24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

24G Series Flatbottom gas fryers contain a welded steel frypot (mild steel) with heat-transfer ducting on the frypot bottom for efficient heating of oil without scorching. A draft inducer draws air over the burners for combustion. Air movement directs the combustion products back and forth across the frypot bottom by means of a set of baffles, transferring the heat evenly. Cold air is prevented from entering the combustion chamber and cooling the oil during the coasting cycle.

Flames originate from orifices in three tubular burners positioned beneath the frypot. The diameter of the orifices differs for Natural (CE:G20/G25) and LP (CE:G31) gas as indicated in the table below.

An electromechanical gas valve regulates gas flow to the manifold. 24G Series Flatbottom gas fryers are equipped with either a 120-volt valve system (standing pilot) or a 24-volt valve system (electronic ignition or CE standing pilot). Units may be configured with either a pilot ignition system (standing pilot) or an electronic ignition system (direct spark ignition).
