STANDING PILOT IGNITION
TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSE ACTION
1. Spark ignitor
will not light
pilot after
repeated trig-
gering of piezo.
A. Wire disconnected.
B. Defective ignitor.
C. No gas or low gas pressure.
D. No Propane/LPG in tank
A. Open door and check to make sure wire is connected to ignitor.
B. Check for spark at electrode and pilot. If no spark and electrode
wire is properly connected, replace pilot assembly.
C. Check remote/manual shut off valve from fireplace. Low pres-
sure can be caused by bent lines, restricted lines, low pressure
line pressure. Consult with plumber or gas supplier.
D. Check Propane/LPG tank. Refill tank.
2. Pilot will not
stay lit after
carefully fol-
lowing lighting
instructions.
A. Defective thermocouple
B. Defective valve
A. Check that thermocouple flame impinges on thermocouple.
Clean and/or adjust pilot for maximum flame impingement.
Ensure that the thermocouple connection at the gas valve is fully
inserted and tight.
Disconnect the thermocouple from the valve, place one millivolt
lead wire on the tip of the thermocouple and the other meter lead
wire on the thermocouple copper lead. Start the pilot and hold
the valve knob in. If the millivolt reading is less than 15 mV,
replace pilot assembly.
B. If thermocouple is producing more than 15 mV, replace faulty
valve.
3. Pilot burn-
ing, valve
knob turned to
“ON”, switch
is turned to
“ON” or “RS”,
but burner will
not ignite.
A. Defective switch, wall switch,
remote control or wire
B. Pilot flame too small
C. Defective or malfunctioning ther-
mopile
D. Defective valve
A. Check switch and wire for proper connection. Place jumper
wires across terminals of switch. If burner comes on, replace
defective switch.If the switch is OK, repeat the same procedure
on remote control If burner comes on, replace remote control.
Place jumper wire across wire at gas valves (terminals marked
TH and TP/TH). If burner comes on, wires are faulty or connec-
tions are bad. Replace wire.
B. If pilot flame is not close enough to the thermopile, adjust pilot
flame.
C. Check thermopile wire connections to make sure all are tight
and that the thermopile is fully inserted into pilot assembly.
Check thermopile with a millivolt meter. Connect leads to TP
and TP/TH terminals on the control valve. If meter reading is
below 325 mV, replace pilot assembly.
D. Turn valve knob to “On” and switch to “ON.” Take a reading at
the thermopile leads (TP & TP/TH) on the valve. If the meter
reads greater than 175 mV and the burner does not light, replace
defective valve
4. Frequent pilot
outage prob-
lem.
A. Pilot flame may be too high or too
low, causing pilot safety to drop
out
A. Clean and adjust the pilot flame for maximum flame impinge-
ment on thermocouple.
5. The pilot and
main burner
extinguish
while in opera-
tion
A. Inner vent pipe leaking exhaust
gases back into system
B. Horizontal vent improperly
pitched
C. Improper vent cap installation
A. Check for flue product leak. Replace defective pipe section.
B. Check horizontal-venting piping is running upward 1/4" per
foot. Do not run the pipe level or downward.
C. Check for proper installation and freedom from debris or block-
age.
