Troubleshooting the Millivolt Gas Control System 

 

Problem 

Possible Causes 

Corrective Action 

Defective or misaligned 
electrode at pilot. 

Check for spark at electrode and pilot: if no spark 
and electrode wire is properly connected, replace 
igniter. 

Spark igniter will not 
light. 

Defective igniter (push-
button). 

Using a match, light pilot. If pilot lights, turn off pilot 
and push the red button again. If pilot will not light - 
check gap at electrode and pilot should be 1/8" to 
1/4" to have a strong spark. 

Defective thermocouple 
(flame switch where 
applicable). 

Check pilot flame. Must impinge on generator and 
thermocouple. Clean and/or adjust pilot for 
maximum flame impingement on generator and 
thermocouple. Replace thermocouple if pilot will not 
hold. (Hand tight 1/8 turn on replacement) 

Pilot will not stay lit 
after carefully following 
lighting instructions. 

Defective valve magnet. 

Replace valve, if pilot won't hold after the 
thermocouple is replaced. 

Wall switch or wires 
defective. 

Check wall switch and wires for proper connections. 
Jumper wire across terminals at wall switch. If 
burner comes on, replace defective wall switch. If 
okay, jumper wires, across wall switch wires at 
valve. If burner comes on, wires are faulty or 
connections are bad. 

Generator may not be 
generating sufficient 
voltage. 

Check generator with millivolt meter. Take reading at 
generator terminals of gas valve. Should read 325 
millivolts minimum while holding valve knob 
depressed in pilot position and wall switch "off" 
Replace faulty generator if reading is below 
specified minimum. 

Plugged burner orifice. 

Check burner orifice for stoppage and remove. 

Pilot burning, no gas to 
burner, valve knob 
“ON”, and wall switch 
“ON”. 

Defective automatic valve 
operator. 

Remove wall switch wires from gas valve. Install 
jumper wires from top bottom terminals of gas valve. 
Turn valve on "ON". If main burner does not light, 
replace valve. 

Frequent pilot outage 
problem. 

Pilot flame may be too low 
or blowing (high) causing 
the pilot safety to drop out. 

Clean and/or adjust pilot flame for maximum flame 
impingement on generator and thermocouple. 

Flame lifts off burner 
and goes out in less 
than 30 seconds. 

Inner 4” liner has come off 
flue or termination, flame 
is starving for oxygen. 

Attach 4" liner to flue or termination using screws, 
silicone and clamps as stated in manual. 

Flame lifts off burner 
on one side while the 
rest of the flame 
remains lit. 

Improper installation of 
firebrick. Firebrick is likely 
leaning. 

Be sure to position firebrick against firebox walls and 
be sure to use brick clips attached to the inner side 
of firebox. 

 

Burner System Maintenance 

It is recommended to annually inspect and clean the Burner System to prevent malfunction and / or sooting. This operation 
should be performed by your dealer or a qualified technician. 

 

 

-CAUTION- 

Before servicing the burner system ensure that the gas supply is turned OFF and disconnect all electrical 
connections to the appliance. Allow the appliance to cool to room temperature. Note that the pilot assembly 
may be hot in an intermittent or standing-pilot system—even if the main burner was never on. Exercise 
caution when working within the area. 

-ALL WORK SHOULD BE PERFORMED BY A QUALIFIED AND CERTIFIED TECHNICIAN- 

 

WARNING: BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE THE GLASS FRONT. 

NOTE: Before troubleshooting the gas control system, be sure external gas shut off is in the "On" position.
