BURNER OPERATION

BURNER STARTING (A)
Starting phases with progressive time intervals
shown in seconds:
- Control device TL closes.
After about 3s:
- 0 s : The control box starting cycle begins.
- 2 s : The fan motor starts.
- 3 s : The ignition transformer is connected.
The pump sucks the fuel from the tank
through the piping and the filter and pumps it
under pressure to delivery. The piston rises
and the fuel returns to the tank through the
piping. The screw closes the by-pass heading
towards suction and the solenoid valves, de-
energized, close the passage to the nozzles.
- 5 s: The servomotor opens the air gate valve:
pre-purging begins with the 1st stage air
delivery.
- 26 s : The solenoid valves open 8); and the
fuel passes through the piping 12) and filter
13) and is then sprayed out through the noz-
zle, igniting when it comes into contact with
the spark. This is the 1st stage flame.
- 32 s: The ignition transformer switches off.
- 33 s: If the control device TR is closed or has
been replaced by a jumper wire, the servomo-
tor opens the fan air gate valve in the 2nd
stage.
- 35 s: The 2nd stage solenoid valve is
opened. The starting cycle comes to an end.
