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 & Treatment
It is essential to supply the steam generator with water that will not form scale or cause
corrosion. Even though the steam generator is engineered to minimize scale formation
and the effects of corrosion, their development depends on the quality of your water and
the number of hours per day you operate the equipment.
Most water supplies are full of minerals and chemicals which are not suitable for use in
a steam generator.
Gas
Connection
REAR VIEW
Untreated
Water
Drain
Water quality varies from state to state and city to city. It is necessary that you know
and understand the quality of the water you are using. Your water utility can tell you
about the minerals and chemicals in your water. The water going to the steam generator
should be within these guidelines
Water Pressure 30-60 psi
PH 7 to 9
Hardness less than 60 ppm
TDS 30 to 60 ppm
Chlorine and Chloramine less than 0.1 ppm
Total Chloride less than 30 ppm
Silica less than 12 ppm
Undissolved Solids less than 5 microns
1. Do not rely on unproven water treatments which are sold for scale prevention or
scale removal. They don’t always work. The best way to prevent scale is to supply
the purest possible water (30 - 60 ppm TDS).
2. If your water contains scale-forming minerals, as most water does, use a wellmaintained water softener. Whether an exchangeable softener cartridge or a
regenerating system is chosen, a regular exchange schedule is essential.
3. Installing a water meter between the softener and the steamer will provide an
accurate gauge of water use, and will help determine when to exchange cartridges
or regenerate the softener. Using a water softener will provide longer generator life,
higher steam capacity, and reduce maintenance requirements.
6 OM-HY/5G
4. If you notice a slowdown in steam production, have the unit checked for scale
build-up. Heavy scale reduces the unit’s ability to boil water and can even cause
heating elements in the steam generator to overheat and burn out

IMPROPER INSTALLATION CAN CAUSE
INJURY TO PERSONNEL AND/OR DAMAGE
TO THE EQUIPMENT. THE UNIT MUST BE
INSTALLED IN ACCORDANCE WITH
APPLICABLE CODES. THE UNIT MUST BE
INSTALLED BY A LICENSED PLUMBER OR
GAS FITTER WHEN INSTALLED WITHIN THE
COMMONWEALTH OF MASSACHUSETTS.
CAUTION
DO NOT INSTALL THE UNIT WITH THE RIGHT
OR LEFT SIDE VENTS BLOCKED OR WITHIN
12 INCHES OF A HEAT SOURCE (SUCH
AS A BRAISING PAN, DEEP FAT FRYER,
CHARBROILER OR KETTLE). TO AVOID DRAIN
PROBLEMS, LEVEL THE UNIT FRONT TO
BACK, OR PITCH IT SLIGHTLY TO THE REAR.
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 1/2
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 1/2 PSI (3.45 kPa).
1. Electrical Supply Connection
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring conduit in through open
frame on the under-side of cabinet. 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 2
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 1/2” NPT pipe or approved
equivalent. Although the immediate connection to the appliance is “ NPT, gas
supply piping must be large enough to provide 62,000 BTU/hr. 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. 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.

Installation
WARNING
DO NOT CONNECT THE DRAIN DIRECTLY
TO A BUILDING DRAIN. BLOCKING THE
DRAIN IS HAZARDOUS.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR VERY HOT WATER.
3. Water Connection
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.
4. 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). 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. 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.
Proper Drain Line Connection - Drain Line must
have a constant downward pitch of at least 1/4”
per foot. (2)HY-5G shown.
5. 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 8.
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. 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. Install the line with a constant downward pitch.
OM-HY/5G 9
Initial Start-Up
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY
FROM STEAM COMING OUT OF THE UNIT.
THE STEAM CAN CAUSE BURNS.
Automatic Operation of Pilot
Once the pilot burner is lit, it essentially
functions as a standing pilot. In this state,
if the pilot is accidentally extinguished (by
a very strong gust of wind for example), it
will re-ignite automatically. The unit will
completely shut down. Operator must turn
off and then back on to reset. Then the unit
will come back on and resume operation in
the mode and with the (running) timer value
existing just prior to shutdown. The pilot
switch may be turned off during “off hours”
to conserve energy.
After the unit has been running, if the pilot
burner ever fails to re-ignite automatically
within 90 seconds, wait 5 minutes before
you attempt to reactivate it. In the unlikely
event that ignition problems persist, contact
your authorized Groen Service Agency.
NOTE: For operation at high altitudes (2000
feet and above) please consult the Groen
Food Service Engineering Department.
After the HY-5G Steamer has been installed, test it to ensure that the unit is operating
correctly.
Remove all literature and packing materials from the interior and exterior of the unit.
1.
2. Make sure the water supply line is open.
3. Make sure that the gas supply line is open and that the manual knob on the
main gas valve is turned to the “on” position. This valve is located behind the
access panel on the right side of the unit.
4. Turn on electrical service to the unit. The HY-5G will not operate without
electrical power. Do not attempt to operate the unit during a power failure.
5. The steamer will not operate until the pilot burner has been ignited. To light the
pilot burner, activate the pilot switch located next to the main gas valve. When
the pilot ignition sequence has been successfully completed, a green light - on
the pilot switch (old models) - and on the electrical panel (new models) will glow.
6. The “trial for ignition” period is roughly 90 seconds. If the pilot burner does not
light within about 90 seconds after the switch is activated, the ignition system
automatically stops gas flow to the pilot burner and stops the ignition trial. If
this happens, turn off the pilot switch and repeat the trial for ignition. During
the initial start-up, the pilot may require several trials for ignition until all the air
is bled from the gas piping. Subsequent start-ups should require only about 5
seconds to achieve pilot ignition.
NOTE: See Automatic Operation of Pilot at left.
7. Once the pilot burner flame has been established (the green light on the pilot
switch (old models) or electrical panel (new models) is on), press the “ON” switch
for the desired steamer cavity. The steam generator will fill with water.
NOTE: The door MUST be closed for the main burner to work.
10 OM-HY/5G
8. When the steam generator has filled with water, the burners will ignite
automatically. Within approximately 8-10 minutes the READY light will come on,
indicating that the water has reached its standby temperature. When the READY
light is displayed, you may take any one of the following steps:
a. Set the timer to the desired time for timed steaming.
b. Turn the timer knob to the manual ON position for continuous steam.
c. Let the unit stay at standby temperature.
9. To shut down the unit, press the ON switch into the off position. The steam
generator will then drain. You may also switch off the pilot switch to conserve
energy.
10. If the HY-5G Steamer behaves as described, the unit is functioning correctly and
ready for use.
