QUALIFIED TECHNICIANS ONLY
1 Cabinet inspection
Inspect the cabinet, inside and out, front and rear, for
excessive oil buildup.
2 Check regulated gas pressure.
Contact the local gas company or a service agency to
check the gas pressure out of the fryer’s gas regulator.
For natural gas, the pressure must be 3.0 in. W.C.
(76 mm W.C.) For propane gas, the pressure must be
8.25 in. W.C. (210 mm W.C.)
If the pressure does not meet these standards, ask the
service agency or gas company to adjust the pressure to
meet the standard.
3 Probe check
Verify that the temperature and high-limit probes are
properly connected, tightened and functioning properly,
and that mounting hardware and probe guards are
present and properly installed.
4 Clean and Replace gas valve vent tube.
Clean and replace the gas valve vent tube. Follow the
cleaning procedure in the service manual.
5 Clean combustion air blower.
Clean the combustion air blowers. Follow the cleaning
procedure in the service manual.
6 Check fryer recovery time.
Choose a vat on the fryer. Check the fryer’s most re-
cent recovery time for that vat, using the procedure in
FR3 M1. The most recent recovery time should be less
than 2:25 (two minutes, twenty-five seconds).
If the fryer’s recovery time is less than 2:25 (two min-
utes, twenty-five seconds).the procedure is complete
for this vat. Go to step 7.
7 Check combustion.
If the fryer’s recovery time is less than 2:25 (two min-
utes, twenty-five seconds).skip this step.
Connect the multimeter in series with the white flame
sensor wire on the igniter. Allow the burner to operate
for at least one minute after the melt cycle is com-
pleted. After 1 minute, the reading on the multimeter
should between 2.5 and 3.5 microamps. Any other
reading is not acceptable.
After 90 seconds of continuous operation, check the
color of the burner. The burner should glow bright or-
ange-red. Use the Burner Color Comparison Chart
inside the door of the fryer to identify the correct color.
A blue flame or dark spots on the burner face are not
acceptable.
