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 holds five standard
12" x 20" x 2½" steamer pans.
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
HY-5G
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.
(2)HY-5GF
The second water connection can reduce treated
water requirements.
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.

and it may not be installed within 12 inches of a
heat source, as stated in the Caution above.
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.
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).

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.
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.

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.
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
2. Water Connection(s)
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).
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.
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.
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.
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
3. Drain Connection
Separate, individual electrical connections
will be required for each steamer in the stack.
Each Steamer must have its own branch
circuit protection.
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.
C. Gas Connection
A 2 inch ID hose may be attached to the drain
pipe (supplied).
Separate gas connections are required for each
steamer in the stack. Gas supply must be
adequate under all conditions as listed on
page 6.
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A
BUILDING DRAIN. BLOCKING THE DRAIN IS
HAZARDOUS.

OM-HY-5G
D. Drain Connection
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.
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.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR VERY HOT WATER.

from the interior and exterior of the unit.
a. Set the timer to the desired time for
timed steaming.
2. Make sure the water supply line is open.
b. Turn the timer knob to the manual ON
position for continuous steam.
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 front access
panel on the right side of the unit.
c. Let the unit stay at standby temperature.
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.
WARNING

a green light - on the pilot switch 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
10. If the HY-5G Steamer behaves as described,
the unit is functioning correctly and ready for
use.
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 for a few seconds
while the pilot is re-ignited. 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.
seconds to achieve pilot ignition.
NOTE: See Automatic Operation of Pilot at
the end of this section.
7. Once the pilot burner flame has been
established (the green light on the pilot
switch is on), press the “ON” switch for the
desired steamer cavity. The steam
generator will fill with water.
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: The door MUST be closed for the
main (high) burner to work.
NOTE: For operation at high altitudes (2000 feet and
above) please consult the Groen Food Service
