4.4 INSTALLATION OPERATIONS
Set up the gas and electricity supply lines based
on the installation design.
4.4.1 Air heater mounting preparations
Versions for ceiling installation (WR and
WD): Once the unit’s position has been
determined, bend the supplied paper template
on the dashed line and apply it to the ceiling
with adhesive tape (fig. 17).
a) Indicate the position of the four holes to be
made for installing the unit by means of screw
anchors or another system that is suitable
for the type of structure.
b) On the wall indicate the position of the two
holes that must go through the wall for the
exhaust and intake ducts. These holes must
be made as perpendicular as possible to the
wall with a core drill having a diameter of 70
mm (fig. 17).
The positions for the electric power supply
cable entrance and the gas delivery tube are
also shown on the template. They can be
brought to these positions depending on the
type of system chosen.
c) Cut a section of aluminum pipe with a
diameter of 70 mm that is equal to the
thickness of the wall. These segments must
then be installed in the wall as a sheath for
the ducts.
d) Use the following procedure to remove the
right angular panel of the air heater casing:
First remove the two fastening screws on the
front. Then use the tip of the screwdriver as
a lever to free the fastening springs on the
rear. Free the left panel’s fastening springs
in the same way, by pulling sideways until
they are released.
Version for wall installation (W): Once the
unit’s position has been determined, bend the
supplied paper template on the dashed line and
apply it to the wall with adhesive tape (fig.18)
a) Indicate the position of the holes to be made
(Four holes for installing the unit by means
of screw anchors, and two holes that go
through the wall for the exhaust and intake
ducts. These holes must be made as
perpendicular as possible to the wall with a
core drill having a diameter of 70 mm).
The positions for the electric power supply
cable entrance and the gas delivery tube are
