• Verify that the flue opening is not obstructed by debris or accumulations of solidified oil or
shortening.
• Verify that burners and associated components (i.e. gas valves, pilot assemblies, ignitors, etc.)
are in good condition and functioning properly. Inspect all gas connections for leaks and verify
that all connections are properly tightened.
• Verify that the burner manifold pressure is in accordance with that specified on the appliance’s
rating plate.
• Verify that the temperature and high-limit probes are properly connected, tightened and
functioning properly, and that probe guards are present and properly installed.
• Verify that component box components (i.e. computer/controller, transformers, relays, interface
boards, etc.) are in good condition and free from oil migration build-up and other debris. Inspect
the component box wiring and verify that connections are tight and that wiring is in good
condition.
• Verify that all safety features (i.e. drain safety switches, reset switches, etc.) are present and
functioning properly.
• Verify that the frypot/cookpot is in good condition and free of leaks and that the frypot/cookpot
insulation is in serviceable condition.
• Verify that wiring harnesses and connections are tight and in good condition.
Built-In Filtration System
• Inspect all oil-return and drain lines for leaks and verify that all connections are tight.
• Inspect the filter pan for leaks and cleanliness. If there is a large accumulation of crumbs in the
crumb basket, advise the owner/operator that the crumb basket should be emptied into a fireproof
container and cleaned daily.
• Verify that all O-rings and seals (including those on the Power Shower and on quick-disconnect
fittings) are present and in good condition. Replace o-rings and seals if worn or damaged.
• Check filtration system integrity as follows:
− With the filter pan empty, place each oil return handle, one at a time, in the ON position.
Verify that the pump activates and that bubbles appear in the cooking oil/shortening (or that
gurgling is heard from the Power Shower port) of the associated frypot..
− Close all oil return valves (i.e., place all oil return handles in the OFF position). Verify
proper functioning of each oil return valve by activating the filter pump using the lever on
one of the oil return handle microswitches. No air bubbles should be visible in any frypot (or
no gurgling should be heard from the Power Shower ports).
