10. Troubleshooting

low-fire.
1. Check the gas pressure reading on the gauge. Problem may be
due to insufficient gas regulator setting. Temporarily decrease
the High-Low Fire thermostat setting to verify that the
thermostat will function and cause the burner to cycle. If burner
will cycle at the reduced thermostat setting, it indicates that the
problem was due to insufficient heat to satisfy the original
setting. Increase the gas regulator setting for additional
heat output. Do not exceed the maximum pressure listed in
this manual.

2. High-Low Fire thermostat control may be defective. If the burner
still does not cycle to low-fire after decreasing the thermostat,
the problem may be due to a broken or kinked thermostat
sensor tube. Observe reading on the thermometer. Replace
control assembly if it cannot be set to cause its switch to go
to the open circuit position with normally hot air plenum
temperatures.

3. If the burner continues to operate on high-fire, check the
high-fire gas solenoid valve for a stuck or blocked open
condition, or for reversed gas pipe connections. The solenoid
valve must not allow gas flow when its coil is not energized.

1. Check for an excessive low-fire gas pressure setting. Observe
pressure setting shown on gauge, and compare reading with
recommended low pressure settings listed in this manual.

2. Check for improperly adjusted or defective High-Low Fire
thermostat control. Temporarily increase the temperature
setting. If the heater will still not cycle, check for problem in the
control wire connections. The control wires should be connected
to terminals R and B of the thermostat, so the switch will open
upon temperature rise. If the burner will cycle with these two
wires connected together, the thermostat is faulty.

3. Check for improperly connected or faulty high-fire gas vapor
solenoid valve. Correct any poor connections or defective
wiring. If wiring appears proper, problem may be caused by a
burned out valve coil or defective valve. Replace high-fire
solenoid valve, or its coil, if defective.
