PERFORMANCE PRO SERIES GAS FRYERS MODELS 35 & 45

CHAPTER 1: SERVICE PROCEDURES

1.1 General

Performance Pro Series gas fryers (formerly Master Jet 35- and 45-series fryers) contain a welded stainless steel frypot directly heated by gas flames diffused evenly over its lower surface by ceramic targets. The flames originate from orifices in a U-shaped burner manifold positioned beneath the frypot. They are equipped with either a millivolt gas valve or electromechanical gas valve that regulates gas flow to the manifold. For operating information, refer to the Performance Pro Series Gas Fryers Models 35 & 45 Installation and Operation manual (P/N 819-6042). (Furthermore, referred to as the Installation and Operation manual.)

1.1.1 Pilot Ignition

The pilot system is the pilot orifice, pilot hood, and thermopile. The pilot serves two purposes: lighting the burners and heating the thermopile. In operation, the thermopile is in contact with the pilot flame and generates millivolts. The millivolt output passes through a normally closed high-limit switch and energizes the gas valve pilot coil, which opens the pilot valve. If the pilot flame is extinguished, the gas valve pilot coil loses voltage and the pilot valve closes.

In units equipped with 24-volt electromechanical gas valves, a separate 24-volt circuit activated by the fryer power switch provides voltage through the thermostat or controller to the gas valve main coil, which opens the main valve. The main gas valve will not open if the pilot valve is not open. Light the pilot flame manually using a match or the optional built-in piezo ignitor after installing the fryer.

1.1.2 Electronic Ignition

In units configured for electronic ignition, an ignition module connected to an ignitor assembly replaces the pilot system. The ignition module performs three important functions: supply voltage to the gas valve, provide an ignition spark, and proof the pilot flame. The module contains a 4-second time delay circuit and a coil that activates the gas valve. The ignitor assembly consists of a spark plug, a pilot, and a flame sensor element.

At start-up the power switch is placed in the ON position, supplying 12 VDC to the heat control circuitry in the controller or computer and to one side of the heat relay coil on the interface board. If resistance in the temperature probe indicates the temperature in the frypot is below 180°F (82°C), the current flows through a melt cycle circuit where a timer switch alternately closes for 3 seconds and opens for 24 seconds. If the temperature is 180°F (82°C) or above, the current flows through a heat circuit, bypassing the timer switch. In either case, current is supplied to the other leg of the heat relay coil, which closes an electronic switch in the 24 VAC circuit to provide current to the ignition module.

Circuitry in the ignition module sends 24 VAC current to the gas valve via a normally closed high-limit switch and a drain safety switch. Simultaneously, the module causes the ignitor to spark for 4 seconds to light the pilot flame. A flame sensor verifies that the pilot is lit by measuring the flow of microamps through the flame. If the pilot does not light or is extinguished, current to the ignition module is stopped, preventing the main valve from opening, and the ignition module locks out until the power switch is turned OFF, then back ON.

45, 35 specifications

The Frymaster 35 and 45 series fryers are well-known in the catering industry for their reliability, efficiency, and advanced cooking technologies. These models are designed to cater to medium to high-volume establishments, providing users with exceptional performance and ease of use.

One of the main features of the Frymaster 35 and 45 series is their impressive fry capacity. The 35 model can handle around 35 pounds of oil, while the 45 model accommodates up to 45 pounds. This increased oil capacity means that both fryers can fry larger batches of food more efficiently, allowing for quicker service times in busy kitchens.

Another key characteristic is the high-performance heating elements. The Frymaster series utilizes V-shaped heat exchangers, which deliver rapid recovery times and consistent cooking temperatures. This technology enables the fryers to maintain optimal heat levels even during heavy usage, ensuring that food is cooked evenly and thoroughly.

The Frymaster 35 and 45 also feature built-in filtration systems. This technology helps in prolonging the life of the oil by filtering out food particles and impurities, which not only enhances the taste of the fried food but also reduces operational costs. The automatic filtration system can be programmed to run on a cycle to ensure that oil quality remains high without requiring constant manual intervention.

In terms of user-friendly design, both models are equipped with digital temperature controls, which allow chefs to precisely set and maintain frying temperatures. The intuitive control panel simplifies operation, while the integrated safety features, such as high-limit temperature controls, help prevent overheating and accidents in the kitchen.

Durability is another hallmark of the Frymaster series. Constructed from stainless steel, these fryers are built to withstand the rigors of commercial kitchens while resisting corrosion and wear. Additionally, Frymaster offers a range of accessories and options, such as baskets and lids, to enhance the functionality and versatility of these fryers.

In summary, the Frymaster 35 and 45 series fryers are top-tier options for commercial food establishments, combining substantial fry capacity, advanced heating technology, built-in oil filtration, and user-friendly controls. Their robust design and efficiency make them ideal for any kitchen looking to deliver high-quality fried foods consistently.
