“PASTA MAGIC” GAS WATER COOKER (GWC)

SERVICE MANUAL

CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

The Pasta Magic GWC Gas Cookers 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.

Inside GPC Cabinet

Operational control of the burner system is accomplished through a simple thermostat controller for simmer and switch for boil. Ease of operation is assured through simple on/off, and boil/simmer switches. Front mounted green power light indicates when the unit is on, and front mounted amber trouble light is illuminated for over 30 seconds indicates when the unit is not functioning properly.

The module will try to light for four seconds. If unsuccessful, the blower will remain on for 15 seconds and try again. During the 15 second period the amber light will remain on. Once the burner is lit and the flame is proved, the module ends the lighting sequence and the amber light goes out. If the flame is not proved after eight tries, the module will lock out and the amber light will remain lit.

When in the BOIL mode, the burners are lit at all times. It is used when actually cooking pasta.
