ASSEMBLY AND INSTALLATION INSTRUCTIONS
CONNECTION TO THE EXHAUST VENTING SYSTEM
EXHAUST CHANNEL OR PIPE
For the assembly of the exhaust channels it is imperative to use non-fl ammable materials that are resistant to
combustion products and any condensates.
It is forbidden to use fl exible metal pipes and asbestos cement for connecting the stove to the fl ue, also for pre-
existing exhaust channels.
There must be continuity between the exhaust channel and the fl ue so that the fl ue does not lean on the stove.
The exhaust channels must not pass through rooms in which the installation of combustion devices is
forbidden.
The assembly of the exhaust channels 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 fi gures
below).

Inspection
For heat generating devices equipped with an electric exhaust fan, i.e. all products made by Extrafl ame, 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
™
meters.
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 150 mm diameter.)
In any case, exhaust channels 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
