2.5. CONNECTION OF SMOKE DISCHARGE PIPE
When making the hole for the passage of the smoke discharge pipe, it
is necessary to take into account the possible presence of flammable
materials. If the hole will be going through a wall made of wood or any
other material which is sensitive to heat, the INSTALLER MUST first
of all use the special wall union (diam. 13cm minimum) and properly
insulate the pipe of the stove that passes through it, using adequate
insulation materials (thickness 1.3 - 5cm with minimum thermal
conductivity of 0.07 W/m°K).
The same is true if the stove pipe must run through vertical or
horizontal stretches passing in proximity (min. 20cm) to the heat-
sensitive wall.
As an alternative we recommend the use of insulated pipe, which can
also be used on the outside to avoid condensation.
The combustion chamber works in low pressure. The smoke duct for
the discharge of fumes will also be under low pressure when connected
to an efficient flue pipe as directed.
Pipes and unions with suitable gaskets must always
be used, to guarantee a hermetic seal.
All sections of the smoke duct must be inspectable and
removable to enable periodic internal cleaning. Tee
connectors with inspection caps should be used.
Position the stove bearing in mind all the instructions and
considerations above.
IMPORTANT!
All 90 degree changes of direction in the flue pipe
must be fitted with suitable tee connectors to allow
the possibility of inspection (see the pellet stove
accessory list).
It is absolutely prohibited to fit a grille on the end of
the smoke discharge pipe, because it could lead to
poor operation of the stove.
FOR CONNECTION TO THE FLUE PIPE, NOT MORE
THAN 2-3 METRES OF HORIZONTAL PIPE MUST BE
USED AND NOT MORE THAN THREE 90° CURVES
MUST BE USED
NOT ADVISABLE TO EXCEED A LENGTH OF 6 LINEAR
METRES OF PIPE Ø 80 mm.
THE DIRECT DISCHARGE OF THE
COMBUSTION PRODUCTS MUST BE
PROVIDED ON THE ROOF, AND THE SMOKE
DUCT MUST SATISFY THE SPECIFICATIONS
PROVIDED FOR BY CURRENT LAWS AND
STANDARDS ON THE SUBJECT (UNI 10683)
