
• Bring the flue gas control to the control bar pulled out.
• After having started the fire with small pieces of wood and waited until it is well lit.
• Bring the flue gas control to the control bar pulled in.
The control regulation during the ignition phase is the following :
FLUE
Essential requirements for correct appliance operation:
• the internal section must preferably be circular;
• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat,
combustion products and any condensation;
• there must be no narrowing and vertical passages with deviations must not be greater than 45°;
• if already used, it must be clean;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm. For the
rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough
and porous internal surfaces. Picture 1 shows some example solutions.
! For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
The draught created by your flue must be sufcient but not excessive.
A section of the flue which is too large can present a volume which is too large to heat and therefore cause operating difculties for the
appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a reduction in
draught.
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements provided.
The flue must be at a suitably distance from flammable or combustible material using suitable insulation or an air space.
It is FORBIDDEN to pass system piping or air ducts inside the flue. It is also forbidden to create moveable or fxed openings on the flue
itself, for the connection of further different appliances.

CHIMNEY POT
The flue draught depends on the suitability of the chimney pot.
It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the flue (Picture 2) .
As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3).
The chimney pot must meet the following requirements:
• Have an internal section equivalent to that of the chimney.
• Have a useful exit section of double the internal section of the flue.
• Be built so as to prevent rain, snow or any foreign body entering the flue.
• Be easy to inspect, for any maintenance and cleaning operations.
CONNECTION TO THE CHIMNEY
Products with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (except during the fuel
loading or ash removal phases).
Products with non-automatic door closing (type 2) must be connected to their own flue.
Operation with doors open is only allowed when supervised.
The connection pipe to the flue must be as short as possible, straight horizontal and positioned slightly in ascent, and watertight.
Connection must be carried out with stable and robust pipes,comply with all current Standards and Regulations and to those envisioned
by the law, and be hermetically secured to the flue. The internal diameter of the connection pipe must correspond to the external
diameter of the appliance flue gas exhaust stub pipe (DIN 1298).
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements provided.
The flue must be properly spaced from any flammable materials or fuels through a proper insulation or an air cavity. Minimum distance
safety 25 cm.
The chimney pressure (DRAUGHT) must be at least 12 Pa Pascal (=1.2 mm of water column). The measurement must always be carried
out when the appliance is hot (nominal calorific power). When the pressure exceeds 17 Pascal, it is necessary to reduce it through the
installation of an additional draught regulator (false air valve) on the exhaust pipe or in the chimney, according to the regulations in
force.
! For correct appliance operation, it is essential that sufficient air for combustion is introduced into the place of installation (see
paragraph VENTILATION AND AERATION OF THE INSTALLATION PREMISES).
VENTILATION AND AERATION OF THE INSTALLATION PREMISES
As the product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a sufcient quantity of
air is introduced. If windows and doors are airtight (e.g. built according to energy saving criteria), it is possible that the fresh air intake is
no longer guaranteed and this jeopardises the draught of the appliance and your health and safety.
There MANDATORY be sufcient quantity of air for combustion and re-oxygenation of the room to ensure the device will work properly.
There should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even when the
doors and windows are closed.
The air inlets must meet the following requirements:
• they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
• they must be made so as to make the maintenance operations possible;
• positioned so that they cannot be obstructed;
• Any extractor hoods in the room where the device is installed must not operate at the same time as this could cause smoke to enter
the room, even with the fireplace’s door closed.
The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and
ventilation), as long as the flow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a fire hazard, bathroom,
bedroom or common room of the building.
Ventilation is deemed sufficient when the room is equipped with air inlets according to the table:
Installation in premises with fire hazards is forbidden. Installation in residential premises in which, in any case, the depression measured
during installation between the internal and external environment is greater than 4 Pa .
All national, regional, provincial and municipal laws and standards in force in the country where the appliance is installed must be
complied with.

