OPERATING DESCRIPTION
The gas train supplied is composed of an ON/OFF safety valve and a
single stage slow opening main valve.
At the end of pre-ventilation, the gas throttle and the air damper are
returned to the ignition position, then the ignition transformer turns on
and the gas valves open.
Then passing on to the second stage of power through the progres-
sive 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 sa-
tisfied, the boiler thermostat will intervene and shut down the boiler.
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” (4)(H2) within 3
seconds from 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)(S2)
