4.2.2 Duct length limits
If the duct passes directly through the external
wall, and if that wall has a thickness of more than
40 cm, an intake/exhaust duct with a length of 1
metre can be supplied on request. If the appliance
is installed with separated ducts, using the special
accessory, the length of the ducts must not be
greater than 6 metres, considered as the sum of
the layout of both ducts (for example: 3 m intake
+ 3 m exhaust, etc.), to ensure correct operation.
It should be remembered that a bend is
equivalent to a straight segment of about 50 cm.
If the exhaust duct layout is exposed to low
temperatures, prevent condensation from
forming by using suitable insulation on that duct.
4.3 OUTSIDE POSITIONING OF THE FLUE
GAS EXHAUST TERMINAL
The position of the flue gas exhaust terminal and
its distance from windows, ventilation openings,
etc. must comply with what is prescribed by the
current standards.
If the air heater is installed in rooms on the ground
floor and the exhaust faces sidewalks at the level
of pedestrians, a special protection grille must be
applied, which is supplied on request
(fig. 14).
4.4 INSTALLATION OPERATIONS
Set up the gas and electricity supply lines based
on the installation design.
4.4.1 Air heater wall-mounting preparations
(appliance with standard supply -
Installation Type C
12
)
Once the position and the height of the appliance
from the ground has been determined, use the
wall template from the cardboard packing to
indicate the positions of the holes to be made
(three holes to attach the appliance with an Ø 8
mm bit for expansion bolts, one hole for the
intake/exhaust duct with special hole cutter Ø 70
mm, to be made as perpendicular as possible to
the direction of the wall).
The template also indicates the positions of the
electric power supply cable and gas feeder pipe
entries.
4.4.2 Mounting the intake/exhaust duct
(appliance with standard supply -
Installation Type C
12
)
The intake/exhaust duct, supplied for walls up to
40 cm, consists of an aluminium pipe with
connector flange and an external terminal. Mount
the duct in the sequence described below:

Using the doubling device (supplied on
request), it is possible to create different
configurations of the air intake and flue gas
exhaust ducts, within specified limits. The
external terminals are not required to be
adjacent to each other.
