Pilot Inspection, Testing and Replacement (cont’d) 
Step 7. 

Disconnect the spark igniter/flame sensor wire from 

gas control. 

Step 8. 

Remove the burner assembly from the combustion 

chamber.

Step 9. 

Remove the pilot assembly from the main feedline 

using a 1/4" nut driver. 

Step 10. 

Visually inspect the spark igniter/flame sense wire for damage. Replace 

the pilot assembly, if damage is found. 

Step 11. 

With a multi-meter set to the ohms setting, check 

continuity through the spark igniter/flame sense wire.  Replace 
the pilot, if there is no continuity. 

Step 12. 

Visually inspect the spark igniter/flame sense electrode for deterioration. 

Replace the pilot assembly, if necessary.  The electrode should not be in contact with 
pilot hood.  If it is in contact with the pilot hood, carefully adjust electrode to a gap 
distance of  3/32" from the pilot hood. 
Step 13. 

Visually inspect the spark igniter/flame sense electrode for oxidation build 

up.  Carefully clean any oxidation using very fine emery cloth.
