NATURAL GAS IGNITION AND
REGULATION
•
Check that there is water in the boiler and that the gate valves
of the system are open.
•
Make sure that the combustion products may be freely vented
through the boiler and flue dampers.
Check that all the gate valves fitted on the fuel pipes are open; the
same applies to any other fuel shut-off devices.
•
Adjust the air for the ignition flame:
• Make sure that the fan motor rotates in the correct direction.
Carry out a check of the equipment before commissioning, after
each overhaul and after the equipment has been inactive for a
long time.
Verify the combustion chamber does not contain gas before any
ignition operation.
• Attempting a start up without introducing gas, verify a lock
out stop occurs at the end of the safety time (or more cycle
repetitions up to a maximum of 10, depending on the settings).
•
Interrupting the flow of gas with the equipment operating, verify
that voltage to the gas solenoid valves is cut within 1 sec., and
after a cycle repetition (or more repetitions up to a maximum
of 10, depending on the settings), the equipment carries out a
lock out stop.
