The HY-6G (CE) has two independent cavities, each
with its own base-mounted steam generator.
Equipment Description
Your Groen HY-6G (CE) HyPerSteam Convection Steamer is designed to give years of
service. It has two stainless steel cavities (cooking chambers) which are served by
twin, independent atmospheric steam generators which are gas-heated. A powerful
blower circulates the steam in each cavity to increase heating efficiency.
Each cavity holds up to three steam table pans (305 x 508 x 64 mm). A 1.5 mm
stainless steel case encloses the cavities, the steam generators and the control
compartment that houses electrical components. Door hinges are reversible (the doors
may be set to open from the left or right). Operating Controls are on the front panel.
HY-6G (CE) steamers are equipped with fully electronic controls and a buttonactivated, pre-programmed CLEAN cycle.
The drain system includes a spray condenser, which helps keep steam from escaping
down the condensate drain.

Water
Water Quality & Treatment
It is essential to supply the steam generator with water that will not form scale.
Even though the steam generator is engineered to minimize scale formation, scale
development depends on the hardness of your water and the number of hours the
equipment operates.
In some areas of the country, water is low enough in minerals to avoid scale formation.
But most water supplies are full of minerals which form scale. It is this scale which could
lead to an early component failure.
Your water utility can tell you about the minerals in your water. The water going to the
steam generator should have between 10 and 30 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. Do not rely on unproven water treatments which are sold as scale prevention or
scale removers. They don’t always work. The best way to prevent scale is to supply
the purest possible water (10 - 30 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 system is essential.

Connection

Water
Drain
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.
4. If you notice a slowdown in steam production, check the unit 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.
5. 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.
MINIMIZE SCALE PROBLEMS BY USING AND MAINTAINING A SOFTENER, AND BY
CLEANING THE STEAMER REGULARLY.

Left Side 0 mm (0 inches)
Rear of Flue 150 mm (6 inches)
However, for easy service at least 300 mm (12 inches) clearance is required for the
right side of the unit, and it may not be installed within 300 mm (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
The unit is designed for connection to fixed wiring. A suitably rated isolating
switch with contact separation of at least 3 mm on both poles must be fitted
to the installation. Wiring must be executed in accordance with the regulations
listed on page 2 of this manual.

5. Burner Air Adjustment
The unit is equipped with fixed aeration type burners which have no provision for
air inlet adjustment.
6. Equipotential Terminal
In accordance with national regulations, each unit is fitted with an equipotential
terminal.
7. Water Supply Connection (Treated Water)
The HY-6G CE model is fitted for a 3/4 inch B.S.P.T. cold water connection. The
water supply must be provided at a rate of not less than 2.7 liters (0.70 gallons)
per minute. Pressure must be 2.0 to 4.0 Bar (30 to 60 PSI) maximum.
Water quality minimums require totally dissolved solids (T.D.S.) of 30 parts per
million maximum, and a water pH of 7.0 or greater. If the available water supply
fails to meet these requirements, water treatment equipment must be provided
to ensure steamer reliability and operating life.
CAUTION
DO NOT USE PLASTIC PIPE. THE DRAIN MUST
WITHSTAND HOT WATER.
Install a WRAS approved double-check valve or an equally effective back-flow
preventive device in the incoming cold water line at the point of connection(s)
to the steamer and in compliance with all local plumbing codes. This installation
must be per WRAS-IRN R160 Schedule 2-15(1). For units with the dual water
connection option, a double-check valve shall be installed on each water line.
Do not allow the connection to have any leak, regardless of how small.
8. Untreated Water Second Connection
As discussed previously, the flow of water used for steam suppression in
the drain is much greater than the amount of water used to generate steam.
The second connection on steamers (see illustration under “Water Quality &
Treatment” section) permits the installer to supply treated water to the steam
generator and untreated water to the drain. With “split water” feature, the initial
fill requirement for treated water is 3.5 U.S. gallons (19 L) within 2.5 minutes.
The requirement for treated makeup water is 0.12 gallon (0.45 L) per minute per
cavity. A field retrofit kit is available for single water connection if required.
9. Drain Connection
The HY-6G (CE)Steamer must be leveled front to back. A 38mm (1½ inch) ID
hose may be attached to the drain pipe (supplied) by means of a hose. DO NOT
CONNECT THE HOSE DIRECTLY TO A BUILDING DRAIN. 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 any water traps in the line. A trap can cause pressure to
build up inside the cavity during steaming, which will make the door gasket leak.

