Connection to the flue pipe
The flue pipe must have internal dimensions not larger
than 20x20 cm, or diameter 20 cm. In the event of
larger dimensions, or of the flue pipe being in poor
condition ( for example cracks, poor insulation, etc.),
it is advisable to fit a stainless steel pipe of suitable
diameter inside the flue pipe throughout its length,
right up to the top.
Check with suitable instruments that there is a draught
between 10 Pa and 12 Pa. This type of connection
ensures the evacuation of the fumes even in the event
of a temporary power cut.
At the bottom of the flue pipe, provide an inspection
cap to allow periodic checking and cleaning, which
must be done annually. Make a gas-tight connection
to the flue pipe, using pipes and connectors as
recommended by us.
You must ensure that a windproof cowl should be
fitted which complies with the standards in force
Connection to an external flue with insulated or
double-wall pipe
The only type of pipe which is permissible is insulated
(double-walled) stainless steel, smooth on the inside,
fixed to the wall.
Flexible stainless steel pipe must not be used. At the
bottom of the flue pipe, provide an inspection cap to
allow periodic checking and cleaning, which must be
done annually. Make a gas-tight connection to the flue
pipe, using pipes and connectors as recommended by
us. You must ensure that a windproof cowl should be
fitted which complies with the standards in force.
Check with suitable instruments that there is a draught
between 10 Pa and 12 Pa.
Connection to the flue pipe
For proper functioning, the connecting pipe between
the stove and the chimney or flue duct must have a
slope of not less than 3% in the horizontal stretches,
the length of which must not exceed 2 metres and
the vertical distance between one tee connector and
another (change of direction) must not be less than
1,5 m. Check with suitable instruments that there is
a draught between 10 Pa and 12 Pa. At the botton
of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done
annually.
Make a gas-tight connection to the flue pipe, using
pipes and connectors as recommended by us.
You must ensure that a windproof cowl should be
fitted which complies with the standards in force.
Connection to the ducting pipe (if present)
To each air outlet on the back can be connected only
one pipe with diameter 80 mm and length up to 2
meters with no curves.
