5.2.1 Connection to the flue gas venting system
Exhaust pipe or fitting
For the assembly of the exhaust pipes it is imperative to use non-flammable materials that are
resistant to combustion products and any condensates.
It is forbidden to use flexible metal pipes and asbestos cement for connecting the stove to the
flue, also for pre-existing exhaust channels.
There must be continuity between the exhaust pipe and the flue so that the flue does not lean on
the stove.
The exhaust pipes must not pass through rooms in which the installation of combustion devices is
forbidden.
The assembly of the exhaust pipes must be carried out in such a way as to ensure that they are
airtight for the operating conditions of the appliance, as well as to limit the formation of
condensates and prevent them from being conveyed towards the appliance.
The assembly of horizontal sections must be avoided where possible.
Where roof or wall exhaust outlets have to be reached that are not coaxial in relation to the
exhaust outlet from the appliance, the direction changes must be made using open elbows no
greater than 45° (see figures below).
For heat generating devices equipped with an electric exhaust fan, i.e. all products made by
Extraflame, it is necessary to observe the following instructions:
•
Horizontal sections must have a minimum slope of 3% upwards.
•
The length of the horizontal section must be as short as possible, and in any case no
greater than 3 metres.
•
No more than four direction changes may be used, including the one resulting from the use
of the “T”-element. (When four bends are used, use double wall piping with a 100 mm
diameter.)
In any case, exhaust pipes must be sealed in relation to combustion products and condensates, as
well as insulated, if they pass outside the installation room.
It is forbidden to use elements in counter-slope.
The exhaust channel must allow soot recovery and cleaning using a swab.
The exhaust channel must have a constant cross-section. Any changes in cross-section are allowed
only at the flue connection. It is forbidden to run other air feed channels or piping for utilities
inside the exhaust channels, even if they are oversized. No manual draught regulation devices can
be mounted on forced draught appliances.
