Inspect pilot burner assembly and the ignition electrode and replace ionization rod (flame
rod). Replace the gaskets for the pilot burner assembly and ionization rod (flame rod).
Note the gap between the ignition electrode and the pilot burner flame rod. The
acceptable gap range is between 3 mm and 5 mm. Adjust the ignitor electrode as
necessary. Note the geometry of the
ionization rod (flame rod) if the spacing
between the rods (after replacement)
and the burner does not match factory
recommendations please consult
Patterson-Kelley for correct actions.
Refer to the following images for proper
factory spacing – dimensions are in
millimeters
NOTE: The pilot burner assembly
must be installed in the correct
direction, the pilot burner should be
on the bottom and the ignition
electrode on the top when installing
the pilot burner assembly into the
burner door. IT WILL NOT
FUNCTION CORRECTLY IF
INSTALLED UPSIDE DOWN.
3. Check burner for signs of deterioration or corrosion. Replace burner immediately if any
deterioration, corrosion, or damage is found. If damage to the burner is suspect from improper
combustion settings, be sure to do a combustion check to the factory preferred settings.
The burner may be cleaned with water if any accumulated dust or lint is found. This must be
done with the burner outside of the combustion chamber.
