The gas combustion system should be checked at
least once a year by a representative of the man-
ufacturer or another specialised technician.
Safety test - with gas ball valve closed
It is fundamental to ensure the correct execution of the electrical
connections between the gas solenoid valves and the burner to
perform safely the commissioning.
For this purpose, after checking that the connections have been
carried out in accordance with the burner's electrical diagrams,
an ignition cycle with closed gas ball valve -dry test- must be per-
formed.
1 The manual ball gas valve must be closed
2 The electrical contacts of the burner limit switch need to be
closed
3 Ensures closed the contact of the low gas pressure switch
4 Make a trial for burner ignition
The start-up cycle must be as follows:
– starting the fan for pre-ventilation
– Performing the gas valve seal control, if provided
– Completion of pre-ventilation
– Arrival of the ignition point
– Power supply of the ignition transformer
– Electrical Supply of solenoid gas valves
Since the manual gas ball valve is closed, the burner will not light
up and its control box will go to a safety lockout condition.
The actual electrical supply of the solenoid gas valves can be ver-
ified by inserting a tester. Some valves are equipped with light
signals (or close/open position indicator) that turn on at the same
time as their power supply.
IF THE ELECTRICAL SUPPLY OF THE GAS
VALVES OCCURS AT UNEXPECTED TIMES,
DO NOT OPEN MANUAL GAS BALL VALVE,
SWITCH OFF POWER LINE; CHECK THE
ATTENZIONE
WIRES; CORRECT THE ERRORS AND RE-
PEAT THE COMPLETE TEST.
