OM/SM-HY-12GF(CE) & HY-24GF(CE)
Drain Connection with Drain Box
rate of not less than
7.6 liters (two
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.
Install a WRAS approved double-check valve or an
equally effective backflow preventive device in the
incoming cold water line at the point of connnection(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.
1.5 Drain Connection
The unit must be leveled front to back or pitched
slightly to the rear (one to two degrees) by
adjustment of the bullet feet on the cabinet base. All
units are shipped from the factory with a drain box
and vent pipe.
The drain box and vent pipe provide the necessary
air gap when properly installed. The illustrations at
right shows proper installation of drain lines.
Leave a air gap to any building drain. Do NOT
create any water traps in the drain line. A trap could
cause pressure to build up in the cavity during
steaming and cause the door gasket to leak.
WARNING
VARIATION FROM THESE INSTRUCTIONS CAN
CREATE A HAZARD.
DO NOT USE PLASTIC PIPING — DRAIN MUST
WITHSTAND VERY HOT WATER.
1.6 Initial Start-Up
After the HY-12GF(CE) Steamer has been installed, test
it to be sure that it is operating correctly.
1. Remove all literature and packing materials from
the interior and exterior of the unit.
2. Make sure the water supply line is open.
3. Make sure the gas supply line is open and that
the gas shut-off valve in the unit is in the OPEN
position. This valve is located behind an access
panel on the right side of the unit
4. Turn on electrical service to the unit. The unit
will not operate without electrical power. Do not
try 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 next to the main gas
valve. (See photo below). When the ignition
sequence is successful a green light on the
electrical panel will glow.

8 OM/SM-HY-12GF(CE) & HY-24GF(CE)
OM/SM-HY-12GF(CE) & HY-24GF(CE)
6. The “trial for ignition” period is roughly
90 seconds. If the pilot burner does
not light within 90 seconds, the system
automatically stops gas flow to the pilot
burner and lights the Lockout neon on
the front control panel. If this happens,
turn off the pilot switch, push the Gas
Reset switch, and repeat the trial for
ignition. During the first start-up, the
pilot may require several trials for
ignition to bleed air from the piping.
Subsequent start-ups should only need
about five seconds to achieve pilot
ignition. NOTE:See Automatic Pilot
Operation at the end of this section.
7. Once the pilot flame has been
established (the green light on the
electrical panel 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
(high) heater to work.
8. When the steam generator has filled with water,
the main and low burners will automatically light.
The READY light should come on within 10
minutes, to show that the water has reached its
standby temperature. When the READY light is
on, the operator may take any of the following
steps:
a. Set the timer to the desired time for timed
steaming.
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY FROM
STEAM COMING OUT OF THE UNIT. THE STEAM
CAN CAUSE BURNS.
b. Turn the timer knob to the manual ON
position for continuous steam.
c. Let the unit wait at standby temperature. The
steam generator is equipped with a high-limit
thermostat which will trip if the liquid level
probe fails.
9. If this happens, the High Temperature neon on
the front control panel will glow and trip a reset
switch. The Reset Switch must be pressed to
re-start steam generation. This switch is located
next to the pilot switch (towards the rear of the
unit) and can be reached through the access
door on the right side of the unit.
10. To shut down the unit, turn the ON switch to the
OFF position. The steam generator will
automatically drain. You may also switch OFF
the pilot switch to conserve energy
11. If your steamer works as described, it is
functioning correctly and is ready for use.
Automatic Pilot Operation
Once the pilot burner has been lit, it essentially
functions as a standing pilot. When the pilot switch
is on, if the pilot is accidentally extinguished (by a
very strong gust of wind or the like), it will re-ignite
automatically. The unit will shut off completely for a
few seconds while the pilot is re-ignited. The unit will
then come back on and resume operation in the
mode and at the (running) timer value existing just
prior to shutdown. The pilot switch may be turned off
during “off hours” to conserve energy.
If the pilot burner ever fails to re-ignite automatically
within 90 seconds, after the unit has been running,
the Gas Lockout neon on the front control panel will
light. Wait five minutes and push the Gas Reset
switch to reignite the pilot. Should ignition problems
persist, contact your authorized Groen Service
Agency.
1.7 Setting the Gas Pressure
1. During commissioning, a gas pressure check is
essential. Connect a suitable pressure gauge to
the gas manifold to perform this test. The
pressure gauge should be connected to the test
nipple (See photograph at right).

