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 insula-tion, 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 tempo-rary power cut. At the bottom of the
flue pipe, pro-vide 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. (Only in the room where the stove is
located, single-walled pellet stove pipes may be used).
Flexible stainless steel pipes may only be used when
connecting to a brick chimney. These should never be
used outside a brick chimney. At the bottom of the flue
pipe, provide an inspection cap to allow periodic che-
cking 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 chimney or flue duct
For proper functioning, the connecting pipe between the
stove and the chimney or flue duct must have a
slope
of
not
less
stretches. The total length should be as short as
possible (which must not exceed 0,5 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 bottom of the
flue pipe, provide an inspection cap to allow periodic
checking and cle-aning, which must be done annually.
