VIII. TROUBLE SHOOTING
Cause
A. Defective ignitor.
B. Misaligned electrode.
C. No gas to
pilot/plugged orifice.
D. Ignitor wire grounding
out.
E. Loose ignitor wiring.
A. Pilot flame not in con-
stant contact with pilot
sensor.
B. Pilot sensor not tight-
ened/seated in valve
properly.
C. Defective pilot sensor
thermocouple.
D. Faulty valve.
A. 110 volts of electricity
has burned out valve.
B. "ON/OFF" switch
defective.
C. Plugged burner orifice.
D. Defective thermopile.
E. Burner not on orifice.
F. Loose or faulty wiring.
G. Faulty valve.
A. Intermittent short in
"ON/OFF" wiring sys-
tem.
B. Defective thermopile.
A. Pilot flame not in constant
contact with pilot sensor.
B. Defective pilot sensor
thermocouple.
A. Normal result of gas
combustion.
A. Normal result during first
20 minutes of burning.
A. Normal result during
initial few hours of
operation.
B. Improper log place-
ment causing soot.
C. Dark yellow tipped flame.
Corrective Action
Replace ignitor.
Spark should be approximately 1/8" to bottom of pilot hood. Adjust gap to give
proper spark. Remove hands from electrode before pressing red button.
Check valve knob position & any shut-off valves. If propane, check for empty
tank. Check pilot orifice; remove any blockage.
Replace pilot assembly.
Check for spark. If electrode connection is correct & no spark, replace ignitor.
Check log placement. Check pilot flame; adjust flame if necessary.
Check that pilot sensor connector is tight in valve.
Replace pilot sensor thermocouple.
Replace valve.
Remove voltage and replace valve.
Check "ON/OFF" switch for proper connections. Connect wires across terminal at
"ON/OFF" switch. If burner comes on, replace "ON/OFF" switch. If burner
doesn't come on, connect to "ON/OFF" switch junctions at valve. If burner comes
on, replace wires.
Check burner orifice, remove blockage.
Replace thermopile.
Check burner; place on orifice.
Check for loose connections; verify wiring. See Figures 16 and 17.
Replace valve.
Have a qualified service technician check venting system for blockage (i.e.
bird nests, damage). Ensure proper venting condition. Check/replace
"ON/OFF" wiring system.
Replace thermopile.
Check log placement; check pilot flame, adjust flame if necessary.
Replace pilot sensor thermocouple.
No action necessary - glass will clear as appliance warms.
No action necessary - flames will turn more yellow after about 20 minutes.
Clean glass with Brasso or silver polish.
Check log placement; reposition if necessary.
Open air shutter to increase air to gas ratio.
