TROUBLESHOOTING

SYMPTOMS - POSSIBLE CAUSES AND CORRECTIONS

IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover, cigarette smoke, cements and glues, new carpet or textiles, etc., create fumes. These fumes may mix with combustion air and create odors.

1.When ignitor button is pressed, there is no spark at ODS/ pilot.

a.Ignitor electrode positioned wrong - Replace ignitor.

b.Ignitor electrode broken - Replace ignitor.

c.Ignitor electrode not connected to ignitor cable - Reconnect ignitor cable.

d.Ignitor cable pinched or wet - Free ignitor cable if pinched by any metal or tubing. Keep ignitor cable dry.

e.Broken ignitor cable - Replace ignitor cable.

f.Bad piezo ignitor - Replace piezo ignitor.

2.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 gas 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 down control knob. Repeat igniting operation until air is removed.

e.Depleted gas supply - Contact local gas company.

f.ODS/pilot is clogged - Clean ODS/pilot or replace ODS/ pilot assembly.

g.Gas regulator setting is not correct - Replace gas regulator.

3.ODS/pilot lights but flame goes out when control knob is released.

a.Control knob not fully pressed in - Press in control knob fully.

b.Control knob not pressed in long enough - After ODS/pilot lights, keep control knob pressed in 30 seconds.

c.Safety interlock system has been triggered (thermostat models only) - Wait one minute for safety interlock system to reset. Repeat ignition operation.

d.Manual Shutoff valve not fully open - Fully open manual shutoff valve.

e.Thermocouple connection loose at control valve - Hand tighten until snug, then tighten 1/4 turn more.

f.Pilot flame not touching thermocouple, which allows thermocouple to cool, causing pilot flame to go out. This problem could be caused by either 1) low gas pressure - Contact local gas company or 2) dirty or partially clogged ODS/pilot - Clean ODS/pilot or replace ODS/pilot assembly.

g.Thermocouple damaged - Replace thermocouple.

h.Control valve damaged - Replace control valve.

4.Main burner does not light after ODS/pilot is lit.

a.Main burner orifice clogged - Clean main burner or replace main burner orifice.

b.Main burner orifice diameter is too small - Replace main burner orifice.

c.Inlet gas pressure is too low - Contact local gas company.

5.Pilot burning, no gas to burner, valve knob "ON", on/off switch "ON."

a."On/Off" switch, wall switch, remote control or wires defective - Check "on/off" switch and wires for proper connections. Place jumper wires across terminal at switch

-if burner comes on, replace defective switch. If OK, place jumper wires across switch wires at gas valve-if burner comes on, wires are faulty or connections are bad.

b.Thermopile may not be generating sufficient millivolts

-If the pilot flame is not close enough physically to the thermopile, clean the ODS/pilot.

-Be sure the wire connections from the thermopile at the gas valve terminals are tight and the thermopile is fully inserted into the pilot bracket.

-Check the thermopile with a millivolt meter. Take the reading at TH-TP & TP terminals of the gas valve. The meter should read 350 millivolts minimum, while holding the valve knob depressed in the PILOT position, with the pilot lit, and the ON/OFF switch in the OFF position. Replace the faulty thermopile if the reading is below the specified minimum.

-With the pilot in the ON position, disconnect the thermopile leads from the valve. Take a reading at the thermopile leads. The reading should be 350 millivolts minimum. Replace the thermopile if the reading is below the minimum.

c.Defective valve - Turn valve knob to "ON." Place ON/OFF switch to "ON." Check with millivolt meter at thermopile terminals. Millivolt meter should read greater than 200 millivolts. If the reading is okay and the main burner does not ignite, replace the gas valve

d.Plugged main burner orifice - Check main burner orifice for blockage and remove.

6.Delayed ignition of main burner.

a.Manifold pressure is too low - Contact local gas company.

b.Main burner orifice clogged - Clean main burner and main burner orifice.

7.If burning at main burner orifice occurs (a loud, roaring blow torch noise).

a.You must turn off burner assembly and contact a qualified service person.

b.Main burner orifice is clogged or damaged – Clean main burner and main burner orifice or replace main burner orifice.

c.Damaged main burner – Replace damaged main burner.

d.Gas regulator defective – Replace gas regulator.

8.Yellow flame in front section of main burner during main burner combustion.

a.Not enough air - Check main burner for dirt and debris. If found, clean main burner.

b.Gas regulator defective - replace gas regulator.
