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 pipefittings using Loctite
PST56765 sealant or equivalent on the threads.
