CLEANING THE FAN
Remove all the impurities found on the nets of the fan
guards. If the fan blades require cleaning, unscrew the
guards. Clean all the elements with compressed air.
ADJUSTMENT OF THE BELT TRANSMISSION
Minimum once a year, or if needed, check the tension of
the V-belt (8) (Fig.2). The belt must be pressed with one
hand in the middle of its length (Fig.3), and its bending
should amount to 1.5-2 cm. If the bending is significantly
different from the one stated above, adjust it by means of a
screw (7).

The burner may be cleaned and maintained by a qualified
employee of an authorised technical service exclusively.
Therefore, turn to the authorised technical service if help is
needed.

The heater may be moved by means of a pallet truck or a
forklift truck. The truck must be placed under the heater in
such a way as to distribute the weight of the heater evenly.
Make sure that the device, by means of which the heater is
to be lifted, is adjusted to such weight (the accurate weight
is given in the technical specification).
WARNING

disconnect it from power supply, disconnect the fuel
installation discharging the exhaust fumes and
distributing the air. Do not ever touch, transfer or
