1.9.9 Replacing a Burner Assembly
1. Disconnect the unit from the electrical and gas supplies.
2. Remove the gas line and enrichment tube using a 7/16” and 5/8” wrench from the front of the burner.
3. Remove the elbow and tee off the bottom of the burner to ensure easier
removal of the burner.
4. Remove the fryer back.
5. Remove the screws attaching the flue cap to the brace.
6. Remove the top cross brace in the back.
7. Remove the flue by removing the two screws in the rear and one screw in
the front of the flue.
8. Remove all the screws on the flue collector and bend back the tabs and remove the
collector.
9. Remove four screws on the collector insulation plate (see Figure 1).
10. Remove the four nuts and cover of the lower insulation retaining cover (see Figure
2).
11. Carefully remove the insulation.
12. Grasp the burner firmly and slide the burner out the rear of the fryer. Pull it toward
you until it clears the burner channels, taking care not to damage the ceramic tiles in
the process.
13. Slide the burner out the rear of the fryer.
14. Clean all debris from the burner channels and combustion area.
15. Inspect the upper and lower burner rails for cracked or burned out welds.
a.
If the welds in the lower rail are cracked or burned out, the frypot must be
replaced. Refer to Section 1.9.11 for procedure.
b. If the welds in the upper rail are cracked or burned out, the upper rail must be
replaced. Refer to Section 1.9.12 for procedure.
16. Wrap a new insulating strip along the top, rear, and bottom edge of the burner.
NOTE:
Use P/N 826-0931 for full-vat frypots and P/N 826-0932 for dual-vat
frypots.
17. Carefully slide the replacement burner into the rails starting at the top and lifting
slightly up on the bottom (see Figure 3). Ensure that the insulation is not torn or
damaged.
18. In reverse order, reassemble insulation and holding plates.
19. Install flue collector.
20. Install the flue.
21. Install the cross brace, ensuring the flue cap is secured to the brace.
22. Replace the fryer back.
23. Reattach the elbow, gas line and enrichment tubes to the front of the burner.
24. Fill the frypot with oil. Turn the fryer on; turn off or bypass the melt cycle and operate the unit for at least 10
minutes.
25. Examine the burner flame. The color and intensity on both sides should be the same.
26. Use an inspection mirror to check for leaks in areas that cannot be directly observed.
27. If a leak is detected, tighten all the lower insulation retainer nuts, allow the frypot to heat for five additional
minutes, and repeat steps 25 and 26.
28. If a leak persists, use a rubber hammer and a small block of wood to tap the corners of the lower combustion
chamber insulation retainers. Repeat steps 25 through 27.
Repeat this step until no leakage is detected.
