(Fig. 20)
READ THE WARNINGS CAREFULLY
AND FOLLOW THE RECOMMENDA-
TIONS CONTAINED IN THIS INSTRUC-
TION MANUAL WHEN USING THE
PRODUCT.
THE FIRST START-UP MUST BE CON-
DUCTED BY AN AUTHORISED TECH-
NICIAN OR BY THE AUTHORISED
TECHNICAL SUPPORT CENTRE.
••IMPORTANT: Before the first ignition,
make sure there are no packaging resi-
dues or accessories inside the heater.
••IMPORTANT: Before turning on the prod-
uct, make sure the heater is installed cor-
rectly (the gas connection, inlet pressure
and electrical connection must comply with
current regulations and match the values
declared on the data plate). Also ensure
there are no obstructions in the air circuit.
••IMPORTANT: During the first start-up,
use an approved device to check for any
leaks due to incorrect tightening or dam-
age to the gas supply circuit.
The heater can operate either in ventilation
or heating mode. To start the ventilating
mode, set the button to the "FAN" position
(Fig. 21). This way the heater only starts
the motor and keeps the gas circuit closed.
If you want to start the heating mode, set
the button to the "FLAME" position (Fig.
22). The heater opens the gas circuit and
starts the spark - thereby starting the com-
bustion - only after activating just the fan
to ensure the prewash of the combustion
chamber for around 30 seconds.
If the ignition fails more than 3 times, the
heater is blocked. To reset the heater, set
the start button to "O" (Fig. 23). A preven-
tive analysis of potential causes is briefly
reported in the anomalies table (Paragraph
on "Troubleshooting").
CAUTION: IF THE IGNITION FAILS
MORE THAN THREE TIMES, THE REA-
SON NEEDS TO THE CHECKED VIA
THE AUTHORISED TECHNICAL SUP-
PORT CENTRE.

the heater's operation (Fig. 25):

mally.
•LIGHT ON: This means the heater is
blocked.
►►12.TURNING OFF THE HEATER
To turn off the heater, set the button to the
"O" position (Fig. 23).
CAUTION: WHEN THE PUSHBUTTON
IS IN POSITION "O", THE HEATER IS
