CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

Decathlon Series gas fryers contain a welded steel frypot (stainless or cold-rolled) that is heated by
gas flames diffused evenly through tubes built into the frypot.
Flames originate from orifices in a burner manifold positioned beneath cast-iron burners. The
burners are positioned in the tube openings, at the front of the frypot. The diameter of the orifices
differs for natural (CE:G20/G25) and LP (CE:G31) gas as indicated in the accompanying table.
