Problem
Possible Cause
Corrective Action
When ignitor button is
pressed in there is a
spark at ODS/pilot but
no ignition.
1. Gas supply is turned off or
equipment shutoff valve is
closed.
2. Control knob not fully
pressed in while pressing
ignitor button.
3. Air in gas lines (new instal-
lation or recent gas interrup-
tion).
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. Turn on gas supply or open
equipment shutoff valve.
2. Fully press in control knob
while pressing ignitor button.
3. Continue holding down con-
trol knob. Repeat igniting op-
eration until air is removed.
4.
Clean ODS/pilot (see
Care
and Maintenance
, page 21) or
replace ODS/pilot assembly.
5. Check inlet gas pressure or
replace inlet gas regulator.
6. Turn control knob to PILOT
position.
7. Contact local propane/LP
gas company.
ODS/pilot lights but flame
goes out when control
knob is released.
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
problem could be caused by
one or both of the following:
A) Low gas pressure
B) Dirty or partially clogged
ODS/pilot
6. Thermocouple damaged.
7. Control valve damaged.
1. Press in control knob fully.
2. After ODS/pilot lights, keep
control knob pressed in 30

pilot assembly
6. Replace thermocouple.
7. Replace control valve.
Burner(s) does not light
after ODS/pilot is lit
1. Burner orifice is clogged.
2. Burner orifice diameter is too
small.
3. Inlet gas pressure is too low.
1. Clean burner orifice (see
Care and Maintenance
,
page 21) or replace burner
orifice.
2. Replace burner orifice.
3. Contact local gas supplier.
Delayed ignition of
burner(s).
1. Manifold pressure is too low.
2. Burner orifice is clogged.
1. Contact local gas supplier.
2. Clean burner (see
