GENERAL INSTRUCTIONS FOR SERVICING BURNER
Gas burners require the services of an experienced technician for proper setting and adjustment. If the burner does
not appear to be operating properly, DO NOT ATTEMPT TO ADJUST THE BURNER YOURSELF, but call in a
competent serviceman. An OEM should be able to check several possible causes of shutdown before calling in a
serviceman. The following check list may eliminate the need for a service call or at least provide information for the
serviceman.
1. Check thermostat. Make sure that it is set at the desired temperature.
2. Check fuses in service box for the burner circuit. Replaceable type fuses should not be loose in the socket. If a
fuse is blown out or if in doubt, replace with the same size and type. If circuit breaker is in the service box, check
position of indicator. If tripped, reset.
3. Check on-off switch for the burner circuit, it may have been accidentally turned off.
4. With the thermostat set 10 degrees above room temperature, the burner should start automatically.
It is advisable, periodically, to visually inspect the burner. Check air inlet blower to make sure it is not
clogged or blocked. Check air shutter to make sure that it has not been tampered with, make sure that it is in
the same position as when final adjustments were made. Check blower wheel to see if it is dirty or full of lint.
If the flame does not appear normal or if in doubt, call a serviceman.
The areas around the burner should be kept
clear and free of combustible materials, gasoline and other flammable vapors and liquids. The flow of combustion and
ventilating air to the burner must not be blocked or obstructed in any manner.
CLEANING OF BURNERS (BY SERVICEMAN ONLY): Remove the burner from the appliance and visually inspect
the blast tube for any deterioration. Check thermo-couples, electrodes, etc. with illustrations in the owner’s manual for
