 try to light the burner by hand. 

 

Lighting Instructions 

1.  Set the thermostat to the lowest temperature. 
2.  The control knob on the gas valve should be in the “OFF” position for at least five minutes. 
3.  Rotate the control knob counter-clockwise to the “ON” position and set the thermostat to the desired 

temperature settings.  The burner will energize on call for heat.

1.  Turn the thermostat off or

 

turn the main power off. 

2.  Wait five minutes. 
3.  Return thermostat to the desired setting or turn the main power on.

Two electrodes act as a sparker and a flame rod. Flame rectification by this flame rod monitors the continued 
presence of the burner flame.
