Chapter 4: Service

This chapter provides the qualified technician with the replacement and troubleshooting procedures
necessary to service the Pitco fryer.

4.1 REPLACEMENT PROCEDURES
These procedures are provided to the qualified technician as a guide to removal and replacement of

various fryer components. If a test is required to verify component operation after installation, it
will be referenced.

WARNING

To prevent bums, always ensure the fryer is completely SHUT DOWN and
COOLED down before working on the fryer. Do not break any fryer gas
connections while the unit is connected to a gas supply line.

WARNING

The power supply must be disconnected before servicing or cleaning the
appliance.

4.1.1 Main Burner Removal and Replacement

a. Loosen the set screw in the base of the burner casing.
b. Unscrew and remove the two hex head screws at the top of the burner.

c. Loosen the set screw on the air collar. Lift the burner and air collar up to clear the top of

the burner fitting. Remove the burner from the fryer.

d. To re-install the burner, reverse the procedure.

4.1.2 Changing the Main Burner Orifice

a. Unscrew the orifice with a 3/8" wrench and remove the orifice.
b. Insert the new orifice and tighten with the 3/8" wrench. Ensure the orifice is tight

enough to prevent gas leakage around the orifice.

4.1.3 Replacing the Heat Baffles

a. Remove the Main Burner as described in 4.1.1.

4-1

b. The heat baffles are located inside the heat tubes. They are attached to the rear of the

baffle supported by tack welds. Using a chisel, break away the baffle support and
remove the old baffles. Be careful not to puncture the heat tubes because this will require
complete tank replacement.

c. Insert the new baffles in the tubes in the original position. The new baffles sit in position

and do not require welding.

d. Install the main burners.

4.1.4 Pilot Burner Removal and Replacement

a. Unscrew the tubing nut from the pilot tubing connection at the gas valve. Disconnect the

thermopile from the connection on the gas valve.

b. Unscrew and remove the two screws that attach the pilot assembly to the fryer tank. Lift

the entire pilot assembly out of the fryer.

c. To replace the pilot assembly, reverse the procedure.

4.1.5 Pilot Orifice Replacement

a. Remove the pilot assembly as described in 4.1.4.
b. Unscrew the tubing nut from the pilot tubing connection at base of the pilot burner. The

pilot orifice is located inside the tubing connection.

c. Remove the orifice and replace with the new orifice. Ensure the orifice is tight enough to

prevent gas leakage around the orifice.

d. Replace the tubing nut in the pilot tubing connection and tighten enough to prevent gas

leakage.

e. Replace the pilot assembly and adjust the pilot flame as described below.

4.1.5.1 Pilot Flame Adjustment - The pilot flame should be adjusted to produce the proper millivolt
output from the pilot sensing device. Millivolt output for the thermopile should be between 300 and
500 millivolts. Figure 4-1 shows the pilot assembly with examples of the incorrect and correct pilot
size. Example A illustrates a pilot flame size that is too small to produce sufficient millivolt output.
Example B is the correct size for proper millivolt output.

4-2

Figure 4-1 Pilot Assembly, Flame Adjustment

a. This test requires a DC millivolt meter set to a scale of 0-l000mv.
b. Locate the thermopile wires coming from the thermostat/High Limit box going to the

gas shut off valve. The wire insulation size decreases near the gas valve connections.

c. Connect the negative (-) test probe to pilot bracket.
d. Connect the positive (+) test probe to one of the High Limit terminal connections

e. Remove the pilot flame adjustment cover.

Figure 4-2 Gas Valve Showing Location of the Pressure Regulator and Pilot Adjusters

f. Turning the flame adjusting screw clockwise lowers the flame and the millivolt output.

Turning the screw counterclockwise increases flame size and millivolt output.

4-3

g. Rotate the screw in the direction to achieve a reading of 400 ±50 mv for thermopiles.

NOTICE

Allow 3 to 5 minutes between flame adjustments to allow the reading to settle.

h. Replace the pilot flame adjusting screw cover.

