2.7. CONNECTION TO THE FLUE PIPE
The flue pipe must have internal dimensions not greater than 20x20
cm or a diameter of 20 cm; in the case of larger dimensions or poor
operation of the flue pipe (e.g. cracks, poor insulation, etc.) it is
advisable to insert a stainless steel pipe of a suitable diameter all the
way up to the top. Fig.5
Check with suitable instruments that there is a minimum draught of 10
Pa.
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.
It is compulsory to check that an anti-wind chimney has been installed,
in accordance with current standards.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.
2.8. CONNECTION TO AN EXTERNAL FLUE WITH
INSULATED OR DOUBLE-SKINNED PIPE
The outside flue must have minimum internal dimensions of 10X10 or a
diameter of 10 cm and maximums 20x20 cm or a diameter of 20 cm;
Check with suitable instruments that there is a minimum draught of 10
Pa. Fig.6
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.
It is compulsory to check that an anti-wind chimney has been installed,
in accordance with current standards.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.
2.9. CONNECTION TO FLUE PIPE OR SMOKE DUCT
For proper functioning, the connecting pipe between the stove and the
chimney or flue duct must have a slope of not less than 3%. The length
of the horizontal stretch must not exceed 2/3 metres, and the vertical
distance between one tee connector and another (change of direction)
must not be less than 1.5m.
Check with suitable instruments that there is a minimum draught of 10
Pa. Fig.7
At the bottom of the flue pipe, provide an inspection cap to allow