OM/SM-HY-12GF(CE) & HY-24GF(CE) 9
OM/SM-HY-12GF(CE) & HY-24GF(CE)
Adjust Gas Pressure by Turning the Screw inside the
Gas Pressure Adjustment Turret.
To test pressure, attach a pressure gauge to the test
nipple on the gas manifold.
2. Turn the main gas and electricity supply on.
3. Light the burners as described in Paragraph 1.6
above.
4. Manifold gas pressure should be as noted in
Section 1.3.1 of the manual. If adjustment is
necessary, follow steps below.
5. Remove the governor cap screw on the gas
control valve to gain access to the screw inside
the turret. (See photograph).
6. The governor is suitable for both natural and
propane gas.
7. Turn the screw inside the turret clockwise to
increase the pressure, anti-clockwise to reduce
it. Check the burner pressure again after 15
minutes operation, and adjust if necessary.
8. Disconnect the pressure gauge from the test
point. Reseal the test point and test for gas
soundness.
9. Replace governor cap screw, and replace
control box panel and lid.
NOTE:For operation at high altitudes (1000 meters and
above) consult the Groen Food Service
Engineering Department.
1.8 Instructions to User
IMPORTANT: After installing and commissioning the
appliance, the User’s Instructions should be handed
to the user or purchaser. Ensure that the
instructions for lighting, turning off, correct use and
cleaning are properly understood. Emphasize the
location of the main gas isolating valve and
demonstrate the emergency shut down procedure.

2. Servicing and Conversion
CAUTION
BEFORE ATTEMPTING ANY SERVICING, ENSURE THAT THE ISOLATING COCK IS TURNED OFF AND CANNOT
BE INADVERTENTLY TURNED ON. CHECK THAT THE ELECTRICITY SUPPLY IS DISCONNECTED.
AFTER ANY MAINTENANCE TASK CHECK THE APPLIANCE TO ENSURE THAT IT PERFORMS CORRECTLY AND
CARRY OUT ANY NEEDED ADJUSTMENTS AS DETAILED IN SECTION 1.
AFTER CARRYING OUT ANY SERVICING OR EXCHANGE OF GAS CARRYING COMPONENTS ALWAYS CHECK FOR
GAS SOUNDNESS.
Conversion
To change from natural gas to propane gas or vice
versa, change the following:
• Burner injectors (high fire orifices)
• Rimner Tube Injector (low fire orifice)
• Pilot orifice
• Pressure setting
• Data Plate
The governor spring does not need to be changed —
only the pressure setting.
After Servicing
1. Test for gas soundness as specified in IGE/UP1
as appropriate after any gas connection has
been disturbed.
2. Check for correct operation (see Commissioning
of Appliance)
2.1 Assembly/Disassembly Procedures
GENERAL INFORMATION
The procedures which follow are based on having full
access to the steamer on all four sides. If the steamer is
installed between other appliances and there is not
enough room on the sides for access, it must be puled
out from its position. Exercise care when moving the
steamer to avoid stress or pull on electrical, water and
gas connections.
2.1.1 Right Side Panel (Louvered) — Removal
P/N 123196
1. With a flat blade screwdriver, remove the two
10-32 screws on the lower edge of the panel.
The panel is retained to the steamer by an
interlocking guide track on the top edge and
three spring-like clips at the rear edge.
2. Once the screws are removed, SLIDE the panel
toward the front of the appliance with a lifting
motion. Do not attempt to pry the panel. Once
the panel is clear of the rear clips, it may be lifted
off of the top rack.
ASSEMBLY TIP: When replacing the panel, press the
rear edge inward so that all three clips are retained by
the back flange. Make sure that the holes in the panel
align with the two tapped holes in the steamer so that
replacing the screws will be easy and will not damage the
threads.
2.1.2 Left Side Cover — Removal
Left P/N 123197
Under normal conditions, the left side cover should never
have to be removed, since there are no operational or
replacement parts to be accessed. The single exception
occurs when the door has been reversed so that the
handle is on the left and the Door Interlock Switch
requires replacement. The door switches for both door
positions are installed at the factory, so there is no need
to have access to them if the door is to be reversed.
1. If the left side cover is to be removed because of
a faulty door switch, remove the right side panel
first. Using a 7mm nut driver and the flat blade
screwdriver, remove the retaining clip and the
two screws on the lower edge of the left side
cover. The assembly may then be slid forward.
Once clear of the retaining clip, it may be lifted
off.
ASSEMBLY TIP: When replacing the left cover
assembly, be sure that the retaining clip is replaced and
screwed down tightly.
2.1.3 Water Inlet Valve — Three Way
P/N 090827
1. Turn off power and water supply to the steamer.
2. Remove the water supply hose connection on
the rear of the steamer.
3. Remove the right side panel, as described in
Paragraph 2.1.1, above.
