SECTION E – ADJUSTMENTS "FOR QUALIFIED SERVICE PERSONNEL ONLY"
NOTE: Only for qualified service personnel specializing in Hotel and Restaurant Cooking Equipment. Factory approval required prior to any
warranty repairs.
E1 – Safety Pilot: Remove Pilot Adjustment Cap (B) and turn Adjustment Screw to provide properly sized flame (¾ inch long). Replace Cap
and leak test with Soap Solution. Tighten cap is necessary.
E2 – Burners: Burners are factory set for maximum performance. Should further adjustment be required, loosen the Slotten Hex Screw on
side of Venturi and rotate air shutter until flame with soft blue inner cone is achieved. Remove any lint accumulated, if necessary.
E3 – Thermostat Calibration: Turn the Thermostat Knob to 375°F and remove knob without moving thermostat shaft. Place narrow bladed
screw driver (⅛ inch) into hollow thermostat shaft and engage center adjustment screw. When thermometer reading approached 375°F,
slowly turn the adjustment screw clockwise until burners go out. Turning the screw counter-clockwise will increase the temperature.
NOTE: One quarter turn will change temperature setting approximately 25°F. Replace knob and check temperature through 3 cycles. Repeat
adjustments if necessary until knob setting is correct within a few degrees.

E4 – Troubleshooting Guide
Problems
A. Pilot will ignite but will not remain
alight when Gas Cock Dial is released.
B. Main Burners will not fire with supply
gas valve open and incoming gas
present.
C. Main Burners and Safety Pilot go out
after fryer has reached operating
temperature.
D. Main Burners do not come up to full
power, flames appear to be lazy. Takes
too long to reach operating temperatures.
E. Frying temperature too high –
shortening scorches and discolors
quickly.
Cause
1) Loose electrical connection at Hi-Limit
Switch, Gas Control Valve or Thermostat.
2) Pilot flame too low.
3) Dirt in pilot.
4) Excessive draft caused by exhaust, air
conditioner or make-up air equipment.
5) Thermopile defective.
1) Loose connections at Thermostat
Switch or Gas Control Valve.
2) Defective Thermostat Switch, Gas
Control Valve or GS-7 Hemostat.
1) Hi-Limit Safety Switch cut out due to
out of calibration Thermostat.
1) Gas pressure drop.
2) Defective or incorrect Gas Control
Valve.
1) Thermostat set too high.
2) Shortening contaminated or of low
quality.
Remedies
1) Retighten connections (see
illustrations 2 and 2a).
2) Relight and adjust (as per instructions
in Section E).
3) Remove pilot burner orifice, blow out
dirt, replace, and relight pilot burner.
4) Reduce draft by regulating or diverting
air flow.
5) Replace Thermopile.
1) Retighten connections (see
illustrations 2 and 2a).
2) Replace in that order.
1) Recalibrate Thermostat as per
instructions in Section E3. If temperature
is OK replace Hi-Limit Switch and light
pilot.
1) Check gas manifold pressure by
removing ⅛" NPT Plug and measuring
pressure using U-Gauge Manometer.
With Burners on, pressure should read
3.5'' WC for NAT and 10.0'' WC for
PROP gas. Check Supply Line sizing.
See Section A, "Gas Connection."
2) Replace Gas Control Valve (see
Illustration 2 and 2a).
1) Check temperature of shortening and
adjust thermostat (as per instructions in
Section E).
2) Filter or strain shortening. Use higher
grade shortening.
