OPERATING DESCRIPTION

stage
peratIon
If when the main switch is turned on, the thermostats are on, the volta-
ge reaches the control box which starts the burner.
This turns on the fan motor for pre-ventilating the combustion chamber.
The ignition transformer then comes on, and 2 seconds later the gas
valves open.
The main valve, which has two stages, has a device for adjusting gas
delivery for the first and second flame.The safety valve is an ON/OFF
valve.
IMPORTANT
In some particular applications, in the event that there are
pulsations in the flame during the functioning of the burner with
natural gas, it is advisable to use the intended reducers for LPG
fuel.
As the burner is ON/OFF, the position of the air lock must be regulated
for operation at maximum capacity.
Combustion air may be adjusted manually using the air damper (see
paragraph entitled "Diagram for air adjustment in single-stage burner").
The presence of the flame, detected by the control device, permits con-
tinuation and completion of ignition, turning off the ignition transformer.
In "safety lock-out" mode the valves are closed again immediately.
To release the appliance from safety lock-out mode, press button
Unlock button on the electrical panel.
