4Measured distance at 90° from the roof surface = 1,3 mt
• The chimney flue must be sealed from fumes.
• It must have a vertical run without narrowing. It must be realized with fume and condensation resistant materials with ther-
mal 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 flammable materials with an air gap or with insulating materials. Check the distan-
ce 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.
• Auxiliary exhaust fans cannot be installed neither along the chimney nor on the chimney pot.
• The inner section of the chimney flue 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:
•minimun Ø100 mm
•recommended max Ø180 mm
• Made the efficiency of the chimney flue overhauled by an expert stove-repairer and if necessary cover the chimney flue with
materials in compliance with current regulations.
• The flue system must be placed on the roof.
• The chimney flue must be provided CE in accordance with EN 1443 regulation. Please find attached an example of label:

3.4 HEIGHTDEPRESSION
The depression (draught) of a chimney flue depends also on its height. Check the depression with the values provided at FEATU-
RES a pag. 29. Minimum height 3,5 meters.
3.5 MAINTENANCE
• The fumes extraction pipes (fumes conduit + chimney flue + 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 flue 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.

3.6 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.
• The hole width for fumes exhaust must be the double of the chimney flue width and fitted in a way that the fume exhaust is
assured also in case of wind.
• It should prevent the infiltration of rain, snow and animals.
• The outlet height in the atmosphere must be away from the reflux area caused by the roof structure or by obstacles laying
nearby (see Fig. 2).

3.8 CHIMNEY FLUE CONNECTION
Your pellet stove works through a fume draught forced by a fan. 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 flue should be short in order to favor the draught and to avoid con-
densation in the pipes.
• The fume conduit should be equivalent or longer than the outlet joint ones (Ø 80 mm).
• 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.
SYSTEM TYPE Ø80 mm PIPE Ø100 mm PIPE

Maximum length (with 1 union) 6,5 mt 10 mt
Maximum length (with 3 unions) 4,5 mt 8 mt
Maximum number of unions 3 3
Level section (minimum inclination 3%) 2 mt 2 mt
Installation at a height above 1200 m a.s.l. NO Obligatory
• Use a plate pipe for stoves of Ø80 mm or Ø100 mm depending on the type of system and with silicone gaskets.
• It is forbidden to use metal, fibre cement or aluminium flexible pipes.
• For change of direction it is obligatory always to use a union (with angle > 90°) with inspection plug which enables an easy
periodic cleaning of the pipes.
• Please assure you that after the cleaning the inspection plugs are sealed with its efficient gasket.
• It is forbidden to exhaust flue gases directly from the wall towards the outside and closed spaces also at open top.
• The fume conduit must be placed at a distance of minimum 500 mm from flammable or heat-susceptible components.
• It is prohibited to connect more than one wood/pellet (*) or any other type of appliance (vent cowling...) to the same flue.
(*) unless there are national derogations (for instance in Germany), which under suitable conditions allow for the installation of
several appliances in the same fireplace. In any case, strictly follow the product/installation requirements of the relative regulations/
legislation in force in that country.

• External chimney flue entirely made up of insulated stainless steel pipes, i.e. with double wall of minimum Ø100/120 mm: all
must be firmly attached to the wall. For chimney against wind effects please (see Fig. 4).
• Ducting system through T-unions which enables an easy cleaning without disassembling the pipes.
We recommend to check with your chimney flue 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).

2External air inlet
• The room must be endowed with an external air recycling for a good climate in your ambient.
• The air inflow from outside to the inner occurs directly, through an opening on the external wall of the room (see Fig. 9).

WALL3PLUS - TILE3PLUS - MOON - LEAN3PLUS

• Bedrooms, garages, and store of flammable materials are excluded.
• The air inlet should have a total net surface of 80 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 floor with an external grid against birds. In such a way it cannot be ob-
structed by any object.
• In case of installation with sealed-chamber the air inlet is not necessary.
4.2 COMBUSTIBLE AIR INLET FOR SEALEDCHAMBER INSTALLATION
Check FEATURES a pag. 29 if the purchased stove has a sealed-chamber. If the stove is endowed with a sealed-chamber and
you want also the whole installation with sealed chamber, please read the following instructions:
• It is necessary to extract the air for combustion directly from outside.
• Use a tube with minimum Ø60 mm and maximum 2 meters lenght; to connect see the back of the stove.
• French standards require installation in double-walled flues (concentric system). The combustion air is drawn from the cavity.
• During installation step is necessary to verify the minimum distances required for the combustible air inlet as (for example) an
open door or window causes a vortex which could remove the combustible air necessary to the stove (see the underlying scheme).
• On the external wall it is necessary to install a curve at 90° to protect the combustible air inflow from wind effects: turn the
curve inlet downwards, see Fig. 10.
• Endow the curve with an external shield grid against birds in such a way that it cannot be obstructed by any object.
Check with your local authorities if exists any restrictive regulation regarding the combustible air inlet: if pre-
sent, they must be applied
In some countries and/or regions the installation with sealed-chamber is obligatory: in case of doubt, please
follow the most restrictive regulations.
