MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS

CHAPTER 1: SERVICE PROCEDURES

1.9.2 Improper Burner Functioning

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 this condition, the main gas valve is opening but the burner is not immediately lighting. When ignition does take place, the excess gas "explodes" into flame, rather than smoothly igniting.

The primary causes of popping are:

•Incorrect or fluctuating gas pressure

•Misdirected or weak pilot flame

•Burner deflector targets out of alignment or missing

•Clogged burner orifices

•Inadequate make-up air

•Clogged vent tube, causing incorrect gas pressure

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 CE or Non-CE standards found in the tables on Pages 1-5 and 1-6, and that the pressure remains constant throughout all hours of usage. Refer to Section 1.3 for the procedure for checking the burner gas pressure.

If popping is consistent during all hours of operation, verify that the pilot is properly positioned above the burner orifice and that the pilot pressure is correct. Correct pilot pressure is indicated by a flame 1 to 1-½" (25 to 38 mm) long. Refer to Section 1.4 for the pilot flame adjustment procedure.

Clogged burner orifices, especially those near the pilot, are also likely causes of delayed ignition. Clogged orifices are indicated by no flame, flames that are orange-colored, and flames that shoot out at an angle from the rest.

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 when the door is opened to the kitchen and a rush of incoming air is felt, this indicates that more air is being exhausted than is being replenished and the burners may have insufficient combustion air.

If the fryer’s gas and air supplies are okay, the problem most likely is with one of the electrical components. Examine the computer for signs of melting/distortion and/or discoloration due to excessive heat buildup in the fryer. (This condition usually indicates improper flue performance.). A discolored or distorted computer should be replaced immediately. To prevent recurring problems, correct the condition immediately.

The burner lighting on one side only may be caused by a missing or misaligned rear deflector target or improper burner manifold pressure. Clogged burner orifices are usually the cause of gaps in burner firing.
