PERIODIC MAINTENANCE
SECTION 4:
MODELS: GC-2 & GC-3
Fig. 2: The Cabinet is the lower section of the Steamer providing not only a base for the Cooker to be positioned at a
proper working height but also the enclosure for the Gas Boiler and Controls.
THE APPLIANCE AREA MUST BE KEPT FREE AND CLEAR FROM
COMBUSTIBLES. DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATION AIR.
FRONT VIEW
Item A: Gas Boiler weldment assembly.
Item B: Safety Sensor, enclosed by the Sensor Cover Box, is a Boiler protective device which will shut off the Main
Burners when excessive heat occurs should the water level in the Boiler drop below a level sufficient to immerse and
protect the Boiler tubes, heads and shell that come in contact with direct heat from the Burners.
Item C: Handhole Cover Assembly when unbolted and removed allows internal examination and cleaning of Boiler if
required.
AT LEAST TWICE A YEAR REMOVE HANDHOLE COVER ASSEMBLY.
INSPECT BOILER INTERIOR FOR SCALANT AND LIME BUILD UP.
Item D: The Pressure Gauge is directly above and threaded to the Water Level Control. It should read '0' during shut
down and function in a range of approximately 9 to 13 p.s.i. during operation of the appliance.
Item E: The Water Level Control is a mechanical switch intended to maintain proper water level in the Boiler. A Float is
contained within the chamber of the Water Level Control and when it drops, it will trip the switch in the control and
demand sufficient water to replenish it to the proper level.
A MANUAL VALVE LOCATED DIRECTLY BELOW THE WATER LEVEL
CONTROL CHAMBER MUST BE OPENED BRIEFLY AT LEAST ONCE A WEEK
TO BLOWDOWN SEDIMENT AND SCALANT THAT MAY BE LODGED IN THE
CHAMBER. FAILURE TO DO SO MAY CAUSE EXCESSIVE
ACCUMULATION, SEIZURE OF THE FLOAT AND EVENTUAL MALFUNCTION
OF THE WATER LEVEL CONTROL.
Item F: The Water Gauge assembly has a glass tube for visual verification that water level is being maintained in the
Boiler during operation. The manual valves at the top and the bottom of this assembly must be fully open and only
closed if damage should occur to the glass tube.
OBSERVE THAT THE WATER IS CLEAN AND CLEAR IN THE GLASS TUBE.
THE APPEARANCE OF EXTREME MURKINESS IN THE WATER
INDICATES INADEQUATE WATER QUALITY AND WILL CAUSE FAILURE
OF CONTROLS AND THE APPLIANCE. WARRANTY DOES NOT COVER
MALFUNCTION DUE TO POOR WATER CONDITIONS.
