INSTALLATION

The assembly position must be chosen based 

on the environment, the discharge and the chim-

ney flue. Check, with your local authority, if there are 

more restrictive provisions regarding the oxidising air 

intake, the smoke discharge system including the 

chimney flue and chimney pot. 

The manufacturer cannot be held in any way liable 

in the event of installation non-compliant with legisla-

tion in force, 

of incorrect premises air exchange or electrical con-

nection non-conforming with standards and/or inap-

propriate use of the appliance. 

Installation must be carried out by a qualified techni

-

cian, who will issue the purchaser with a Declaration 

of Conformity for the system and will assume com-

plete responsibility for final installation  and resulting 

good operation of the product.

In particular, he should ascertain:

• there is an adequate oxidising air intake and good  

   smoke discharge compliant with the type of prod-

uct    installed;

• other stoves or devices installed do not cause 

   negative pressure in the room where the product is 

installed    (only for hermetic appliances, a maximum 

of 15 Pa depression in the surroundings is permitted);

•  when  the  product  is  on,  there  is  no  smoke  back 

draught in the surroundings;

• smoke evacuation is implement in total 

   safety (dimensioning, smoke seal, distances from 

   flammable materials..).

Once the position is decided where to install 

the product, you need to pay attention:

• if the floor is made of combustible material, 

   you should use protection in suitable material (steel, 

glass...) which also protects the front part from any 

falling burning fuel during 

   cleaning operations:

• that the floor guarantees adequate 

   load capacity.

   if the existing building does not meet this 

   requirement, you should take appropriate measures    

   (for example a load distribution plate).

3.1 AIR INTAKE

The installation premises of non-hermetic appliances 

must be sufficiently ventilated with specific openings, 

with particular attention on the 

position (they must NEVER be blocked), which consent 

air reintegration in the environment.

The air must be taken directly from outside (not from 

other rooms, garage, etc.) and must have a net useful 

section equal or higher than 80 

cm

2

 pellet burning stoves and thermostoves (EN 14785) 

and 100 cm

2

 for boilers (EN 303-5). 

The air intake is not necessary for 

installation of the hermetic appliances that take air 

directly from outside. Check and 

comply with the ventilation requirements for simul-

taneous operations with other combustion devices 

and in the presence of forced ventilation systems or 

hoods (refer to section 6.4 of UNI 10683).

3.2 SMOKE CHANNEL AND FITTINGS

The term smoke channel indicates the piping con-

necting the appliance to combustion with the 

chimney flue.

For heat generating appliances with an electric fan 

to expel the smoke, the following installation instruc-

tions must be followed, provided by the manufactur-

er concerning the maximum length and number of 

curves the smoke channels can have.

If no indications are given for maximum values or 

deriving from preliminary calculations according 

to UNI EN 13384-1, the following provisions must be 

applied:

• comply with the product standard EN1856-2;

• the horizontal sections must have a minimum slope 

   of 3% upwards;

• the length of the horizontal section must be  

   minimal and its projection on plan must not ex-

ceed 4 metres;

• 

the number of changes of direction including 

   introduction in the chimney flue and excluding  

   that by effect of using a “T” element 

   in the appliances with rear smoke output, must 

   not exceed 3;

• 

the changes of direction must not have an angle 

   over 90°(45° curve recommended);

• 

the section must have a constant diameter 

   equal to the output of the fireplace up to the      

fitting in the chimney flue;

• it is forbidden to use flexible metal and fibre ce

-

ment  piping,  furthermore  the  piping  must  guarantee        

pressurised sealing;

• 

the smoke channels must not cross premises 

   in which installation is forbidden of combustion 

   appliances;

• 

Use watertight piping with silicone gaskets.

In any case, the smoke channels must be 

sealed by combustion and condensate 

products, as well as insulated if passing 

inside the installation premises.

Assembly is not permitted of draught manual adjust-

ment devices on forced draught appliances.

You need to install a first vertical smoke channel sec

-

tion of at least 1 metre to guarantee correct smoke 

ejection.

All local and national legislation and European 

standards must be met when installing and using the 

the product.
