Misdirected or Weak Pilot Flame

If popping is consistent during all hours of operation, check position of the pilot above the burner orifice and verify that the pilot pressure is correct. A 1- to 1 ½-inch (25 to 38 mm) flame indicates correct pilot pressure. Refer to Section 1.3.3 for information on pilot flame adjustment.

Clogged Burner Orifices

Clogged burner orifices, especially those near the pilot, are also likely causes of delayed ignition. Lack of flame, flames that are orange in color, and flames that shoot out at an angle from the rest are indications of clogged burner orifices. If only one side of the burner is lighting, the rear deflector target may be misaligned or missing completely. Improper burner pressure may also cause this. If there are gaps in burner firing, check for clogged burner orifices.

Inadequate Make-up Air

Another cause of popping is an insufficient air supply or drafts that are blowing the pilot flame away from the burner. Check for negative pressure conditions in the kitchen area. If air is flowing into the kitchen area, this indicates that more air is entering the kitchen than is leaving it. In a negative pressure environment, the burners may not be receiving an adequate amount of air to maintain a strong pilot flame.

Other Causes of Popping

Other causes of popping are more ambiguous and may have two or more possible causes to consider.

If the fryer’s gas and air supplies are okay, it is likely that the cause of the popping is one of the electrical components. Examine the controller for signs of melting, distortion, and possibly discoloration due to excessive heat buildup in the fryer (usually indicating improper flue performance). Automatically suspect a discolored or distorted controller and replace it. However, it is important to diagnose and correct the condition causing excessive heat in the fryer or the problem is likely to recur.

Fluctuating flame intensity is normally caused by improper or fluctuating gas pressure or the result of variations in the kitchen atmosphere. Verify incoming gas pressure in the same way as for popping, discussed in the preceding paragraphs. Air condition and ventilation units (such as hoods) starting and stopping throughout the day usually cause variations in the kitchen atmosphere. As they start and stop, the pressure in the kitchen may change from positive or neutral to negative, or vice versa. They may also cause changes in airflow patterns that may affect flame intensity.

Flames “rolling” out of the fryer are usually an indication of negative pressure in the kitchen. The negative air pressure is sucking air out of the fryer enclosure and the flames are following the air. If negative pressure is not the cause, check for high burner manifold gas pressure in accordance with the procedures in Section 1.3.2. An obstructed flue, which prevents the fryer from properly exhausting, may also be the cause.

An unusually noisy burner, especially when flames are visible above the flue opening, may indicate that the burner gas pressure is too high or that the gas valve vent tube is blocked. If the gas pressure is correct and the vent tube is unobstructed, the gas valve regulator is probably defective.

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.
