PST56765 or equivalent pipe thread sealant.
6. Reconnect the gas valve assembly to the fryer using Loctite
®
PST56765 or equivalent pipe thread
sealant, and reattach the flexible gas line(s), enrichment tube(s), and the vent tube (on non-CE
units). Reconnect the high-limit thermostat wires and drain safety wires to the valve.
7. Reconnect the fryer to the gas supply and open the cut off valve. Apply a solution of soapy water
around each connection to check for gas leaks. Eliminate any that are found.
8. Reconnect the fryer to the electrical power supply and check for proper operation.
1.9.9 Replacing a Burner Assembly
1. Disconnect the unit from the electrical and gas supplies.
2. Remove the combustion air blower per the procedure found in Section 1.6.6.
3. Remove the four nuts from the air plenum assembly and pull the assembly straight out toward you
until it clears the burner tubes.
NOTE: On a dual-vat fryer, it may be necessary to remove the drain valve handles before the
plenum can be removed.
NOTE: If the flexible oil return lines are blocking the plenum, carefully bend them upward
enough to clear the plenum.
4. Disconnect the ignition cable from the ignitor by grasping its boot and pulling gently toward you.
Disconnect the flame sensor wire from the ignitor by gently pulling its push-on terminal from the
terminal strip on the ignitor.
5. Disconnect the flexible gas lines from the burner orifice and the enrichment tube from the ignitor
assembly.
6. Remove the four ¼-inch nuts securing the outer front covers to the frypot assembly.
7. Remove the sheet metal screws at the top of the outer front covers and pull the covers straight out
toward you until clear of the mounting studs.
8. Remove the washers and tubular spacers from the mounting studs, then pull the inner covers
straight out toward you until clear of the mounting studs.
9. Grasp the burner firmly and pull it toward you until it clears the burner channels, taking care not
to damage the ceramic tiles in the process.
10. Clean all debris from the burner channels and combustion area.
11. 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 1.6.11 for procedure.
b. If the welds in the upper rail are cracked or burned out, the upper rail must be replaced. Refer
to Section 1.6.12 for procedure.
12. Place a new insulating strip along the top, rear, and bottom edge of the burner and carefully slide
it straight into the rails. NOTE: Use P/N 826-0931 for full-vat frypots and P/N 826-0932 for
dual-vat frypots.
13. Reverse steps 1 through 9 to reassemble the components.
14. 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.
15. Visually examine the burner flame. The color and intensity on both sides should be the same.
16. Use an inspection mirror to check for leaks in areas that cannot be directly observed.
17. If a leak is detected, tighten all the lower insulation retainer nuts, allow the frypot to run for five
additional minutes, and repeat steps 15 and 16.
