1.8 Troubleshooting and Problem Isolation

24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES

13.Install new firebox into cabinet. Replace screws (12) removed during removal of the old firebox. Use spray adhesive (Zep Aero Tac High-Strength Spray Adhesive or equivalent) to install new insulation in firebox bottom as shown. The insulation must not go above the top of the burner- box center flange.

NOTE: Ensure the strip of insulation is properly affixed to the front blower- housing flange (arrow) prior to installing frypot. Failure to install the insulation strip will result in frypot-baffle burnout, blower damage and fryer malfunction, and will void all applicable warranties.

14.Install new frypot, using care not to damage the firebox insulation. Ensure the blower-housing insulation strip remains in place after installing the new frypot (arrow).

Reverse the above steps to reassemble the fryer. Use high-temp silicone to re-install the top assembly (single fryers) or joiner strips, flue caps, etc. (systems).

Install new insulation in firebox using spray adhesive, ensuring good contact between insulation and metal surfaces.

Ensure blower-housing insulation strip remains in place after installing the new frypot (arrow).
