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.
B. Pilot orifice plugged.
C. Defective or misaligned
electrode at pilot.
D. Defective igniter.
E. After sitting for "off"
season (summer), pilot
assembly may be dirty.
A. Using the piezo sparker, try to light the pilot. If it will not
light, check the inlet gas pressure.
B. Clean or replace the pilot assembly.
C. If a match lights a pilot, check the electrode gap and
location. Should be a 1/8" gap in the flame area.
D. Check for a good connection between igniter and
electrode. Check wire insulation. If properly connected and no
spark, replace igniter.
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
B. Faulty connections.
C. Defective thermocouple.
D. Pilot dirty or plugged.
A. Check for proper inlet pressure for the gas being used.
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.
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. Clean or replace the pilot assembly.
