8 CHIMNEY FLUE
8.1 INTRODUCTION
This chapter about the Chimney Flue has been drawn up in cooperation with Assocosma (www.assocosma.org)
and is based on European Standards (EN 15287 - EN 13384 - EN 1856 - EN 1443 - UNI 10683:2012).
It provides instructions for a good and correct execution of the chimney ue but it does not absolutely replace
the current standards which the qualied manufacturer/installer should comply with.
Please check with your local authorities if exists any restrictive regulation which regards the
combustible air inlet, the fumes exhaust system, the chimney ue and the chimney pot.
The company declines any responsibility regarding the bad running of the stove if it is due to the use of a no
correctly dimensioned chimney ue which does not respect current regulations.
8.2 CHIMNEY FLUE
• The chimney ue or chimney is of great importance for the correct running of the heating appliance.
• It is fundamental that the chimney ue is perfectly built and always maintained with a perfect efciency.
• The chimney ue must be sole with insulated stainless-steel pipes or installed on the existing chimney ue.
• Both this solutions must be endowed with an inspection door.

2Roof inclination ≥10°
390°
4Measured distance at 90° from the roof surface = 1,3 mt
• The chimney ue must be sealed from fumes.
• It must have a vertical run without narrowing. It must be realized with fume and condensation resistant
materials with thermal insulation and able to last against usual mechanical stresses.
It must be insulated to avoid condensation and to reduce fume cooling effects.
• The stove must be spaced out from fuels or ammable materials with an air gap or with insulating materials.
Check the distance with the chimney manufacturer.
• The chimney entrance must be placed in the same room where the appliance is installed or otherwise in
the adjacent room and it must be provided with a solid and condensation collection chamber under the
entrance, accessible through the sealed metal gate.
• The inner section of the chimney ue can be round (the best one) or square and the jointed sides must have
a minimum radius of 20 mm.
• The section dimension must be minimum Ø160 mm and maximum Ø180 mm.
• Made the efciency of the chimney ue overhauled by an expert stove-repairer and if necessary cover the
chimney ue with materials in compliance with current regulations.
• The ue system must be placed on the roof.
• The chimney ue must be provided CE in accordance with EN 1443 regulation. Please nd attached an
example of label:
Fig. 3 - Example of label
It is important to adequately insulate the ue since the fumes leave the range at temperatures
above 100°C in order to avoid damaging condensation.
An inspection hatch should be tted to the base of the ue.

8DEMETRA
EN
8.4 HEIGHT-DEPRESSION
The depression (draught) of a chimney ue depends also on its height. Check the depression with the values
provided at FEATURES page 37. Minimum height 4,5 meters.
8.5 MAINTENANCE
• The chimney ue must be cleaned, since the soot and unburnt oil deposits reduce its section so blocking the
draught. In great quantities they can are up.
• The fumes extraction pipes (fumes conduit + chimney ue + chimney pot) must always be cleaned, scrubbed
and checked by an expert stove-repairer, in compliance with current regulations, with the instructions of the
stove-manufacturer and the directives of your insurance company.
• In case of doubts, please follow the most restrictive regulations.
• Have your chimney ue and chimney pot checked and cleaned by an expert chimney sweep at least once
a week. The chimney sweep has to release a written declaration about the security of the system.
• Not cleaning compromise safety.
8.6 CHIMNEY POT
Fig. 4 - Anti-wind chimney pots
The chimney pot is important for the correct running of the heating appliance:
• We recommend using an anti-wind chimney pot, see Fig. 4 page 8.
• The hole width for fumes exhaust must be the double of the chimney ue width and tted in a way that the
fume exhaust is assured also in case of wind.
• It should prevent the inltration of rain, snow and animals.
• The outlet height in the atmosphere must be away from the reux area caused by the roof structure or by
obstacles laying nearby (see FEATURES page 37).

• The room must be endowed with an external air recycling for a good climate in your ambient.
• The air inow from outside to the inner occurs directly, through an opening on the external wall of the room
(see Fig. 6 page 9); otherwise it occurs indirectly by air suction from rooms adjacent to the one to ventilate
(see Fig. 7 page 9).
• Bedrooms, garages, and store of ammable materials are excluded.
• The air inlet should have a total net surface of 100 sqcm2: the aforesaid surface is to widen if inside the room
there are other activated appliances (for example: electric ventilators for foul air suction, cooker hoods, other
stoves, etc...) which depress the environment.
• At switched on appliance it is necessary to check that the pressure fall between the room and the outside
does not exceed 4,0 Pa value: if necessary widen the air inlet (EN 13384).
• The air inlet must be realized at a height close to the oor with an external grid against birds. In such a way it
cannot be obstructed by any object.
• In case of installation with sealed-chamber the air inlet is not necessary.
8.9 CHIMNEY FLUE CONNECTION
Your stove works through a natural draught. It is obligatory to check that all pipes are realized in compliance
with the following regulation on material selection: EN 1856-1, EN 1856-2 e UNI/TS 11278. All must be effected by
specialized personnel or companies as provided by UNI 10683:2012.
• The connection between the appliance and the chimney ue should be short in order to favor the draught
and to avoid condensation in the pipes.
• The fume conduit should be equivalent or longer than the outlet joint ones.
• Some stove models are endowed with a lateral and/or back exhaust. Check that the unused exhaust is
sealed with the plug given with standard equipment.

• Ducting system through T-unions which enables an easy cleaning without disassembling the pipes.
We recommend to check with your chimney ue manufacturer the safety distances which
must be respected and the type of insulating material. The aforesaid regulations are valid
also for holes made on the wall (EN 13501 - EN 13063 - EN 1856 - EN 1806 - EN 15827).
9 FUEL
9.1 FUEL
• The allowed fuel is rewood and its derivatives (lignite blocks, compressed sawdust, etc.) with a maximum
water content of 20%.
• To obtain good rewood, it must be seasoned outside for at least 2 years in a place protected from the
weather.
• Using humid wood or waste bark could create condension and creosote into the ductions and in the hearth.
A heat yield of humid wood is great lower than dry wood.

Fig. 11 - Wood positioning
• To know the lenght of wood log to use, check the dimensions of stove combustion chamber.
• It is advisable to place the wood in horizontal position (see Fig. 11 page 13) and adjust the air ow with the
aid of the register.
• To ignite proper ignitier products can be used.
It is forbidden to use any type of liquid combustible!
It is forbidden to burn wood processing waste containing glue or paint, waste in general
and cardboard!
• Here following some information about the quality of different type of woods:
TYPE OF WOOD QUALITY % PERFORMANCE
Oak Excellent 100
Hornbeam Excellent 100
Ash Very good 92
Maple Very good 91
