Short Cycle: The thermostat will cycle rapidly whilethe fryer is in the idle mode; the temperature will beerratic.Thermostat Bulb Positioning 18 " & up Fryer GasSERVICEALL HI-LIMIT CONTROLS ARE PRESET AT THEFACTORY FOR A SPECIFIC TEMPERATURE. DONOT ATTEMPT TO CHANGE THE SETTING OF THEHI-LIMIT. IF THE HI-LIMIT FAILS TO SHUT OFFBETWEEN 425°F AND 450°F DURING TESTING, ITMUST BE REPLACED.FLAME ADJUSTMENTA. Gas Pressure1. At gas valve, remove adjustment port cover, rotateadjustment screw with screwdriver and replaceport cover.2. To check the gas pressure (3" WC for natural gasor 10" WC for Propane at the manifold), use anallen wrench to remove the gas pressure test port,located in the center of the manifold.3. Line pressure (incoming pressure) is critical forproper ignition of the IFM. Incoming pressure mustbe : Natural - 7” W.C.Propane - 11” W.C.B. Air Flow1. To determine the proper gas/air mixture, look intothe viewing window for each burner, located just tothe left of each burner air hose where the hose isconnected to the burner assembly. (See figurebelow).• bright red/orange with proper mixture – orange“glow” around burner tube• too much gas – orange “haze” around burnertube (showing incomplete combustion)• too little gas – blue at front of burner, or totallyblueREQUIRED TEST THERMOSTATMultimeter (for testing continuity)CHECKING CONTINUITY WITH THE MULTIMETER1. Rotate the thermostat shaft until an audible click isheard.2. Rotate the thermostat shaft left and right ten timescausing the switch to click on and off ten times,while using the Multimeter to verify continuity.3. If the switch does not show continuity during allten trials, replace the thermostat.Disassembling the thermostat will void thethermostat warranty.1.

Apply oil resistant flexible sealant ontocompressionfitting thread before installing fitting into fryervessel.4. Position bent portion of bulb against far right heattransfer tube and install compression fitting snuglyinto fryer vessel.5. Adjust bulb so at least 2” of bent portion of it is nextto heat transfer tube and tighten compression nutonto compression fitting for fryer 18 & up. The endof thermostat bulb should touch the burner tube for14" fryers.6. Refill fryer with oil to “fill level line”.7. Start fryer, preheat and calibrate withthermometer.SERVICE DIAGNOSISA properly adjusted Keating Incredible FryingMachine® (IFM), with no load, will cycle “On”approximately every 2 1/2 to 3 minutes. Each cycle willlast 15 to 25 seconds, ensuring that the temperaturesetting is held within a narrow band.• Every Keating Incredible Frying Machine®(IFM) has a number of safety controls toensure safe operation and guard againstcomponent failure.10Remove the cover by loosening the screws to gain access to theburner viewing windows (14” Model Shown).
