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,”

jumper wires across terminals of switch. If burner comes

 

switch is turned to

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 all

are tight and that the thermopile is fully inserted into

ing thermopile

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 read-

ing 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.
