ADJUSTMENT AND CHECKOUT
IMPORTANT
Adjustments should be made by qualified personel
only.
If the appliance manufacturer supplies checkout
and/or service and maintenance instructions,
carefully follow them.
Light pilot flame
· Before lighting pilot flame, turn thermostat to the lowest
setting.
· Shut off gas supply to the main and pilot burner.
CAUTION
Wait 5 minutes to allow complete venting of any
unburned gas.
Remember LP gas is heavier than air and will not
vent upwards.
· Turn on gas supply and light pilot flame according to the
appliance manufacturer's instructions.
· Pilot flame should burn with a steady blue flame.
Pilot flame adjustment
Adjust pilot flow adjustment screw to give a soft, steady flame
enveloping the thermocouple tip.
Test for gas leakage
Paint all joints with a rich soap and water solution. Take care
not to use an agressive soap. Bubbles indicate leak. To stop
leak, tighten joint or make a new one and check again.
Never use a flame to check for gas leakage.
Checkout main burner ignition
WARNING
This test should be performed only after main burner
gas input adjustments have been made.
Pilot burner should ignite main burner quietly and reliable
under all operating conditions, including low gas supply
pressure.
Pilot flame must not smother or snuff out when tested as
follows:
· Main burner ignition from cold--start--repeat.
· Continuous operation of main burner.
· Main burner ignition with appliance at maximum operating
temperature after prolonged operation.
Checkout
Before leaving, set appliance in operation and observe
through several cycles to ensure that burner system
components function correctly.
TROUBLESHOOTING
Pilot outage
If pilot flame is correctly adjusted but extinguishes during
normal operation, recheck Mounting and Location.
It may be necessary to construct a shield to protect pilot flame
against draughts and main burner ignition/extinction.
