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. NOTE: Full-vat units have a two-piece insulation retainer and two pieces of 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, high-limit thermostats, and other pipe fittings using Loctite® PST56765 sealant or
equivalent on the threads.
