OPERATING DESCRIPTION
If when the main switch is turned on, the thermostats are on, the
voltage 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.
TWO-STAGE OPERATION
The gas train supplied with the burner is composed of an ON/OFF
safety valve and a single stage slow opening main 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.
The gas flow adjustment in the first and second stage is carried
out by a streamlined valve activated by the electric servomotor (9).
The movement of the air damper (10) is caused by the rotation of
the servomotor (9) through the lever and return system (11).
For the adjustment of the air damper position according to the
power burned in the first and second stage, consult section
“Ignition and adjustment”.
If when the main switch is turned on, the thermostats are on, the
voltage reaches the control box which starts the burner.
This turns on the fan motor for pre-ventilating the combustion
chamber.
At the same time the rotation of the command servomotor (9)
occurs which activates the gas throttle and the air damper, through
the action of leverage (11), in the opening position corresponding
to the second stage.
The pre-ventilation phase comes only with the air damper in the
second stage position.
At the end of the pre-ventilation phase, the gas throttle and the air
damper are returned to the first stage position, then the ignition
transformer comes on and, 2 seconds later, the gas valves open.
The presence of the flame, detected by the control device, permits
continuation and completion of ignition, turning off the ignition
transformer.
Then passing on to the second stage of power through the
progressive opening of the gas throttle and the air damper at the
same time.
At the moment in which the demand for heat from the system is
satisfied, the boiler thermostat will intervene and shut down the
burner.
The air damper, through the rotation of the servomotor, will reach
the closed position when inactive.
In the event that the control device does not detect the presence
of a flame, the control box activates a “safety shut down” within 3
seconds of the opening of the main gas valve.
In “safety lock-out” mode the valves are closed again immediately.
To release the appliance from safety lock-out mode, press button
Reset button on the electrical panel.
