Symptom
Possible Cause
Corrective Action
1. Pilot will not
light.
A. Insufficient gas pressure,
air in the pilot line, or dirty or
kinked gas line.
A. Using the piezo sparker, try to light the pilot. If it will
not light, check the inlet gas pressure.
B. Pilot orifice plugged.
B. Clean or replace the pilot assembly.
C. Defective or misaligned
electrode at pilot.
C. If a match lights a pilot, check the electrode gap and
location. Should be a 1/8" gap in the flame area.
D. Defective igniter.
D. Check for a good connection between igniter and
electrode. Check wire insulation. If properly connected
and no spark, replace igniter.
E. After sitting for "off"
season (summer), pilot
assembly may be dirty.
E. Clean or replace the pilot assembly.
2. Pilot will not stay
lit after carefully
following lighting
instructions.
A. Low or too high gas
pressure
A. Check for proper inlet pressure for the gas being
used.
B. Faulty connections.
B. Measure voltage between valve body and solder
connection on the rear of the valve (where the blue wire
connects). It should be no less than 7 mV.
C. Defective thermocouple. C1. Ensure that the thermocouple connection at the gas
valve is tight.
C2. Check thermocouple output using milli-volt meter.
Disconnect from valve and read voltage across wire
ends. If the reading is less than 15 mV, replace the pilot
assembly.
C3. If burning NG, check pilot flame to see that it is
impinging on the top of the thermocouple. Clean or
replace pilot for maximum flame impingement.
D. Pilot dirty or plugged.
D. Clean or replace the pilot assembly.