ALLOWED / NOT ALLOWED FUELS
Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood
should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.
Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device, since these
have a very high calorific value.
The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to burn
less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content involves the
disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack causing a
remarkable deposit of soot with following possible risk of fire of the same.
Fresh wood contains about 60% of H2O, therefore it is not suitable to be burnt.
It is necessary to place this wood in a dry and ventilated place (for example under a roof) for at least two years before using it.
Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood or wood treated with paints,
plastic materials; in this case, the warranty on the device becomes void.
Paper and cardboard must be used only to light the fire.
The combustion of waste is FORBIDDEN and would even damage the appliance and the flue, causing health damages and claims by the
neighborhood owing to the bad smell.
The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the night is not
possible.
* RESINOUS WOOD NOT SUITABLE FOR THE BURNING
ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the cast iron parts
(cleavage) of the product.
The declared technical data have been achieved by burning beech wood class “A1” according to the requirement EN ISO 17225-5 and
wood moisture content less than 20%. By burning a different kind of wood the efciency of the product itself could change and some
specifc adjustments on the appliance could be needed.

LIGHTING
WARNING: After the first ignition you can smell bad odours (owing to the drying of the glue used in the garnitures or of the paint) which
disappear after a brief using of the appliance. It must be ensured, in any case, a good ventilation of the environment. Upon the frst
ignition we suggest loading a reduced quantity of fuel and slightly increasing the calorifc value of the equipment. It is FORBIDDEN to use
any liquid substance as for ex. alcohol, gasoline, oil and similar.Never switch on the device when there are combustible gases in the
room.
To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to know the following
information:
• the construction materials of the involved products are not homogeneous, in fact there are simultaneously parts in cast iron, steel,
refractory material and majolica;
• the temperature to which the body of the product is subject is not homogeneous: from area to area, variable temperatures within the
range of 300°C -500°C are detected;
• during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as well as to cycles of intense use
or of absolute standstill when season changes;
• the new appliance, before being considered seasoned has to be subject to many start cycles to allow all materials and paints to
complete the various elastic stresses;
• in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal stress, as well as of wet paint.
This paint, although during the manufacture it is backed at 250 °C for some hours, must exceed many times and for a given period of
time the temperature of 350 °C before becoming completely embedded in the metallic surfaces.
Therefore, it is extremely relevant to take these easy steps during the lighting:
1. Make sure that a strong air change is assured in the room where the appliance is installed.
2. During the first starts, do not load excessively the combustion chamber (about half the quantity indicated in the instructions manual)
and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in the instructions
manual.
3. Repeat this operation for at least 4-5 or more times, according to your possibilities.
4. Then load more and more fuel (following in any case the provisions contained in the installation booklet concerning maximum load)
and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.
5. During the first starts, no object should be leaned on the appliance and in detail on enameled surfaces. Enameled surfaces must
not be touched during heating.
6. Once the «break-in» has been completed, it is possible to use the product as the motor of a car, avoiding abrupt heating with
excessive loads.
To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means. The openings for air
(primary and secondary) must be opened together. When the wood starts burning, you may load other fuels and adjust the air for
combustion according to the instructions on paragraph TECHNICAL DESCRIPTION.
Please always be present during this phase.
! Never overload the appliance (see cap. TECHNICAL DESCRIPTION / hourly consumption). Too much fuel and too much air for
combustion can cause overheating and therefore damage the appliance. The warranty does not cover the damages due to
overheating of the equipment.
LOW EMISSION FIRE LIGHTING
Smokeless combustion is a way of lighting a fire able to significantly reduce the emission of harmful substances. The wood burns
gradually from the top downwards, so combustion is slower and more controlled. Burned gases pass through the high temperatures of
the flame and therefore burn almost completely.
Place the logs in the hearth a certain distance apart as shown in the Picture 6. Arrange the largest at the bottom and the smallest at the
top, or vertically in the case of tall narrow combustion chambers. Place the fire starter module on top of the pile, arranging the first logs
in the module at right angles to the pile of wood.
Fire STARTER MODULE. This fire starter module replaces a paper or cardboard starter.
Prepare four logs, 20 cm long with a cross section of 3 cm by 3 cm Picture 6. Cross the four logs and place them on top of the pile of
wood at right angles, with the fire lighter (wax impregnated wood fibre for example) in the middle. The fire can be lit with a match. If
you want, you can use thinner pieces of wood. In this case, you will need a larger quantity.
Keep the flue gas exhaust valve and combustion air regulator open.
After lighting the fire, leave the combustion air regulator open in the position shown in according to the instructions on paragraph
TECHNICAL DESCRIPTION
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fne particle emissions.

