  • Page 15 DO NOT apply compound to the first two threads. This will ensure that the burner orifices and control valve do not become clogged. 2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A soap solution should be used for this purpose.

  • Page 16: Converting To Another Gas Type

    Converting to Another Gas Type Your fryer is configured at the factory for either natural gas or propane (LP) gas. If you desire to switch from one type of gas to another, a gas conversion kit must be installed by a Factory Authorized Service Center technician.

  • Page 17: Frypot Boil-Out

    In addition, after the fryer has been in use for a period of time, a hard film of caramelized vegetable oil will form on the inside of the frypot. This film should be periodically removed by following the boil-out procedure.

  • Page 18: Chapter 3: Service Procedures, Troubleshooting And Wire Diagrams

    CHAPTER 3: SERVICE PROCEDURES, TROUBLESHOOTING AND WIRING DIAGRAMS Functional Description H52 Series fryers contain a welded stainless steel frypot that is directly heated by a high efficiency infrared burner system requiring approximately 43% less energy than conventional burners to cook the same volume.
  • Page 19 Circuitry in the ignition module sends 24VAC to the gas valve via a normally closed high-limit switch (and, in BIH52 fryers, a normally closed drain safety switch). Simultaneously, the module causes the ignitor to spark for 4 seconds to light the burner. A flame sensor verifies the burner is lit by measuring the flow of microamps through the flame.

    The temperatures are programmed by means of a keypad or knob on the face of the control- ler. H52 Series fryers are also equipped with a high-limit thermostat. In the event that the fryer fails to properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to the flash point.

    3.6.4 Replacing an Ignition Module 1. Disconnect the fryer from the electrical supply. 2. Remove the screws from the upper corners of the control panel and swing the panel open from the top, allowing it to rest on its hinge tabs.
  • Page 28 A sheet metal shield or shield assembly prevents inadvertent access to the blower assembly. The specific design varies depending upon the particular configuration of the fryer and the country for which manufactured, but in all cases, the shield is attached to the cabinet framing by sheet metal screws.
  • Page 29 5. Reinstall the blower shield or shield assembly. 6. Light the fryer in accordance with the procedure described in Chapter 3, Section 3.1. 7. After the burners have been lit for at least 90 seconds, observe the flames through the burner viewing ports located on each side of the combustion air blower.
  • Page 30 Non-CE Units and CE Units Built After April 1999 On the side of the blower housing opposite the motor is a plate with one or two locking nuts. Loosen the nut(s) enough to allow the plate to be moved, then adjust the position of the plate to open or close the air intake opening until a bright orange-red glow is obtained.

  • Page 31: Replacing A Gas Valve

    3. Remove the four nuts from the air plenum assembly and pull the assembly straight out toward you until it clears the burner tubes. NOTE: On a dual vat fryer, it will be necessary to remove the drain valve handles before the plenum can be removed.

  • Page 32: Replacing The Frypot

    NOTE: Use P/N 826-0931 for full vat frypots and P/N 826-0932 for dual vat frypots. 13. Reverse steps 1 through 9 to reassemble the components. 14. Fill the frypot with oil. Turn the fryer on, turn off or bypass the melt cycle, and operate the unit for at least 10 minutes.
  • Page 33 10. On BIH52 units, remove the cover from the safety drain switch, disconnect the wires from the switch, and pull them out of the switch box. 11. On BIH52 units, remove the section(s) of square drain from the drain valve(s) of the frypot to be removed.

  • Page 34: Replacing Frypot Insulation And/Or Upper Burner Rails

    3.6.10 Replacing Frypot Insulation and/or Upper Burner Rails NOTE: Replacing the burner rails requires completely tearing down the frypot and installing new frypot insulation. Refer to the frypot exploded view on page 3-18 for component identification. 1. Remove the frypot per Section 3.6.9. 2.

    24VAC circuit. If the fryer is equipped with a built-in filtration system (BIH52 models), first verify that the drain valve is fully closed. (The valve is attached to a mi- croswitch that must be closed for power to reach the gas valve. Often, although the valve handle ap- pears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the...
  • Page 40 If the fryer’s gas and air supplies are okay, the problem is most likely with one of the electrical com- ponents. Examine the ignition module and controller for signs of melting/distortion and/or discol- oration due to excessive heat build-up in the fryer.
  • Page 41 Check for proper operation by disconnecting the wire from the ignitor (spark plug), inserting the tip of a screw driver into the terminal, and holding it near the frame of the fryer as the power switch is placed in the ON position. A strong, blue spark should be generated for at least 4 seconds.
  • Page 42 LOCK CLEARED. 3.7.5 Filtration Problems BIH52 units are equipped with FootPrint III built-in filtration systems. The majority of filtration problems arise from operator error. One of the most common errors is placing the filter paper on the bottom of the filter pan rather than over the filter screen.
  • Page 43 Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of the filter paper, including that the correct size is being used. While you are checking the filter pa- per, verify that the O-ring on the bottom of the filter pan is present and in good condition. A missing or worn O-ring will allow the pump to suck air and decrease its efficiency.
  • Page 44 Improperly sized or installed paper will also allow food particles and sediment to pass through and clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction tube may indicate that the crumb tray is not being used. Pan blockage can also occur if shortening is left in the pan and allowed to solidify.

    and miscellaneous standard black metal fittings for connections. This design allows oil/shortening to bypass the pump as it drains from the oil return lines back into the filter pan when the system is turned off. Bypassing the pump expedites draining of the lines. The pump solenoid leads are con- nected to Pins 7 and 9 of the upper 9-pin plug assembly.
