Equipment Description
Your Groen HY-5G or (2)HY-5G HyPerSteam Convection Steamer is designed to give years of service. It has a stainless steel cavity (cooking chamber) which is served by an independent atmospheric steam generator which is gas-heated. A powerful blower circulates the steam in the cavity to increase heating efficiency.
Each cavity holds up to five steam table pans (12" x 20" x 2½" deep). An 18 gauge stainless steel case encloses the cavity, the steam generator and the control compartment that houses electrical components. Door hinges are reversible (the door may be set to open from the left or right). Operating Controls are on the front panel.
The HY-5G steamer is equipped with fully electronic controls and a button-activated, pre-programmed CLEAN cycle. These units are readily identified by their unique control panels. The On-Off switch is operated by touch pad controls, and the distinctive symbol for steam is integrated into the panel.
The drain system on all models includes a spray condenser, which helps keep steam from escaping from the chamber and cools drain water.

Water Quality and Treatment
It is essential to supply the steam generator with water that will not form scale. Even though the steam generator/boiler is engineered to minimize scale formation, scale development depends on the hardness of your water and the number of hours you operate the equipment each day.
Most water supplies contain minerals which form scale. It is this scale which could lead to an early component failure.
Your local water utility can tell you about the minerals in your water. The water going to the steam generator should have between 30 and 40 parts per million (ppm) total dissolved solids (TDS) and should have a pH (acidity rating) of 7.0 to 9.0. Please follow these simple precautions:
1.The best way to prevent scale is to use a Groen PureSteem™ Water Treatment System which has been specifically designed for Groen steamers and combination ovens. Do not rely on unproven water treatment systems sold for scale prevention and removal. They are not specifically designed to work with Groen steamers and combination ovens.
2.A well-maintained water treatment system and a regular cartridge replacement schedule is essential.
3.Using a Groen PureSteem™ Water Treatment System will provide longer steam generator/boiler life, higher steam capacity, and reduce maintenance requirements.
4.If you notice a slowdown in steam production or an increase in deliming, have the steamer checked for scale build-up. This could be an indication that the water treatment cartridges need replacing. Heavy scale reduces the unit’s ability to boil water, and can even cause component failure.
MINIMIZE SCALE PROBLEMS BY INSTALLING AND MAINTAINING A GROEN PureSteem™ WATER TREATMENT SYSTEM AND BY DELIMING THE STEAMER REGULARLY.
The Groen HY-5G Steamer features two separate water inlets — one for the steam generator/boiler (treated water), the other for the spray condenser (untreated water). The second intake will reduce treatment requirements resulting in significant savings.
The dual water connections are side by side on the rear of the unit. When seen from the back of the unit, the treated water intake is on the left.