4.1.6 Thermopile Replacement

a. Remove the pilot assembly as described in 4.1.4.

b. Unscrew and remove the thermopile from the pilot assembly.

c. Remove from gas valve magnet.
d. Insert the new thermopile in the pilot assembly.

e. Replace the pilot assembly and adjust the pilot flame as described in 4.1.5.1.

4.1.7 Thermostat Replacement

The thermostat includes the temperature adjustment knob, temperature sensor inside the fryer tank,
and connecting capillary tubing. The high limit control also has a temperature sensor in the fryer
tank, so ensure you are removing the correct temperature sensor.

CAUTION

Thermostat capillary tubing is very delicate. Be VERY CAREFUL when
working with the capillary tubing. If the tubing is kinked or broken the
thermostat is no longer usable.

a. Drain the oil from the fryer and remove the heat tube screens. The thermostat probe (heat

sensor) is clamped to the heat tube inside the tank. Unscrew and remove the two screws in
the thermostat probe clamp.

b. Remove the thermostat probe from the clamp and straighten the capillary tubing. Unscrew

the small hex nut inside the cabinet under the tank for the thermostat control.

c. Unscrew the large connector nut from the tank and pull the thermostat probe and capillary

tubes through the opening.

d. Pull the knob off of the thermostat. Remove the two slot head screws from the retaining

plate.

4-4

e. Remove the two hex head screws that hold the thermostat control unit in the fryer cabinet.

f. Remove the tubing from the fittings on the thermostat body. Remove the defective thermostat

control unit from the fryer.

g. Install the new thermostat following the above procedures in reverse order. Remember to be

careful with the capillary tubes.

h. Use appropriate pipe joint compound on the large fitting before installing to prevent oil leakage.

DO NOT use joint compound on the small nut.

i. Perform the calibration procedures detailed in section 4.1.9.

4.1.8 Limit Control Replacement
The limit control includes a temperature sensor inside the fryer tank, control unit inside the fryer cabinet,

and connecting capillary tubing. The high limit control temperature sensor looks like the thermostat
temperature sensor, so ensure you are removing the correct temperature sensor clamp.

CAUTION

The limit control capillary tubing is very delicate. Be VERY CAREFUL when
working with the capillary tubing. If the tubing is kinked or broken the limit control
is no longer usable.

a. Drain the oil from the fryer and remove the heat tube screens.

b. The limit control probe (heat sensor) is clamped to the heat tube inside the tank. Unscrew and

remove the two screws in the probe clamp.

c. Remove the probe from the clamp and straighten the capillary tubing. Unscrew the small hex nut

inside the cabinet at the bottom of the tank for the limit control.

d. Unscrew the large connector nut from the tank and pull the pr obe and capillary tubes through the

opening.

e. Remove the two mounting screws from the limit control bracket and remove the limit control

unit. Disconnect the wires from the limit control box.

f. Reverse the procedure to install the new limit control.

g. Use appropriate pipe joint compound on the large fitting before installing to prevent oil leakage.

DO NOT use joint compound on the small nut.

4-5

4.1.9 Calibrating the GS Thermostat
To calibrate this thermostat the knob must be removed from the shaft. The adjustment for the

thermostat is inside the shaft.

a. Set the thermostat dial to 325°F.
b. Remove the thermostat knob by pulling the knob straight out. DO NOT rotate the knob.

c. Hold the outside of the shaft so it does not move. Use the tip of a small, flat tip screw

driver to scrape away the sealing compound from the adjustment screw. Turn the
adjustment screw clockwise to lower the temperature setting and counterclockwise to
raise the temperature. One quarter turn will change the temperature approximately 25°F.

d. Turn the adjustment until the burners turn off at 325°F. Replace the knob and allow the

fryer to cycle 4 to 6 times. Check the temperature of the thermometer against the
thermostat knob, if it is greater than 5°P repeat the calibration procedure.

e. When the calibration is correct, remove the thermometer and replace the tube screen.
