OPERATING DESCRIPTION
The gas train supplied is composed of an ON/OFF safety valve and a
single stage slow opening main valve.
The fuel flow rate regulation in the first and second stage is carried out
by a streamlined throttle valve -6, activated by the electric servomotor
-7.
The movement of the air shutter is produced by the rotation of the
servomotor -7 through the -34 lever and tie rods.
For the adjustment of the air damper position according to the power
burned in the first and second stage, consult section: “Starting up and
adjustment”.
If when the main switch -1 is closed, the thermostats are closed, the
voltage reaches the command and control equipment which starts
the burner -2.
This turns on the fan motor for preventilation of the combustion
chamber.
At the same time the rotation of the command servomotor -7 which
brings the gas throttle -6 and the air gate -8, through the action of
leverage, in the opening position corresponding to the second flame.
The preventilation phase comes only with the air gate in the second
flame position.
At the end of pre-ventilation, the gas throttle and the air shutter are
returned to the ignition position, then the ignition transformer turns on
and 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 gate 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 boiler.
The air shutter, 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” -10 within three
seconds of the opening of the main gas valve. In “safety lock-out”
mode the valves are closed again immediately.
To release the equipment from its safety position, press the release
button -10
