TROUBLESHOOTING
STANDING PILOT - MILLIVOLT
SYMPTOM POSSIBLE CAUSE REMEDY
1. Spark ignitor will
not light pilot after
repeated triggering
of piezo.
A. Wire disconnected. Open door and check to make sure wire is connected to
ignitor.
B. Defective ignitor. Check for spark at electrode and pilot. If no spark and
electrode wire is properly connected, replace pilot assembly.
C. No gas or low gas
pressure.
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. No Propane/LPG in
tank
Check Propane/LPG tank. Refill tank
2. Pilot will not stay
lit after carefully
following lighting
instructions.
A. Defective Valve If thermopile is producing more than 325 mV, replace faulty
valve.
3. Pilot burning, 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
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 connections are bad. Replace wire.
B. Pilot flame too small If pilot flame is not close enough to the thermopile, adjust
pilot flame.
C. Defective or
malfunctioning
thermopile
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. Defective valve 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 100 mV and the burner does
not light, replace defective valve
4. Frequent pilot
outage problem.
A. Pilot flame may be
too high or too low,
causing pilot safety to
drop out
Clean and adjust the pilot flame for maximum flame
impingement on thermopile.
