Equipment Description
Groen Models HH/4 and HH/4E steam kettles are stainless steel, floor mounted 40 gallon kettles with a self-contained steam source heated by gas. A closed steam jacket covers the lower b of the kettle. Heat from gas flames boils water in the jacket to produce steam under pressure. To ignite the flames, Model HH/4 has a continuously burning pilot flame, called the standing pilot, and Model HH/4E 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 (a “product faucet”) at the front of the kettle.
All exposed surfaces are stainless steel. An insulated canopy protects the kettle body, and a housing encloses all the controls. A one piece dome cover is hinged to the kettle.
Three tubular legs support the unit. Bullet feet on the legs can be adjusted to level the kettle.
Controls used by the operator include the ON/OFF switch, which controls electric power for the unit, and the thermostat, which sets the cooking temperature.
Instruments are provided to show what is happening inside the unit:
•Water gauge glass: shows the level of water within the steam jacket
•Pressure/vacuum gauge: shows the steam pressure and if there is air in the jacket
•Indicator lamp: Lights when the kettle is being heated
Automatic controls within the unit:
•Gas Pressure Regulator: Adjusts gas pressure up to 14" W.C.
•Pressure Limit Switch: Turns the main burner off when steam in the jacket reaches its highest operating pressure.
•Low-water cutoff: Turns off the burner if water level in the jacket gets too low for safe operation.
•Safety valve: Releases steam if jacket pressure gets too high
The 40 gallon kettle body is welded into one piece and furnished with a rim reinforced by a rectangular bar. 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 has a removable strainer with ¼ inch holes which keep pieces of product that are too large from going down into the draw-off.
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 approximately 270°F (56 to 132ºC). This temperature range allows the operator to use the kettle for warming, simmering, boiling, or braising.
Optional equipment for the HH/4 kettles includes:
•Three inch draw-off valve
•c” perforated or solid disc strainer
•Basket inserts (TRI-BC)
•Water fill faucets
•Automatic water filler
•Kettle brush kit
•316 stainless steel liner

Installation
A. Installation
The unit should be installed in a ventilated room for efficient performance. Items which obstruct or restrict the flow of air for combustion and ventilation must be removed. The area around the appliance must be free of combustible materials.
WARNING
THE KETTLE MUST BE INSTALLED BY PERSONNEL QUALIFIED TO WORK WITH ELECTRICITY. IMPROPER INSTALLATION CAN RESULT IN INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT.
1.Installation requires connection with gas and electrical services. See items 8 to 14 for details.
2.To protect the unit from damage, leave it on the shipping pallet until installation. When installation is to begin, cut the straps holding the kettle, and hoist it straight up off the skid.
NOTICE:To avoid damaging parts of the burner system underneath the kettle, LIFT THE UNIT ONLY BY THE RING beneath the outer edge of the body.
3.Install the unit with a minimum clearance to combustible and non-combustible construction of six inches at the sides and six inches between the draft diverter and the wall. Also leave enough room for cleaning, maintenance, and service.
4.The draft diverter (flue) shipped with the kettle is the correct height and shape for maximum performance. Slide the diverter onto the flue collar at the back of the kettle and secure it with the two sheet metal screws provided.. Do not change the diverter in any way.
Any mechanical, electrical, or gas type change must be approved by the Groen Food Service Engineering Department.
WARNING
