CONSUMER INSTRUCTIONS
? Keep the area around the burner clear and free of combustible material, gasoline or other
flammable liquids or vapors. Do not obstruct burner air openings or ventilation grills for
combustion air.
? After 3 years of normal service, the motor bearings need to be reoiled annually with 10 drops
of 5W30 oil.
WARNING: If any flame is observed when the burner is on standby, or if the ignition
spark or valve operator is heard to come on before the motor reaches operating speed,
immediately turn off the manual gas control and burner power. A dangerous condition
has developed and must be corrected. CONTACT A QUALIFIED SERVICE TECHNICIAN
FOR CLEANING, READJUSTMENT OR REPAIR.
? Check that the ignition spark does not come on before the motor reaches operating speed.
If it does, the air switch is defective and must be replaced. (See Section X, Motor / Blower
Interlock).

TROUBLE CHART
Make sure the thermostat and operating controls are calling for heat. Defective wiring or loose
connections can simulate the component defects outlined below. Check associated wiring before
replacing a component.
ELECTRICAL AND FLAME CHECKS MUST BE MADE IN ORDER LISTED.
I Confirm 120V between strip terminals 1 and 2 and verify the circuit polarity and electrical
ground, between strip terminal 1 and burner chassis metal.
II A. Confirm that both Main Manual Shut-Off Valve and Manual Gas Cock Knob on
Combination Gas Valve are in the ON position.
B. Whenever the burner fails to light during the 6-second trial for ignition, or if the flame is lost
during the burner run and not re-established within 36 seconds the Electronic Control will
shut off the Combination Valve and LOCK OUT. To RESET the Control for restart, set
the operating control to OFF or thermostat below room temperature for at least 30
seconds.
1. Check for 24V* between strip terminal GND and Electronic Control 25V terminal. No
voltage, blower interlock circuit is defective.
2. If Electronic Control has a fuse, test for 24V from each end of fuse to strip terminal
GND.
C. For each of the following tests, reset the Electronic Control per step II.B. TESTS ARE
VALID ONLY DURING THE 6 SECOND TRIAL FOR IGNITION.
1. Turn Manual Gas Cock Knob to Off. Check for 24V between the Electronic Control
