STARTING PROCEDURES
1) Preliminary operations
- Mount the pressure gauge and the vacuum gauge on the pump (remove after tune up).
- Open the fuel line valve.
- Close the thermostat lines (furnace/room temperature)
- Attach electricity to the main switch.
- Switch to the on position.
- Unlock the burner (by pushing the red button)
2) Starting cycle
F
- In-line filter
P
- Pump
VE1 - Electromagnetic valve 1° choke
VE2 - Electromagnetic valve 2° choke
G1
- 1° choke
G2
- 2° choke
A) After the preliminary operations, begin the starting cycle. The burner motor begins to rotate with the pump; The fuel
introduced is directed back to the tank. The burner ventilator and the ignition transformer are also in operation and
perform the phases of:
- pre-heating of the combustion chamber
- pre-cleaning a part of the fuel circuit
- pre-ignition with spark between the electrode points
N.B.: During pre-ventilation, the servomotor positions the butterfly valve with regards to the setting of the first flame.
B) At the end of the pre-cleaning, the burner opens the electromagnetic valve VE1; the fuel arrives to the choke G1 and
comes out finely atomised.
The contact with the spark present between the electrode points determines the ignition of the flame. The safety cut-off
time begins simultaneously.
