replace ignitor.

 

Broken spark electrode

• Check for broken ceramic insulation, replace

 

 

electrode if broken.

 

 

 

 

Misaligned spark electrode

Problem with

• Check for proper connection of the thermocouple

to the rear of the valve. If loose, fully tighten.

 

 

• Check pilot for full flame impingement around

 

 

thermocouple. If flame is too small, check gas

 

 

pressure, adjust pilot rate screw, check pilot

 

 

head for damage.

 

 

• Check thermocouple voltage at valve. It

 

 

must be greater than 5 mV. If low, replace

 

 

thermocouple.
