pilot.
a. Ignitor electrode positioned wrong - Replace pilot.
b. Ignitor electrode is broken - Replace pilot.
c. Ignitor electrode not connected to ignitor cable - Reconnect
ignitor cable.
d. Ignitor cable pinched or wet. Keep ignitor cable dry - Free

c. ODS/pilot is partially clogged - Clean ODS/pilot.
d. Defective thermocouple - Replace pilot.
4. Appliance shuts off during use. (Pilot stays on.)

connections, output should be a minimum of 325 millivolts
across. TH/TP and TP terminals with REMOTE/OFF/ON
switch off.
5. Gas odor even when control knob is in OFF position.
a. Gas leak - Locate and correct all leaks.
b. Control valve defective - Replace control valve.

tighten until snug, then tighten 1/4 turn more.
e. Pilot ame not touching thermocouple, which allows
thermocouple to cool, causing pilot ame to go out. This
problem could be caused by either low gas pressure or dirty or
partially clogged ODS/pilot - Contact local gas company.
f. Thermocouple damaged - Replace thermocouple.
g. Control valve damaged - Replace control valve.
8. Burner does not light after ODS/pilot is lit.
a. Burner orice clogged - Clean burner or replace main burner