Initial Start-Up
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY
FROM STEAM COMING OUT OF THE UNIT.
THE STEAM CAN CAUSE BURNS.
After the HY-6G(CE) 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 front access
panel on the right side of the unit.
4. Turn on electrical service to the unit. The HY-6G(CE) 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 at the lower front, next to the main gas valve.
When the pilot ignition sequence has been successful, 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 seconds to achieve
pilot ignition. Reinstall panel(s). 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 electrical
panel is on), press the ON/OFF touch pad for the desired steamer cavity. The steam
generator will fill with water.
NOTE: The door MUST be closed for the main (high) burner to work.
8. When the steam generator has filled with water, the main and low burners will ignite
automatically. Within 6-8 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.
To shut down the unit, press the ON/OFF touch pad into the off position. The steam
9.
generator will then drain. You may also switch off the pilot switch to conserve energy.
10. If the HY-6G(CE) Steamer behaves as described, the unit is functioning correctly and
ready for use.
10 OM-HY/6G(CE)
Initial Start-Up
11. 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.
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.
12. Gas Type Conversion (See Paragraph 3 on page 9 for important information for gas
conversion. Verify the type of gas to be used).
To change the type of gas used (e.g. G20 to/from G31) change the following:
Burner injector, Pressure setting on Main Gas Valve, Data plate, Gas pressure
Regulator Springs
The governor spring does not need to be changed; only the pressure setting.
ALL CONVERSIONS MUST BE FOR APPROVED GAS IN THE COUNTRIES LISTED IN

A. Controls
Operator controls are on the front right of the unit. The control panel has the
following touch pads and indicator lights. (Your controls may have either words
or the symbols shown below):
• The ON/OFF touch pad gets the HyPerSteam ready for use, or shuts it off.
• The READY indicator light shows that the steam generator is at standby
temperature and the cavity is hot enough to begin steaming.
• The CLEAN indicator lights when the unit is operating in the cleaning mode.
• The SERVICE indicator light shows when the water level probes have stopped
working, and need to be cleaned (normally an indication of lime deposits).
When one probe is not working, the SERVICE light flashes briefly every few
seconds. When both probes fail, the light will flash continuously and the
beeper will sound.
• The HI TEMP indicator light comes on when the steam generator is too hot.
The unit will automatically shut off, and cannot be turned on again until it has
been serviced.
• The CLEAN touch pad is used to start the automatic 50 minute cleaning cycle.
The timer is used in three ways:
1. In the OFF position the steam generator stays at a low boil or “holding”
temperature.
2 When a cook time is set, the unit steams until the timer reaches OFF. The
steaming stops, a red light comes on and a beeper sounds.
3 With the timer turned to the ON position, the unit steams continuously. The
green light stays lit. The steamer will not time down.
Gas Lockout Indicator and Reset Control:
Should the pilot fail to ignite during start-up, a yellow indicator on the control
panel (see page 11) will light and the supply of gas to the unit will be halted.
12 OM-HY/6G(CE)
When this occurs, the ignition process may not be started again for five minutes.
After that time, press the Lockout Reset Switch located behind the front panel
and attempt to start the unit again. If the lockout continues to occur after three
attempts, contact your Groen Service Agency for assistance.
B. Operating Procedure
1. Press the ON/OFF touch pad for the steamer. The steam generator will fill,
and heat until the READY light comes on. (About 10 minutes.)

same levels, and be even on top. The maximum allowable weight of food is
9.8 kilograms (21.6 lbs.) per pan.
3. Open the door and slide the pans onto the supports. If you will only be
steaming one pan, put it in the middle position.
4. Close the door. With the READY indicator lit, take one of the following steps:
• If you want to steam the food for a certain length of time, set the
timer for that period. The timer will automatically run the steamer for
the set time and then turn it off. A red light will come on and a beeper
will sound. Steam production stops.
• To steam continuously, turn the timer to the manual ON position. A
green light will come on. The unit will continue steaming until you
stop it by turning the timer to OFF. When steaming continuously YOU
MUST CONTROL STEAMING TIME.
5. Open the door. Remove the pans from the steamer, using hot pads or oven
mitts to protect your hands from the hot pans.
6. To shut down the unit, press the ON/OFF touch pad OFF. The steam
