impingement. Ensure that the thermocouple connection

 

tions.

 

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,”

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.
