16. Place the upper inner combustion chamber insulation and insulation retainers (3) on the top two studs on
each side of the front of the frypot and secure with ¼"-20 washer-nuts. It is normal for the retainers to slice
off the overhanging insulation.
17. Place the lower rear combustion chamber insulation (4) on the lower four studs at the rear of the frypot.
18. Place one 1.625-inch tubular spacer (5) on each of the flue assembly (upper) studs at the rear of the frypot.
NOTE: There are three different sizes of spacers. Verify the size to ensure the correct spacers are installed.
19. Press the flue assembly (6) over the burner rails. It may be necessary to use a rubber mallet or screwdriver
to align the components. Use four ¼"-20 washer nuts to secure the flue assembly. Do not tighten the
retainer nuts at this point. They should be finger-tight only. NOTE: The flue edge will cover one to
two inches of the lower insulation.
20. Install the lower rear combustion chamber back(s) and retainer(s) (7) with the flanged edge(s) against the
flue. Secure with ¼"-20 washer nuts. NOTE: Full-vat units have two-piece backs and four retainers.
Dual-vat units come with one-piece backs and only two retainers.
21. Insert the burners (9) into the rails to ensure the rail spacing and alignments are correct. The burner should
slide freely into and out of the rails. The upper rail can be bent slightly to increase or decrease tension on
the burner and the edges of the slot can be closed or opened slightly to best fit the burner frame.
22. Carefully wrap a strip of burner insulation (8) tightly around the rear and sides of the burner frame (9), with
the glass-tape side of the strip on the outside. Do not use duct tape or adhesive to secure the strip to the
burner frame.
23. Align the burner to the burner rails while maintaining tension on the insulation strip. Insert the burner at a
slight angle and begin pushing the burner slowly into the rails until it contacts the rear combustion chamber.
The fit should be snug, but not excessively tight.
24. Verify that the burners are flush with the front edge of the burner rails. Remove the excess burner
insulation by cutting with a knife or diagonal pliers. Do not try to tear the insulation!
25. Insert the upper front insulation (10) into its retainer (11), making sure that the holes in each piece are
aligned with one another. Install the assembly with the insulation side toward the frypot and secure with
¼"-20 washer-nuts. Do not over tighten.
26. Place a washer on each of the four lower studs on the front of the frypot. Install the lower inner front
insulation (12) with the rectangular openings toward the drain valve nipple. Install the lower inner front
insulation retainer(s) (13). NOTE: Full-vat units have a two-piece insulation retainer. Dual-vat units have
a one-piece retainer.
27. If necessary, replace the sight-glasses and insulation (14).
28. Place one washer and one 1.888-inch spacer (15) on each stud. NOTE: There are three different sizes of
spacers. Verify the size to ensure the correct spacers are installed.
29. Insert the front lower insulation (16) into the front lower insulation retainer(s) (17) and install assembly on
frypot. Secure with ¼"-20 washer-nuts. If frypot uses two retainers, connect them together with two ¼"
self-tapping screws.
insulation. Dual-vat units have one-piece components.
30. Return to the rear of the frypot and fully tighten all washer-nuts.
31. Remove and replace the plenum gaskets (18).
32. Place a 0.938-inch spacer (19) on the plenum-mounting studs, and mount the plenum (20). Ensure the
gaskets are clear of the burner tubes by pulling the plenum back slightly. Place a washer on each stud and
secure plenum with ¼"-20 lock-nuts.
33. Install the upper oil-zone insulation (21) by pressing it under the upper combustion chamber metalwork.
Secure the insulation with the bracket (22) and ¼" self-tapping screws.
34. Install the upper burner rail blanket insulation (23). Position any excess insulation toward the top of the
frypot. Avoid overhang past the bottom of the upper burner rail. Overhang in this area will make future
burner replacement more difficult.
35. Cover the insulation with the insulation retainer (24), and secure with ¼" self-tapping screws.
36. Reinstall probes, drain valves, AIF boards, actuators, high-limit thermostats, and other pipe fittings using
Loctite® PST56765 sealant or equivalent on the threads.
NOTE: Full-vat units have a two-piece insulation retainer and two pieces of
