Groen AH/1E-20 User Manual

Equipment Description
Groen Models AH/1 and AH/1E steam kettles are stainless steel, floor mounted kettles with a self-contained
steam source heated by gas. A closed steam jacket covers the lower 2/3 of the kettle. Heat from gas flames
boils water in the jacket to produce steam under pressure. To ignite the flames, Model AH/1 has a
continuously burning pilot flame, called the standing pilot, and Model AH/1E has electronic spark ignition.
The kettles are of the stationary (nontilting) type. Liquids can be removed from the kettle through the tangent
draw-off valve.
All exposed surfaces are stainless steel. An insulated canopy protects the kettle body, and a housing
encloses all the controls.
Three tubular legs support the unit. Bullet feet on the legs can be adjusted to level the kettle.
A one piece dome cover is hinged to the kettle. Covers for 60, 80, and 100 gallon kettles are supplied with
counterbalancing actuators to hold the covers in the fully open or closed position.
Controls used by the operator 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 are listed below.
Gas pressure regulator: Protects the unit from high pressure in the gas supply line
Automatic gas valves: Let gas into the burners at the proper time
Pressure limit switch: Closes the main automatic gas valve when steam pressure in
the jacket reaches 27 PSI and opens the valve when the
pressure drops to
22
PSI
Safety valve: Lets steam out of the jacket if the steam pressure gets too high
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 the operator what is happening inside the unit. These instruments
are:
Water gauge glass: Indicates whether there is enough water in the steam jacket
Pressure/vacuum gauge: Shows the steam pressure and whether too much air has got
into the jacket
Heating indicator light: Indicates that the kettle is being heated
The kettle body is welded into one piece and furnished with a rim reinforced by a rectangular bar. The interior
of the kettle is polished to a 180 emery grit finish, while the exterior is given a bright semi-deluxe finish. The
unit is ASME shop inspected and registered with the National Board for working pressures up to 30 PSI.
The standard 2 inch tangent draw-off is a 316 stainless steel, compression disc valve. A removable strainer
with 1/4 inch holes keeps pieces of product that are too large from going down into the drawoff.
The jacket is filled at the factory with water containing rust inhibitors. The kettle can operate at steam
pressures up to 30 PSI, which provide kettle temperatures of 150 to 270°F. This temperature range allows
the operator to use the kettle for warming, simmering, boiling, or braising.
For AH kettles, options include:
1. Larger (3 inch) draw-offs
2. Plug-type draw-off valves (not NSF approved)
3. Solid disc strainer or strainer with 1/8 inch perforations
4. Electronic spark ignition
5. Fill faucet
6. Automatic, metered water filler (Gallon Master)
7. TRI-BC basket inserts
8. Kettle brush kit
9. Etch marks
10. Flanged feet
