4.2.2. Forced convection (COMFORT AIR VF)
Also in this case, it is necessary to connect the stove unit to an external
air intake (B) with a pipe Ø 100 (optional) using the flange located on
the back of the stove unit. (figure 1) If it is not possible to connect
directly to the air intake, at least connect the flange to the outside of
the cladding.
This operation is necessary to ensure proper operation of the
COMFORT AIR KIT. If the combustion air intake is not connected
directly to the an external air intake (B), it will be obligatory to provide
an air intake (A) that has a free passage of not less than 150 cm 2 so
that natural fresh air flows into the room of installation (preferably
inside the cladding).Figure 3
For the ducting of hot air, it is necessary to install a reduction flange Ø
100 on the upper connections of the stove unit. Then insert in the
flanges of the hoses Ø 100 the COMFORT AIR outlets (C).
Then proceed as set forth in
paragraph 5.3 “Installation of comfort air
kit".
