as a bending template for the new pilot assembly. Note
the placement/order of the wires in the manifold component
block.

Lift the pilot/thermopile assembly (including the igniter wire)
from the manifold assembly.
NOTE: Read this step carefully before proceeding. Use the
old pilot/pilot tube assembly as a guide, bend the new pilot
tube to match the old one. Make only the bends closest to
the pilot before going to the next step.
7. Route the new pilot tube, new igniter wire and new
thermopile wire through the opening in the manifold door
(Figure 38).

8. Using the pilot/thermopile assembly screw removed earlier
reattach the new pilot/thermopile assembly. Reattach the
burner to the manifold using the screws removed earlier.
NOTE: make sure the burner scoop is oriented to the pilot
side of the manifold tube (Figure 35).
9. Reinstall the manifold component block in the manifold door
(Figure 38).
10. Carefully bend the new pilot tube to match the bend of the
manifold tube. NOTE: When bending DO NOT crimp or
crease the pilot tube.
11. Before you proceed to the next step, install the new brass
ferrule nut in the gas control valve/thermostat’s pilot tube
opening. HAND TIGHT ONLY.
12. Follow the “Replacing the Burner/Manifold Assembly”
instructions to replace the manifold door.
Cleaning the Combustion Chamber and
Flame-arrestor_________________________
1. Follow procedure outlined in “Removing the Manifold/
Burner Assembly.”
2. Use a vacuum cleaner/shop vac to remove all loose debris
in the combustion chamber (Figure 39). Use compressed
air to clear any dust or debris that may have accumulated
in the flame-arrestor.
COMBUSTION CHAMBER
Reassemble by following the procedure under “Replacing
the Manifold/Burner Assembly.”