NORMAL OPERATION
After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations (according to the instructions on paragraph TECHNICAL DESCRIPTION). You should always use the product with the
door closed in order to avoid damages due to overheating (forge effect). The inobservance of this rule makes the warranty expire.
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for
removing the ashes, while during the operation and the rest, the door of the hearth must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under
supervision.
IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The hearth door must always
remain closed during operation or rest.
With the controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. They have to be
opened according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most
part of the air for combustion flows through the secondary air register.
Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and too much air for the combustion
may cause overheating and then damage the stove. You should always use the appliance with the door closed in order to avoid
damages due to overheating (forge effect). The inobservance of this rule makes the warranty expire.
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 12 Pa 1,2mm of column of
water) is the following one: see chapter TECHNICAL DESCRIPTION. The appliance works as an intermittent operating appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of the
device is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor draught
requires a more precise adjustment of air for combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that
the combustion is not complete (it is necessary a greater quantity of secondary air).
WARNING: When fuel is added onto the embers in the absence of a flame, a considerable amount of fumes may develop. Should this
happen, an explosive mixture of gas and air may form, and in extreme cases an explosion may occur. For safety reasons it is
advisable to perform a new lighting procedure with the use of small strips.
USE OF THE OVEN (IF PRESENT)
Place the smoke controller in the position USE OF THE OVEN (see chap. TECHNICAL DESCRIPTION)
Thanks to the air flow for the combustion, the temperature of the oven may become remarkably affected. A sufcient flue of the
chimney andof the channels, well cleaned for the flow of burning smokes around the oven are fundamental for a good cooking result.
Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reach the medium level. The upper level
may be used to heat or grill.
The oven pan and the chrome plated oven grille may be located on different plans (see chapter Technical Description - ACCESSORIES).
When cooking food with high humidity, cakes with fruit or fruit itself, water of condensation will be produced. During the cooking
process some water vapour in the form of drops of condensed water can deposit onto the top and the side of the door. It is a physical
phenomenon.
By opening the door briefly and carefully (1 or 2 times, or even often in case of longer cooking times) you can let out the steam from the
cooking compartment and reduce condensation signifcantly.
OPERATION IN TRANSITION PERIODS
During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that
the combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the
air for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the
stabilization of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tight. In case of
doubt, DO NOT operate the product.
MAINTENANCE AND CARE
Check the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimney sweeper.
Let your chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the
aeration.
IMPORTANT: THE MAINTENANCE MUST BE CARRIED OUT ONLY AND EXCLUSIVELY WITH COLD DEVICE. You should only use
spare parts approved and supplied by Hoşseven. Please contact your specialized retailer if you require spare parts. YOU MUST
NOT MAKE ANY CHANGES TO THE DEVICE!!!

GLASS CLEANING
Thanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efcacy. Nevertheless
this can never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion of the
same. For the cleaning, it is possible to use specific products or a wet newspaper paper ball passed in the ash to rub it. Do not use
cloths, abrasive or chemically aggressive products by cleaning the hearth glass.
The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance
and for the cleaning of the glass.
! BREAK OF GLASSES : given that the glass-ceramic glasses resist up to a heat shock of 750°C, they are not subject to thermal shocks.
Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, their replacement is not
included in the warranty.
CLEANING OUT THE ASHES
All the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes Picture 7.
It is suggested to empty periodically the ash drawer and to avoid it filled completely in order not to overheat the grating. Moreover, it is
suggested to leave always 3-4 cm of ash in the hearth.
CAUTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped with an air-
tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the switching off and
complete cooling.
CLEANING THE FLUE
The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
The device should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield). An
excessive deposit of soot can cause problems in the discharge of smokes and fire in the flue.
The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper who
can simultaneously perform an audit of the flue (checking of possible deposits).
During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deflectors from the device in order to ease
the fall of the soot. The deflectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing
has been carried out, place them back in their seats.
CAUTION: The lack of the deflectors causes a strong depression, with a too fast combustion, an excessive consumption of
wood with related overheating of the device.
SUMMER STOP
After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth
and the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work
others possible appliances connected to the same flue.
We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the rope
seals, which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In
this case the seals must be replaced.
In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the hearth.
! If you want to keep for long the aesthetic look of the cooker it is important to protect its internal walls in row cast iron with neutral
Vaseline.
MAJOLICAS (IF PRESENT)
Hoşseven has chosen majolica tiles, which are the result of high-quality artisan work. As they are completely carried out by hand, the
majolica may present crackles, speckles, and shadings. These characteristics certify their precious origin.
Enamel and majolica, due to their different coefcient of dilatation, produce microcrackles, which show their authentic feature.
if you use a detergent or liquid, the latter might soak For the cleaning of the majolica we suggest you to use a soft and dry cloth;in and
highlight the crackles permanently.

