2.5. FLUE PIPE CONNECTION
The flue pipe connection is extremely important, and it should be
performed carefully and attentively. Stoves have a top or rear smoke
outlet.
The smoke outlet pipe must be fitted in such a way as to guarantee its
seal during the appliance's vacuum operation and avoid the formation
and conveying towards the stove of any condensation.
Any manual draught control devices inserted in the pipe should not
hermetically seal the internal section of the duct. These shutters should
be equipped with a suitable mechanism to avoid the complete rotation
of the valve in the closed position. The minimum safety opening surface
must be 3% of the through cross-section, and not less than 10 cm². If
the smoke duct has a horizontal section, the same should rise with a
minimum slope gradient of 3-5% (3-5 cm for every metre).
The tilted horizontal part should not be longer than 2 linear
metres.
The use of flexible pipes and fibre cement pipes is
forbidden. The smoke pipe must not cross rooms in
which it is forbidden to install combustion
appliances. The use of counter-sloping pipes is
forbidden.
2.6. CONNECTING THE STOVE TO THE FLUE PIPE
The smoke outlet pipe is designed by MCZ for the outlet of smoke
towards the top of the stove.
It is possible to bring the smoke outlet to the rear of the stove, by
turning the outlet pipe by 180° and unscrewing the two screws and
knocking out the pre-perforated panel at the rear of the stove.
In both cases, it is compulsory to take the cord supplied and join it,
then insert it between the smoke union and the pipe, in order to avoid
any smoke leakages, for instance in the case of a dirty or clogged flue
pipe.
