SAFETY TEST - WITH GAS SUPPLY
CLOSED
For a safe start up it is very important to check
that the electrical wiring between the gas valves
and the burner has been carried out correctly.
To this end, after checking that the wiring has
been carried out in conformity with the burner's
wiring diagrams, a starting cycle must be carried
out with the gas tap closed (dry test).
1 The manual gas valve should be closed with
the locking/releasing device ("lock-out / tag
out" procedure).
2 Make sure the limit electric contacts of the
burner close
3 Make sure that the minimum gas pressure
switch contact closes
4 Proceed with a burner start up attempt.
The starting cycle should take place with the fol-
lowing phases:
- Starting of the fan motor for the pre-purging
- Control of the gas valve leak detection, if ap-
plicable.
- Completion of the pre-purging
- Attainment of the ignition point
- Power supply to the ignition transformer
- Power supply to the gas valves.
Since the gas is closed, the burner will not be
able to start and its control box will stop or safely
lockout.
The effective powering of the gas valves can be
verified with the insertion of a tester; some
valves have indicator lights (or opening/closing
position indicators) that are activated when they
are powered.
IF THE ELECTRICAL SUPPLY
TO THE GAS VALVES OCCURS
AT UNEXPECTED TIMES, DO
NOT OPEN
WARNING
VALVE, DISABLE
ELECTRICAL SUPPLY, CHECK
THE WIRING; CORRECT THE
ERRORS AND CARRY OUT THE
ENTIRE TEST AGAIN.
