NOT
ATTEMPT TO CHANGE THE SETTING OF THE
HI-LIMIT. IF THE HI-LIMIT FAILS TO SHUT OFF
BETWEEN 425°F AND 450°F DURING TESTING, IT
MUST BE REPLACED.
FLAME ADJUSTMENT
A. Gas Pressure
1. At gas valve, remove adjustment port cover, rotate
adjustment screw with screwdriver and replace
port cover.
2. To check the gas pressure (3" WC for natural gas
or 10" WC for Propane at the manifold), use an
allen wrench to remove the gas pressure test port,
located in the center of the manifold.
3. Line pressure (incoming pressure) is critical for
proper ignition of the IFM. Incoming pressure must
be : Natural - 7” W.C.
Propane - 11” W.C.
B. Air Flow
1. To determine the proper gas/air mixture, look into
the viewing window for each burner, located just to
the left of each burner air hose where the hose is
connected to the burner assembly. (See figure
below).
• bright red/orange with proper mixture – orange
“glow” around burner tube
• too much gas – orange “haze” around burner
tube (showing incomplete combustion)
• too little gas – blue at front of burner, or totally
blue
REQUIRED TEST THERMOSTAT
Multimeter (for testing continuity)
CHECKING CONTINUITY WITH THE MULTIMETER
1. Rotate the thermostat shaft until an audible click is
heard.
2. Rotate the thermostat shaft left and right ten times
causing 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 all
ten trials, replace the thermostat.
Disassembling the thermostat will void the
thermostat warranty.
1. Set compression ring onto capillary end of bulb
finger tight, 1/2” from end of capillary.
2. Insert new thermostat bulb through control panel
back.
3. Apply oil resistant flexible sealant ontocompression
fitting thread before installing fitting into fryer
vessel.
4. Position bent portion of bulb against far right heat
transfer tube and install compression fitting snugly
into fryer vessel.
5. Adjust bulb so at least 2” of bent portion of it is next
to heat transfer tube and tighten compression nut
onto compression fitting for fryer 18 & up. The end
of thermostat bulb should touch the burner tube for
14" fryers.
6. Refill fryer with oil to “fill level line”.
7. Start fryer, preheat and calibrate with
thermometer.
SERVICE DIAGNOSIS
A properly adjusted Keating Incredible Frying
Machine® (IFM), with no load, will cycle “On”
approximately every 2 1/2 to 3 minutes. Each cycle will
last 15 to 25 seconds, ensuring that the temperature
setting is held within a narrow band.
• Every Keating Incredible Frying Machine®
(IFM) has a number of safety controls to
ensure safe operation and guard against
component failure.
