H50 SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.1 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. Self-contained combustion chambers (referred to as “burners”) are fitted into rails attached to the sides of the frypot, one on each side. Each combustion chamber is fitted with specia

the other leg of the heat relay coils, which then close electronic switches in the 24 VAC circuit to provide current to the ignition module. Circuitry in the ignition module sends 24 VAC to the gas valve via a normally closed high-limit switch (and, in fryers with built-in filtration systems, 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 ignition by measuring the flow of

THERMOSTATS All fryers in the H50 Series have temperature probes located on the front centerline of each frypot. (Dual-vat frypots have two probes, one in each vat.) In this type thermostat, the probe resistance varies directly with the temperature. That is, as the temperature rises, so does resistance, at a rate of approximately 2 ohms for every 1º F. Circuitry in the controller monitors the probe resistance and controls burner firing when the resistance exceeds or falls below pr

1.5 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. Place the fryer power switch in the OFF position. 2. Disconnect the sensing wire from one of the burner ignitors and connect it to the positive lead of the meter. Connect the negative lead of the meter to t
