1. Ignitor electrode is posi-
tioned wrong. Ignitor elec-
trode is broken.
2. Ignitor electrode is not con-
nected to ignitor cable.
3. Ignitor cable is pinched or
wet.
4 Broken ignitor cable.
5. Bad piezo ignitor.
1. Gas supply is turned off or
equipment shutoff valve is
closed.
2. C o n t r o l k n o b n o t f u l l y
pressed in while pressing
ignitor button.
3. Air in gas lines when in-
stalled.
4. ODS / pilot is clogged.
5. Incorrect inlet gas pressure
or inlet regulator is damaged.
6. Control knob not in PILOT
position.
7. Depleted gas supply (pro-
pane).
1. Control knob is not fully
pressed in.
2. Control knob is not pressed
in long enough.
3. Equipment shutoff valve is
not fully open.
4. Thermocouple connection is
loose at control valve.
5. Pilot flame not touching
thermocouple, which allows
thermocouple to cool, caus-
ing pilot flame to go out. This

one or both of the following:
A) Low gas pressure
B) Dirty or partially clogged
ODS/pilot
6. Thermocouple damaged.
