WINTER OPERATION (HEATING)
To Have: the heater connected to the gas and power supply lines.
1 - Set the room thermostat to the maximum value.
2 - Open the main gas cock.
3 - Power the appliance by closing the 2-pole switch (to be supplied by the electrical
installation technician).
4 - Set the winter/summer key (A) of the remote control to the winter (
) position (see
Figure 2 at page 13).
5 - After the pre-purge time (about 40 seconds), the gas solenoid valve opens and the
heater is turned on.
6 - If the flame is present, the control box keeps the gas valve open.
7 - Otherwise, the flame control box locks out the appliance by switching on the lock out
warning light C on the reset button B (see Figure 2 at page 13).

If the heater is switched on after a long period of inactivity or at the first start-up of
the appliance you may need to repeat several times the operation because there is
air in the pipes.
