TROUBLESHOOTING

POSSIBLE CAUSE
1. Propane/LP supply valve closed
on propane/LP cylinder
2. Blockage in burner/orifice
elbow/hose and regulator as-
sembly
3. Piezo ignition system not
sparking
1. Not enough warm-up time
2. Low gas pressure
3. Thermocouple loose or needs
to be replaced
4. Automatic control valve needs
to be replaced
5. Thermocouple gap is too
great.
1. Low gas pressure
2. Low fuel supply
3. Restriction in burner/orifice
elbow/hose and regulator as-
sembly

REMEDY
1. Open propane/LP supply
valve slowly
2. Clean burner/replace orifice
elbow/hose and regulator as-
sembly
3. Verify ignitor electrode gap is
.20". Check wire lead for dam-
age. Replace piezo ignitor and/or
ignitor electrode as necessary
1. Relight, hold automatic control
valve button in 30 seconds
2. Check propane/LP cylinder
for proper gas supply
3. Tighten connection or replace
thermocouple
4. Replace automatic control
valve assembly
5. Tip of thermocouple should
just touch the emitter material.
Loosen bracket screws to move
thermocouple closer to burner.
Be careful not to allow ignitor
to touch. Maintain 0.20"
1. Check gas supply; check
regulator output
2. Consult propane/LP gas supplier
3. Clean burner/replace orifice
elbow/hose and regulator as-
sembly
