CONNECTION OF SMOKE DISCHARGE PIPE (2)
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 13cm minimum) and properly
insulate the pipe of the stove that passes through it, using adequate
insulation materials (thickness 1.35cm 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.
Always use pipes and unions with suitable gaskets
that guarantee a hermetic seal (class P1, reference
standard EN 1856-2).
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 accessories for
pellet stove)
It is absolutely prohibited to fit a grille on the end of
the discharge pipe, because it could lead to poor
running 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
IT IS ALSO ADVISABLE NOT TO EXCEED 6 METRES IN
LENGTH WITH THE PIPE Ø 80 mm
