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 ignitor cable if pinched by any metal or tubing.
e. Broken ignitor cable - Replace ignitor cable.
f. Bad piezo ignitor - Replace piezo ignitor.
 2. Applianceproducesunwantedodors.
a. Appliance burning vapors from paint, hair spray, glues,
etc. - Ventilate room. Stop using odor causing products
while heater is running.
b. Gas leak - Locate and correct all leaks.
 3. Applianceshutsoffduringuse.(Pilotandmainburner
areoff.)
a. Not enough fresh air is available for ODS/pilot to
operate - Open window and/or door for ventilation.
b. Low line pressure - Contact local gas company.
c. ODS/pilot is partially clogged - Clean ODS/pilot.
d. Defective thermocouple - Replace pilot.
 4. Applianceshutsoffduringuse.(Pilotstayson.)
a. Low line pressure - Check line pressure to the
valve.
b. Defective thermopile - Check pilot ame, check wire
connections, output should be a minimum of 325
millivolts across. TH/TP and TP terminals with ON/
OFF 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.
 6. When ignitor button is pressed, there is spark at
ODS/pilot,butnoignition.
a. Gas supply turned off or manual shutoff valve closed
- Turn on gas supply or open manual shutoff valve.
b. Control knob not in PILOT position - Turn control knob
to PILOT position.
c. Control knob not pressed in while in PILOT position
- Press in control knob while in PILOT position.
d. Air in gas lines when installed - Continue holding

c. Manual Shutoff valve not fully open - Fully open manual
shutoff valve.
d. Thermocouple connection loose at control valve - Hand
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 orice.
b. Burner orice diameter is too small - Replace burner
orice.
c. Inlet gas pressure is too low - Contact qualied service
person.
 9. If burning at main burner orice occurs (a loud,
roaringblowtorchnoise).
a. You must turn off burner assembly and contact a
qualied service person.
b. Manifold pressure is too low - Contact local gas
company.
c. Burner orice clogged - Clean burner or replace burner
orice.
10. Logsappeartosmokeafterinitialoperation.
a. Vapors from paint or curing process of logs - Problem
will stop after a few hours of operation. Run the heater

Log heater is intended to be smokeless. Turn OFF
heater and call qualied service person.
11. Heaterproducesawhistlingnoisewhenmainburner
islit.
a. Turning control knob to HIGH position when main
burner is cold - Turn control knob to LOW position
and let warm up for a minute.
b. Air in gas line - Operate burner until air is removed from
line. Have gas line checked by local gas company.
c. Dirty or partially clogged burner orice - Clean burner
or replace burner orice.
12. Nogastopilot.
a. LP-regulator shut down due to inlet pressure too high
- Verify LP tank regulator is installed and set at 11" to
