Standing Pilot Ignition

 

SYMPTOM

POSSIBLE CAUSE

ACTION

 

 

 

 

1.

Spark ignitor will

A. Wire disconnected.

A. Open door and check to make sure wire is connected

 

not light pilot after

 

to ignitor.

 

repeated triggering of

B. Defective ignitor.

B. Check for spark at electrode and pilot. If no spark and

 

piezo.

 

electrode wire is properly connected, replace pilot

 

 

 

assembly.

 

 

C. No gas or low gas pres-

C. Check remote/manual shut off valve from fireplace.

 

 

sure.

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

D. Check Propane/LPG tank. Refill tank.

 

 

 

2. Pilot will not stay lit

A. Defective thermocouple

A. Check that thermocouple flame impinges on thermo-

 

after carefully follow-

 

couple. Clean and/or adjust pilot for maximum flame

 

ing lighting instruc-

 

impingement. Ensure that the thermocouple connec-

 

tions.

 

tion 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. Defective valve

B. If thermocouple is producing more than 15 mV,

 

 

 

replace faulty valve.

 

 

 

 

3.

Pilot burning, valve

A. Defective switch, wall

A. Check switch and wire for proper connection. Place

 

knob turned to “ON”,

switch, remote control or

jumper wires across terminals of switch. If burner

 

switch is turned to

wire

comes on, replace defective switch.If the switch is OK,

 

“ON” or “RS”, but

 

repeat the same procedure on remote control If burner

 

burner will not ignite.

 

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

B. If pilot flame is not close enough to the thermopile,

 

 

 

adjust pilot flame.

 

 

C. Defective or malfunction-

C. Check thermopile wire connections to make sure

 

 

ing thermopile

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

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.
