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 suita-
ble 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 tem-
porary power cut. 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 (Fig. 1) .
Connection to an external flue with insulated
or double-wall pipe
The only type of pipe which is permissible is insula-
ted (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 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 (see table page 21-24) .
Connection to the flue pipe
For proper functioning, the connecting pipe betwe-
en 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 instru-
ments 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 cle-
aning, which must be done annually. Make a gas-
tight connection to the flue pipe, using pipes and
connectors as recommended by us.
