OBSERVED PROBLEM

POSSIBLE CAUSE

REMEDY

Pilot goes out when wall switch is ON

1. Millivolt output on thermopile too high

1. Replace thermopile

 

 

 

Spark ignitor will not light pilot after re- peated triggering of red button

1.Defective ignitor (no spark at electrode)

2.Defective pilot or misaligned electrode at pilot (spark at electrode)

3. No gas or low gas pressure

4.If using propane/LP gas, no propane/LP gas in tank

1.Check for spark at the electrode and pi- lot; if no spark and electrode wire is properly connected, replace ignitor

2.Using a match, light pilot. If pilot lights, turn off pilot and trigger the red button again. If pilot lights, an improper gas/air mixture caused the improper lighting and a longer purge period is recommended. If pilot will not light, check gap at electrode and pilot. Gap should be 1/8" to have a strong spark. If okay, replace pilot

3.A) Check remote shut off valves from fireplace. Usually there is a valve near the fireplace and sometimes there is a valve near the main. There can be more than one (1) valve be- tween the fireplace and main

B)Low pressure can be caused by a va- riety of situations such as bent line, too narrow diameter of pipe, or even low line pressure. Check for kinked lines. If none, consult with plumber or gas supplier

4.Check propane/LP supply and contact local propane/LP supplier
