The Gas and Electrical Power Supplies

The main indicators that the gas or electrical power supply is the cause of ignition failure are as follows: 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 hose 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.

The Electronic Circuits

If the fryer is receiving gas and electrical power, the next most likely cause of ignition failure is a problem in the 24 VAC circuit of the pilot system. If the fryer is equipped with a drain valve for filtration purposes, check the drain valve to verify that it is fully closed. A microswitch attached to the valve must be closed for power to reach the gas valve. Often, although the valve handle appears to be in the closed position, the microswitch is still open. If the valve is fully closed, or the fryer is not equipped with a filtration system, refer to Troubleshooting the 24 VAC Circuit in Section 1.7.1 of this manual.

The Gas Valve

If the problem is not in the 24 VAC circuit of the pilot system, it is most likely in the gas valve. However, before replacing the gas valve, refer to Troubleshooting the Gas Valve in Section 1.7.2 of this manual.

Improper Burner Function

In these types of instances, the burner ignites but exhibits abnormal characteristics, such as popping, incomplete lighting of the burner, fluctuating flame intensity, and flames “rolling” out of the fryer.

Popping indicates delayed ignition. In most cases, the main gas valve is opening, but the burner is not immediately lighting. When ignition does take place, excess gas bursts into flame suddenly, rather than smoothly igniting.

The primary causes of popping are:

1.Incorrect or fluctuating gas pressure

2.Misdirected or weak pilot flame

3.Clogged burner orifices

4.Inadequate make-up air

5.Missing or misaligned burner deflector targets

6.Clogged vent tube (causing incorrect gas pressure).

Incorrect or Fluctuating Gas Pressure

If popping occurs only during peak hours, the problem may be incorrect or fluctuating gas pressure. Verify that the incoming gas pressure (to the gas valve) is in accordance with the appropriate CE or non- CE standard found in the table on Page 1-4 and the pressure remains constant throughout all hours of usage. Refer to Checking the Burner Manifold Pressure in Section 1.3.2 for instructions on checking the pressure of gas supplied to the burner.

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.
