Liquid shortening does
not reach the desired
temperature for frying.

1. Low gas supply pressure [less than 6”W.C.

for natural gas (11” W.C. for propane)
when all other gas-powered equipment is
operating], causing reduced heat from main
burners.

2. Low gas manifold pressure [less than 3½”

W.C.for natural gas (10” W.C. for pro-
pane).

3. Loose knob on thermostat; or thermostat

requires calibration (temperature setting
differs by about 10°F from the measured
shortening temperature).

Main burners do not
stop burning.

1. Thermostat has failed.

2. Gas control valve has failed.

1. Turn the thermostat control

knob to OFF. If the burners
do not quit burning, the ther-
mostat has failed and must
be replaced.

2. Turn the gas control valve knob

to OFF. If the burners do not
quit burning, the gas control
valve has failed and must be
replaced.

1. Measure the gas supply pres-

sure.
Contact your local gas supplier
to obtain adequate gas supply
volume and pressure.

2. Measure the gas pressure at

the fryer’s manifold pressure
tap. Adjust the manifold pres-
sure (see Figure 6), as neces-
sary: [a] Unscrew (and re-
tain) the threaded Main Burner
Regulator Adjustment Cover.
[b] Use a flat-blade screw-
driver to turn the regulator
adjustment screw (clockwise to
increase; counterclockwise to
decrease) to reset the pressure
adjustment. [c] Reinstall, and
tighten the Regulator Adjust-
ment Cover, when finished.

3. Stir the shortening to mix the

hot shortening with some from
the lower ‘cool zone’ and allow
it to sit for 5 minutes. Turn the
thermostat knob until it ‘clicks’
on (causing the main burners to
flame); note the setting where
this occurs. Turn the thermo-
stat knob until it ‘clicks’ off
(causing the main burners to go
out); note the setting where this
occurs. Repeat this tempera-
