H50 SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES Functional Description H50 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.
The H50 Series of fryers has been in production since 1983. Consequently, servicers are likely to encounter three different interface board designs. Although the boards differ slightly in appearance, basic functioning and electrical connections are the same from one to another.
Page 8
** See Probe Resistance Chart at end of chapter. *** 5 mega-Ohms or greater. These standard interface boards are also used in a number of fryer types besides the H50 Series. The information contained in this section applies to H50 Series applications ONLY.
(setpoints). The temperatures are programmed by means of a keypad on the face of the controller. H50 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.
Checking the Burner Manifold Gas Pressure 1. On non-CE fryers, ensure that the gas valve knob is in the OFF position. Honeywell 2. Remove the pressure tap plug from the gas valve assembly. Pressure Tap Plug Typical Non-CE Typical CE Valve Valve Assembly Assembly 2.

Measuring Flame Current When the burner flame is properly adjusted, it will produce a current between 2.5 μA and 3.5 μA. Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing wire on the ignitor. This is accomplished as follows: 1.
7. Disconnect the ignition cables from the ignitors by grasping the boots and gently pulling toward you. 8. Remove the component box mounting screws. 9. Rotate the top of the component box out of the frame and carefully pull it out enough to disconnect the wiring harness plug(s) from the back of the box.
5. Reverse the procedure to install the replacement module. 1.6.5 Replacing an Ignitor Assembly DANGER Drain the frypot or remove the handle from the drain valve before proceeding further. 1. Disconnect the fryer from the electrical supply. 2. Disconnect the ignition cable from the ignitor by grasping the boot and gently pulling toward you.
Page 15
Remove these fasteners. (On black-colored FASCO blowers there are three nuts. On silver-colored KOOLTRONICS blowers there are three screws.) 3. Wrap the motor with plastic wrap to prevent water from entering it. Spray degreaser or detergent on the blower wheel and the blower housing. Allow it to soak for five minutes. Rinse the wheel and housing with hot tap water, then dry with a clean cloth.
Page 16
Left Viewing Port is Behind Motor Right (NOTE: Blower Viewing shield omitted Port for clarity.) The air/gas mixture is properly adjusted when the burner manifold pressure is in accordance with the applicable table on page 1-6 and the burners display a bright orange-red glow. If a blue flame is observed, or if there are dark spots on a burner face, the air/gas mixture requires adjustment.
Adjusting Air/Gas Mixture CE Units Built Through April 1999 CE units built through April 1999 are equipped with a shield assembly in front of the blowers. An air shutter plate on the face of the shield assembly regulates the amount of airflow to the blower in- take.
1.6.8 Replacing a Burner Assembly DANGER Drain the frypot or remove the handle from the drain valve before proceeding further. 1. Disconnect the unit from the electrical and gas supplies. 2. Remove the combustion air blower per the procedure found in Section 1.6.6. 3.
15. Examine the burner flame. The color and intensity on both sides should be the same. 16. Use an inspection mirror to check for leaks in areas that cannot be directly observed. 17. If a leak is detected, tighten all the lower insulation retainer nuts, allow the frypot to run for five additional minutes, and repeat steps 15 and 16.
16. Carefully lift the frypot from the fryer cabinet. 17. Remove the drain valve(s), temperature probe(s), high-limit thermostat(s), and ignitor assemblies. Inspect each of these components carefully and install them in the replacement ® frypot if they are in serviceable condition. Use Loctite PST56765 sealant or equivalent on component threads.
Page 21
10. Remove the flue assembly (10). 11. Remove the upper burner rails (11). NOTE: For the following steps, refer to the frypot exploded view on page 3-19 for component iden- tification. 12. Remove any residual insulation, sealant, and/or oil from the exterior of the frypot. 13.
Page 24
21. Insert the burners (9) into the rails to ensure the rail spacing and alignment are correct. The burner should slide freely into and out of the rails. The upper rail can be bent slightly to increase or decrease tension on the burner, and the edges of the slot can be closed or opened slightly to best fit the burner frame.
33. Install the upper oil-zone insulation (21) by pressing it under the upper combustion chamber metalwork. Secure the insulation with the bracket (22) and ¼” self-tapping screws. 34. Install the upper burner rail blanket insulation (23). Position any excess insulation toward the top of the frypot.

PROBLEMS RELATED TO THE GAS AND/OR ELECTRICAL POWER SUPPLIES The main indicators of this are that an entire battery of fryers fails to light and/or there are no indicator lights illuminated on the fryer experiencing ignition failure. Verify that the quick disconnect fitting is properly connected, the fryer is plugged in, the main gas supply valve is open, and the circuit breaker for the fryer electrical supply is not tripped.
Page 27
If popping occurs only during peak operating hours, the problem may be incorrect or fluctuating gas pressure. Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the appropriate table below, and that the pressure remains constant throughout all hours of usage. Refer to Check Burner Manifold Pressure in the section of 1.4 for the procedure for checking the pressure of gas supplied to the burner.
Page 28
If all other causes have been ruled out, examine the burner tiles for any signs of cracking. If cracks are found, the burner must be replaced. Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pressure, but may also be the result of variations in the kitchen atmosphere.

325ºF (163ºC) point by pressing button and entering the code 1652. The test results will be displayed in the computer’s LED panel in minutes and seconds. The maximum acceptable recovery time for the H50 Series of fryers is two minutes and twenty-five seconds.
1.7.5 Filtration Problems 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. 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.
Page 31
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will not melt or prevent solidification of shortening in the pan. Blockage removal can be accomplished by forcing the item out with an auger or drain snake.

1.7.7 Basket Lift Malfunctions H50 Series fryers may optionally be equipped with automatic basket lifts to ensure uniform cooking times. Basket lifts will always come in pairs, although each operates independently of the other.
Page 35
A bell crank style basket lift consists of a cam and bell crank that are connected to the basket lift arm by a flat metal link. The cam is attached to a drive motor. The motor ro- tates the cam, thus raising or lowering the lift arm linked to the bell crank.
An additional set of operator troubleshooting guides is contained in Chapter 6 of the H50 Series Installation and Operation Manual (P/N 819-5000). It is suggested that service technicians thoroughly familiarize themselves with both sets.
