bendable type in stainless steel. Connect the
ducts to the doubling device using metal clamps
and tighten them to ensure a good seal on the
fitting. With the doubling device connected in
this manner, place it in the housing and block it
into position using cement mortar.
Make sure to respect the position indicated
in fig. 17, so that only the circular fitting
projects from the finished wall, while the
interior of the doubling device is flush with
that wall.
WARNING! The seal of the connector between
the doubling device and the appliance is
created by a special gasket (fig. 18). Make
sure that the wall on which the air heater is
installed is perfectly flat, so that the
subsequent attachment of the appliance does
not change the coupling.
Assemble the ducts in the chases up to the
relative external terminal, carefully checking any
joints (if a rigid tube is used make sure that the
special unions and gaskets are mounted
correctly).
WARNING! It is recommended to insulate the
duct by using insulating material that is
suitable for the temperatures generated (for
example, glass fibre mattress for temperatures
up to 200°C), to prevent condensation from
forming inside the duct and/or to avoid cracks
in the plaster due to the high temperature. At
the end of the previous operations close the
chases, making sure that the cement mortar
completely covers the ducts and that there
are no empty spaces.
Place the previously used template on the wall,
centering the position of the intake/exhaust fitting
onto the corresponding centre of the walled
doubling device, and mark the position of the
three holes to attach the appliance. The holes
should be drilled using an Ø 8 mm bit for
expansion bolts.
To adapt the intake/exhaust fitting of the
appliance to the coupling with the doubling device
connector, do the following operations:
a) remove the three screws inserted in the fitting
on the appliance (they will not be used again)
b) mount the aluminium flange Ø 92 mm,
inserting the ring gasket and attaching it on
the appliance fitting using the three screws
supplied with the kit. Check that the ring
gasket fits correctly into its housing (fig. 18).
4.4.4 Appliance wall mounting
a) Appliance with standard supply -
Installation Type C
Lift the appliance and, putting the intake/exhaust
duct at the beginning of the hole, push it toward
the wall until contact is made.
Adjust the position of the appliance and attach
it with the expansion screws that were
previously inserted into the wall. On the
exterior, check that the intake/exhaust duct
ends flush with the wall.
Insert the external wind protection terminal on
the duct and mark the position of the hole for
the expansion bolt to be drilled in the wall (fig.
15). After drilling the hole, re-insert the terminal
and attach it permanently, checking its stability.
b)Appliance with accessories for separate
intake and exhaust ducts - Installation
Type C
52
Lift the air heater and slowly bring it closer to
the wall until coupling the two intake/exhaust
connectors located on the doubling device
and on the appliance.
Making sure not to change the coupling
described above, adjust the position of the
appliance and attach it using the expansion
screws that were previously inserted into
the wall.
In both cases described above, it is
recommended to use two persons to lift and
position the air heater to avoid any possible
damage to the wall or the appliance.
4.4.5 Gas connection
Mount the gas on-off valve supplied with the
appliance using the special gasket. Connect the
gas supply line to the valve which is equipped
with a female threaded attachment G 3/8".
WARNING!: The valve must be located in a
position that can be easily accessed by the
user.
Check the seal on the gas piping and make sure
that it was created in conformity with the current
standards regarding gas installations.
4.4.6 Electrical connections
Ensure that a single-phase, 230 V ~ 50 Hz
electric power supply is available.
The appliance must be properly insolated by
means of an omnipolar circuit-breaker with
