If the gas quality is bad, your pilot may not stay lit, the burners may produce soot and the heater may backfire when lit. If the gas quality or pressure is
low, contact your local gas supplier immediately.
1. When ignitor button is pressed, there is no spark at ODS/
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
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,

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 flame, 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

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 flame not touching thermocouple, which allows
thermocouple to cool, causing pilot flame to go out. This
problem could be caused by either low gas pressure or
dirty or partially clogged ODS/pilot - Contact local gas

c. Inlet gas pressure is too low - Contact qualified service
person.
9. If burning at main burner orifice occurs (a loud, roaring blow
torch noise).
a. You must turn off burner assembly and contact a qualified
