7.4 Room fan air suction connection
During the dry installation run, the air
intake position should be marked both
on the external wall and the cladding.
For model AC78 only
Standard solution (40÷60 m
2
rooms)
• The room fan must take in the air from outside
the cladding, through an appropriate duct, as
shown in Fig. 36. Where:
1)
Room air intake to the heating circuit fan, lo-
cated on the side of the cladding with protec-

7.5.1 Hood liner fitting for heating in a single
room
• Take the flexible pipe at the ends and stretch it,
accompanying it with a twisting motion.
Fig. 37
• Cut it to the desired length (no more than 200
cm) and mount the vents in the desired points.
• Fasten the tube (

The vents are fixed on the hood or on
a wall at a height of at least 1.8 ÷ 2.0 m
from the floor in order to prevent that
the outgoing hot air invests people.
The ducts should not be longer than 7÷8 m.
7.5.2 Channelled pipelines fitting for heating
in multiple rooms
To heat several rooms, it is possible to create
metal pipelines for air distribution according to
the following diagram:
• flexible aluminium hose - maximum length 7÷8
m per duct;
• smooth metal pipe or canalisation - length up
to 12 m on a single pipe; of 8÷9 m on double
duct.
Install a vent in the same room as the fireplace
and the second in another room of the house.
It is possible to connect the hot air delivery with a
flexible pipe up to the mouth of the distribution
channels.
The air distribution ducts must have an internal
section of 20x20 cm and be made of smooth gal-
vanised sheet metal and insulated with 30 mm
thick insulating material to avoid noise and heat
