EQUIPMENT DESCRIPTION
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 (75.7 liters)
model. Covers for 40 and 60-gallon (151.4 and 227 liters) 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.