PRODUCTS MADE OF NATURAL STONE (IF PRESENT)
Natural stone has to be cleaned with very thin abrasive paper or with an abrasive sponge. DO NOT USEany cleanser or fluid.
VARNISHED PRODUCTS (IF PRESENT)
After some years of product use a change in the varnished details colour is totally normal. This is due to the considerable temperature
range the product is subject to whenever in use and to the varnish ageing of time passing by.
ATTENTION: before any possible application of the new varnish, do clean and remove all the traces from the surface which has to be
varnished.
ENAMELLED PRODUCTS (IF PRESENT)
For the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive detergents.
IMPORTANT : After the cleaning do not let soapy water or any cleanser dry but remove them immediately. DO NOT use sandpaper or
steel wool
CHROMIUM-COMPONENTS (IF PRESENT)
If the components become bluish due to overheating, this can be solved with a suitable product for cleaning. DO NOT use abrasives or
solvents.
CAST IRON COOKING PLATE AND RINGS
IMPORTANT: to avoid rust DO NOT forget pots or pans on the cold cooking plate. This would create rust rings, unpleasant to see
and difcult to remove.
The cast iron cooking plate and the cast iron rings needs to be periodically cleaned by using sandpaper (grain 150) without
touching the enamelled parts.
To carry out the cleaning operation remove the smoke outlet spigot and the smoke pipe. The smoke compartment can be cleaned from
the front side of the oven (see chap. CLEANING SMOKE COMPARTMENT COOKERS) or from the top. In this case remove the cast iron
rings and the cooking plate, as well the smoke outlet spigot and the smoke pipe. The cleaning can be carried out by using a brush and a
hoover.
ATTENTION: once the cleaning operations are terminated all the parts have to be re-assembled hermetically.
MAINTENANCE OF THE OVEN (WHERE EXISTING)
To avoid the possible forming of rust it is recommended:
-To let the steam getting out of the oven to reduce the formation of any condensation by opening the door briefly and carefully (1 or 2
times, or more often in case of cooking food very humid and with longer cooking times);
- Remove the food from the oven once cooked. Letting the food to chill in the oven at a temperature below 150 °C results in the forming
of condensation;
- After cooking, leave the oven door partially open to dry out any condensation;
CALCULATION OF THE THERMAL POWER
There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorifc value necessary for a properly insulated room is 30 kcal/h per m3 (for
an external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m3.
Let’s suppose one wishes to heat a room of 150 m3 (10 x 6 x 2.5 m) in an insulated apartment. In this case, it is necessary to have 150
m3 x 35
W/m3 = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufcient.

1. Steel flue with double chamber insulated with material resistant to 400°C. Effciency 100% excellent.
2. Refractory flue with double insulated chamber and external coating in lightweight concrete. Effciency 100%
excellent.
3. Traditional clay flue square section with cavities. Effciency 80% good.
4. Avoid flues with rectangular internal section whose ratio differs from the drawing. Effciency 40% poor
1. Industrial chimney cap with pre-fabricated elements –it allows an excellent discharge of the smokes.
2. Handicraft chimney cap. The right output section must be at least twice as big as the internal section of the flue
(ideal value: 2.5 times).
3. Chimney cap for steel flue with internal cone deflector of smokes.
4. In case of flues side by side, a chimney cap must be higher than the other one of at least 50 cm in order to avoid
pressure transfers between the flues themselves.
The chimney cap must not show hindrances
within 10 m from walls, pitches and trees.
Otherwise raise it of at least 1 m over the
hindrance. The chimney cap must exceed
the ridge of the roof of at least 1 m.
