TROUBLESHOOTING
Note: All troubleshooting
items are listed in order of
operation.
WARNING: Only a qualified
service person should ser-
vice and repair heater.
CAUTION: Never use a wire,
needle, or similar object to
clean ODS/pilot. This can
damage ODS/pilot unit.
REMEDY
1. Replace ignitor.
2. Replace ignitor.
3. Reconnect ignitor cable.
4. Free ignitor cable if pinched
by any metal or tubing. Keep
ignitor cable dry.
5. Replace ignitor cable.
6. Replace control valve ( piezo
is part of control valve).
7. Tighten nut holding piezo
ignitor to base panel of log
set. Nut is located behind base
panel.
1. Turn on gas supply or open
equipment shutoff valve.
2. Fully press in control knob while
pressing ignitor button.
3. Continue holding down control
knob. Repeat igniting operation
until air is removed.
4. Clean ODS/pilot (see Cleaning
and Maintenance) or replace
ODS/pilot assembly.
5 . R e p l a c e g a s r e g u l a t o r
6. turn control knob to pilot
position.
7. Replace gas regulator.
1. Press in control knob fully.
2. After ODS/pilot lights, keep
control knob pressed in 30
seconds.
3. Wait one minute for safety
interlock system to reset.
Repeat ignition operation.
4. Fully open equipment shutoff
valve.
5. Hand tighten until snug, then
tighten 1/4 turn more.
6. A) Contact local natural or pro-
pane/LP gas company.
B) Clean ODS/pilot (see Cleaning
and Maintenance) or replace
ODS/pilot assembly.
7. Replace thermocouple.
8. Replace control valve.
POSSIBLE CAUSE
1. Ignitor electrode is positioned
wrong.
2. Ignitor electrode is broken.
3. Ignitor electrode is not connected
to ignitor cable.
4. Ignitor cable is pinched or wet.
5. Broken ignitor cable.
6. Bad piezo ignitor.
7. Piezo ignitor nut is loose.
1. Gas supply is turned off or
equipment shutoff valve is closed.
2. Control knob is not fully pressed in
while in PILOT position.
3. Air in gas lines when installed.
4. ODS/pilot is clogged.
5. Gas regulator setting is not correct.
6. Control knob not in PILOT position.
7. Depleted gas supply.
1. Control knob is not fully pressed in.
2. Control knob is not pressed in
long enough.
3. Safety interlock system has been
triggered.
4. Equipment shutoff valve is not
fully open.
5. Thermocouple connection is loose
at control valve.
6. Pilot flame is not touching
thermocouple, which allows
thermocouple to cool and 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.
7. Thermocouple damaged.
8. Control valve damaged.
OBSERVED PROBLEM
When ignitor button is pressed
in, there is no spark from ODS/
pilot.
ODS/pilot lights but flame goes
out when control knob is
released.
When ignitor button is pressed in,
there is a spark at ODS/pilot but
no ignition.
