C. Valve.

Turn the valve knob to the ON position. Place the ON/

 

 

OFF switch in the ON position. Take a reading with a

 

 

millivolt meter at the thermopile terminals. The millivolt

 

 

meter should read greater than 125mV. If the reading

 

 

is acceptable, and if the burner does not come on, re-

 

 

place the gas valve.

the wall switch. If the burner comes on, replace the

 

 

wall switch. If the wall switch is OK, place the jumper

 

 

wires across the wall switch wires at the gas valve. If

 

 

the burner comes on, the wires are faulty or connec-

 

 

tions are bad.
