PERIODIC MAINTENANCE
SECTION 4: MODELS: GC-2 & GC-3
Item G: Pilot Burner should remain lit at all times unless appliance will not be in use for an
extended period of time.
IF AT ANY TIKE THE FLAME SHOULD BECOME
EXTINGUISHED. A 5 MINUTE PERIOD FOR COMPLETE SHUT
OFF OF GAS SUPPLY IS REQUIRED BEFORE RELIGHTING.
Item H: Main Burners of aluminized steel tube.
FLOOR AREA BENEATH BURNERS MUST BE KEPT FREE AND
CLEAR TO PROVIDE AIR FOR COMBUSTION AND
VENTILATION.
Item I: Gas Combination Control Valve regulates flow of natural gas (or propane) to Burners.
Operation is dependent on other controls. Refer to START UP TEST RUN - SECTION 1.
Item J: Cold Water Solenoid Valve fastened to the right rear bottom of Generator Control Box
supplies cold water to condense live steam before it exhausts into the drain and is controlled by the
Thermostat (Item P).
Item K: Hot Water Solenoid Valve fastened to the bottom of Generator Control Box immediately in
Front of Item J feeds hot water to the Boiler but its functioning is entirely dependent on the Water
Level Control (Item E).
Item L: Operating Pressure Switch fastened to the inside bottom front of the Generator Control
Box is plumbed to sense the pressure in the Boiler and thence control the operating cycle of the
Gas Combination Control Valve (Item I). This switch is factory set to energize the Gas Combination
Control Valve and ignite the Main Burners at 9 psi but to de-energize the Valve and turn off
Burners at 11 ½ psi thus maintaining a pressure range in the Boiler between 9 psi to
approximately 13 psi (override considered).
Item M: Override Pressure Switch similar to and located directly behind the above switch senses
steam pressure in excess of the normal operating range which occurs only at initial Start-Up of the
Boiler at approximately 13 psi and thence energizes Solenoid Valve (Item V) to open briefly to
allow for discharge of said excess pressurized steam thence the Boiler becomes stabilized.
Item N: Power Switch fastened to the front fact of the Generator Control Box when switched ON
will automatically begin the steam generating process in the Boiler.
Item O: Pilot Light is located directly above the Power Switch and when lit (green) indicates power
is ON.
Item P: A Thermostat mounted on the back wait of the Generator Control Box has its heat
sensing capillary bulb fastened to the appliance Drain. When excessive heat (i.e. steam) comes in
contact with the bulb, the Thermostat will energize the Cold Water Solenoid Valve (Item J).
