C24GA SERIES CONVECTION STEAMERS - ELECTRICAL OPERATION

Hold Thermostat

The Hold Thermostat energizes the Generator Slow Fill Solenoid Valve when

 

generator temperature reaches the non-adjustable setpoint at 190°F.

Drain

The Drain is located on the lower right of the base and removes steam conden-

 

sate and water from cooking compartments and generator.

Metal Fiber Main Burner

The Metal Fiber Main Burner is accessible from the front. This burner heats the

 

water in the generator to generate steam.

Gas Combination Control Valve....

The Gas Combination Control Valve is part of the Burner Assembly and is a

 

gas solenoid that opens to allow gas flow when a call for heat is made and that

 

also regulates the manifold gas pressure.

Blower Motor

The Blower Motor is part of the Burner Assembly and provides airflow for the

 

metal fiber burner. The blower is accessible through the front of the base.

Blower Air Pressure Switch

The Blower Air Pressure Switch is part of the Burner Assembly and closes at

 

0.4" W.C. to apply operating voltage to the ignition module.

Gas Orifice

The Gas Orifice is part of the Blower Assembly and controls the flow of gas to

 

the burner.

Ignition Control Module

The Ignition Control Module controls the ignition of the gas pilot and main

 

burner.

24 VAC Transformer

The 24 VAC Transformer reduces the input 120 VAC to the 24 VAC required by

 

the Ignition Module.

Super Heater Assembly

The Super Heater Assembly (Heat Exchanger) is located at the rear of the

 

base surrounding the flue and is used to raise the temperature of the steam by

 

passing the steam around the flue assembly.

Drain Valve Timer

The Drain Valve Timer turns on for 1000 seconds when Power On/Off Switch

 

is set to off position to operate the Drain Solenoid.

5 PSI Pressure Relief Valve

The 5 psi Pressure Relief Valve opens if the generator pressure exceeds 5 psi

 

to prevent further pressure rise.
