• Check pilot for full flame impingement around 

thermocouple.  If flame is too small, check gas 

pressure, adjust pilot rate screw, check pilot head for 

damage or blockage.

• Check thermocouple voltage at rear of valve. It must 

be greater than 5 mV.  If low, replace thermocouple.

Air in gas line (pilot dies 

while knob is depressed).

• Bleed line.

• Check gas line pressure.

• Contact dealer.

lit

Problem with thermopile 

circuit.

• Check gas line pressure .

• Check for flame impingement on thermopile. If low, 

see “Pilot will not remain lit”.

burner is switched on.

• Check wiring to thermostat for breaks.

Flame lifting

Leak in vent pipe.