Installation and Start-Up
WARNING
THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK WITH GAS, ELECTRICITYANDPLUMBING. IMPROPERINSTALLATIONCANCAUSEINJURYTOPERSONNELAND/OR DAMAGE TO THE EQUIPMENT. THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH APPLICABLE
CODES.
CAUTION
DO NOT INSTALL THE UNIT WITH THE RIGHT OR LEFT SIDE VENTS BLOCKED OR WITHIN12 INCHES OF A HEAT SOURCE (SUCH AS A BRAISING PAN, DEEP FAT FRYER, CHARBROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL THE UNIT FRONT TO BACK, OR PITCH IT SLIGHTLY TO THE REAR.
A. Installation
The HY-5G steamer is suitable for installation on or near both combustible and noncombustible surfaces. Minimum installation clearances are:
Right Side |
2 inches |
Left Side |
2 inches |
Rear |
6 inches |
However, for easy service at least 12 inches clearance is required for the right side of the unit, and it may not be installed within 12 inches of a heat source, as stated in the Caution above.
The unit must be installed in a well-ventilated room with an adequate air supply. The steamer must be installed beneath a ventilation hood, since gas combustion products exit the appliance.
Any item which might obstruct or restrict the flow of air for combustion and ventilation must be removed. Do not obstruct the flue cover or any front, side, rear, or top vents after installation.
The area directly around the appliance must be cleared of all combustible material. The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, latest edition, including the following:
The unit and its individual shutoff valve must be disconnected from the gas supply system during any pressure testing of that system at test pressures in excess of ½ PSI (3.45 kPa). It must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSI (3.45 kPa).
1.Electrical Supply Connection
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in through hole on the lower left back panel. Each cavity requires a separate cord for connections. Local codes and/or the National
Electrical Code should be observed in accordance with ANSI/NFPA 70-1987 (or latest edition). AN ELECTRICAL GROUND IS REQUIRED. The electrical schematic is located in the service compartment and in this manual. Maximum load is 2½ AMPs. In Canada, provide electrical service in accordance with the Canadian Electrical Code, CSA C22.1 Part 1 and/or local codes.
2.Gas Supply Connection
Connection to the gas supply can be completed with ½” NPT pipe or approved equivalent. Although the immediate connection to the appliance is ½” NPT, gas supply piping must be large enough to provide 62,000 BTU/hr/cavity. Supply pressure must be at least 4.5” W.C. (maximum 14” W.C.) for natural gas or 12” W.C. (maximum 14” W.C.) for LP gas. In Canada, the installation must conform to the Canadian Gas Code, CAN 1-B149, Installation Codes for Gas Burning Appliances and Equipment and/or local codes. Check all gas connections for leaks prior to unit operation.
6
After the unit has been connected to the gas supply, all gas joints must be checked for leaks.
No flame should be used when checking for leaks. A thick soap solution or other suitable leak detector should be used.
For a unit on casters, complete connection to the gas supply with connectors that comply with the standard for connectors for moveable gas appliances, ANSI Z21.69 — latest edition. Restrain movement of the unit by attaching a cable or chain to the eyelet (provided at the back of the frame) and anchoring the cable or chain to the wall or floor. Make the length and location of the cable such that the unit cannot pull on the gas connection while the cable is connected.
2. Water Connection(s)
Install a check valve to prevent back flow in the incoming cold water line, as required by local plumbing codes. Water pressure in the line should be between 30 and 60 PSIG and must deliver a flow rate of 1.5 to 3.0 gallons per minute. If pressure is above 60 PSIG, a pressure regulator will be needed.
¾ inch female NH connectors (garden hose type) are used to attach the water supply to the inlet valves. One connector is for the steam generator (treated), the other is for the spray condenser (untreated). Minimum inside diameter of the water feed line is ½ inch. Use a washer in the hose connection. Do not allow the connection to leak, no matter how slowly. Do not over tighten hose connections. Treated (softened) water goes to the right (seen from the rear of the unit), and untreated water to the left. Connections for both are made as shown on Page 5. Though not recommended, an adapter to use a single water intake is available, P/N 138473.
3. Drain Connection
Level the steamer front to back, or pitch it slightly to the rear (maximum ¼ inch) by adjusting the optional legs or bullet feet on optional stand.
A 2 inch ID hose may be attached to the drain pipe (supplied).
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN. BLOCKING THE DRAIN IS HAZARDOUS.
OM-HY-5G
There must be a free air gap between the end of the hose and the building drain. The free air gap should be as close as possible to the unit drain. There must also be no other elbows or other restrictions between the unit drain and the free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR VERY HOT WATER.
Install the drain line with a constant downward pitch.
IMPORTANT: Do not allow water traps in the line. A trap can cause pressure build-up in the cavity, which may cause the door gasket to leak.
4. Factory Stacked Units
This section is applicable only if you are installing factory-stacked units. If you plan to stack steamers yourself, whether purchasing a new one for stacking or a kit to stack two units you already own, you will require OM-HY-5G(S), RETROFIT SUPPLEMENT
(Part Number 121087).
Installing stacked steamers is similar to installing a single unit. The steamers are stacked and assembled at the factory and delivered with the water connections and drain hoses required for a single point connection.
A.Water Connection
The same water supply connection is used for both units. At the water inlet valves, ¾ inch female NH connectors (garden hose type) are used for the water supplies. There are two connections to be made. Treated water (softened) is connected to the right valve fitting (looking from the rear of the unit) and untreated water to the left fitting.
B.Electrical Supply Connection
Separate, individual electrical connections will be required for each steamer in the stack. Each Steamer must have its own branch circuit protection.
C.Gas Connection
Separate gas connections are required for each steamer in the stack. Gas supply must be
adequate under all conditions as listed on page 6.

OM-HY-5G
D.Drain Connection
Steamers must be leveled front to back, or pitched to the rear (maximum ¼ inch) by adjusting the bullet feet on the stand.
A 2 inch ID hose may be attached to the unit drain. It must be rated for very hot water.
WARNING
DONOT CONNECT THEUNIT DRAINDIRECTLY TO THE BUILDING DRAIN.
Ensure that there is a free air gap between the end of the unit drain and the building drain. This gap should be as close as possible to the unit drain. Do not allow elbows or restrictions between the unit and the free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR VERY HOT WATER.
