TROUBLESHOOTING

STANDING PILOT IGNITION
SYMPTOM
1. Spark ignitor will
not light pilot.
2. Pilot will not
stay lit after
carefully following
lighting
instructions.
3. Pilot burning,
valve knob
turned to
"ON", switch
is turned to
"ON" or "RS",
but burner will
not ignite.
replace pilot
assembly.
POSSIBLE CAUSE
A. Wire disconnected.
B. Defective ignitor.
C. No gas or low gas
pressure.
D. Batteries not fitted or
batteries flat.
A. Defective
thermocouple
B. Defective valve
A. Defective switch,
wall switch,
remote control or
wire
B. Pilot flame too
small
C. Defective or
malfunctioning
thermopile
D. Defective valve
ACTION
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 pressure
can be caused by bent lines, restricted
lines, low pressure line
pressure. Consult with plumber or gas
supplier.
Check battery box.
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.
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 connections
are bad. Replace wire.
B. If pilot flame is not close enough
