GAS COOKERS GPC, GPCB, GPCR AND GPCRB
SERVICE AND PARTS
CHAPTER 1: SERVICE PROCEDURES
1.1 Functional Description
The GPC, GPCB, GPCR and GPCRB Gas Cookers all have a 12.7-gallon (48.1-liter) stainless steel
cookpot. The water in the cookpot is heated by a high-efficiency infrared heating system that
requires approximately 43% less energy than conventional burner systems to heat the same volume
of water.
Two self-contained burners are located beneath the cookpot. Each burner is fitted with special
ceramic tiles that are heated by the burning of a forced air/gas mixture. The tiles transfer their heat
to the cookpot by means of infrared radiation, providing much more constant and uniform heat
dispersion over the surface of the cookpot than do conventional burners. Because relatively less heat
is lost to the atmosphere in the process, compared to “open-burner” designs, less fuel is required to
achieve and maintain a given cookpot temperature.
Gas flow to both of the burners is regulated by one electromechanical gas valve.

Operational control of the burner system is accomplished through a solid-state SMS III Spaghetti
Magic controller. NOTE: The SMS III controller used in this model series is identical in
appearance to the SMS III controllers used in other model series, but differs internally. Use only the
part numbers listed in Chapter 2 when replacing controllers on this equipment.
