OM-AH/1 5
AH/1 steam kettles are stainless steel, floor mounted kettles with a self-contained
steam source heated by gas. A closed steam jacket covers the lower portion of the
kettle. Heat from the gas burner boils water in the jacket to produce steam under
pressure. To ignite the burners, the kettle uses electronic spark ignition.
The kettles are stationary (non-tilting). Liquids can be removed through the tangent
draw-off valve.
Exposed surfaces are stainless steel. Insulated sheathing protects the kettle body, and
a housing encloses the controls. Three tubular legs support the unit. Bullet feet adjust
to level the kettle.
A one piece dome cover is hinged to the kettle on the 20-gallon model. Covers for 40,
60, 80, and 100-gallon kettles are supplied with counterbalancing spring actuators to
hold the covers in the fully open or closed position.
Controls provided include the ON/OFF switch, to control electric power for the unit, and
the thermostat, to set the cooking temperature. The automatic controls and a brief
description of each are as follows.
1. Gas pressure regulator: Protects the unit from high pressure in the gas supply
line.
2. Automatic gas valves: Allow gas into the burners as needed.
3. Pressure limit switch: Turns off the burner when jacket pressure reaches 27 PSI.
Lights the burner when pressure drops to 22 PSI.
4. Safety valve: Lets steam out of the jacket if the steam pressure exceeds 30 PSI.
5. Low-water cutoff: Turns off the burner if the water level in the jacket gets too
low for safe operation.
Instruments also are provided to show what is happening inside the unit. These are:
1. Water level sight glass: Indicates whether there is enough water in the steam
jacket.
2. Pressure/vacuum gauge: Shows steam pressure, and whether too much air has
entered the jacket.
3. Heating indicator light: Indicates that the kettle is being heated.
4. Power on indicator light: Glows when the unit is turned on.
5. Low water indicator light: Lights to show that jacket water needs to be
replenished.
