TROUBLESHOOTING
STANDING PILOT IGNITION
SYMPTOM
1. Spark igniter
will not light pi-
lot after repeat-
ed triggering of
piezo.
2. Pilot will not
stay lit after
carefully fol-
lowing lighting
instructions.
3. Pilot burning,
valve knob
tuned to “ON”,
switch is turned
to “ON” or “RS”,
but burner will
not ignite.
4. Frequent pilot
outage prob-
lem.
5. The pilot and
main burner
extinguish while
in operation.
POSSIBLE CAUSE
A. Wire disonnected.
B. Defective igniter.
C. No gas or low gas
pressure.
D. No Propane/LPG in
tank.
A. Defective thermocou-
ple.
B. Defective valve.
A. Defective switch, wall
switch, remote control
or wire.
B. Pilot flame too small.
C. Defective or malfunc-
tioning thermopile.
D. Defective valve.
A. Pilot flame may be too
high or too low, caus-
ing pilot safety to drop
out.
A. Inner vent pipe leaking
exhaust gases back
into system.
B. Horizontal vent improp-
erly pitched.
C. Improper vent cap
installation.
ACTION
A. Open door and check to make sure wire is connected to
igniter.
B. Check for spark at electrode and pilot. If no spark and elec-
trode wire is properly connected, replace pilot assembly.
C. Check remote/manual shut-off valve from fireplace. Low
pressure 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.
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 mil-
livolt 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 15m V, replace pilot assembly.
B. If thermocouple is producing more than 15m V, replace faulty
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 proce-
dure on remote control. If burner comes on, replace remote
control. Place jumper wire across wire at gas valves (termi-
nals marked TH and TP/TH). If burner comes on, wires are
faulty or connections 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 325m V, 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 me-
ter reads greater than 175m V and the burner does not light,
replace defective valve.
A. Clean and adjust the pilot flame for maximum flame impinge-
ment on thermocouple.
A. Check for flue product leak. Replace defective pipe section.
B. Check horizontal-vent 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
blockage.
