Equipment Description
Your Groen Combination Oven is a stainless steel cooking chamber consisting of an air
heating compartment with fan, a boilerless steam generator, and a control compartment
which houses electrical components.
All major components of the Combination Oven are encased in a heavy duty stainless
steel cabinet. The cabinet is lined with thick ceramic insulation. A
removable drip tray is located beneath the door.
Operator controls are located on the right front of the unit, except for the manual gas
shut-off valve, which is on the back left side near the top of the of the unit.
Standard controls let you operate the unit in any one of four cooking modes:
1. As a convection oven
2. As a self-contained pressureless steamer
3. As a combination oven-steamer with low humidity
4. As a combination oven-steamer with high humidity
Cooking chamber size and pan capacities are:
10 steam table pans (12 x 20 x 2½”)
or 10 full-size (18 x 26”) bake pans
The unit is available as single, double stack (2 high) units, and low height stand. The
optional stand must have casters.
Optional stands are available for single and double stack (2 high) units. The optional
stand must have casters. All units are intended to slide under a kitchen hood installed
with 78” clearance to floor.
Controls and monitoring displays for cooking times, operating mode and temperature
selection are on the control panel. The upper portion of the panel has a text information
display. Below it are the touch pads, indicator lights, temperature and time selector knobs
and displays, the power ON/OFF switch, and an hour meter to log operating hours.
A digital readout shows the selected temperature, which is entered by turning a knob.
Another digital readout shows the remaining time on an electronic ‘kitchen timer.’ The
time is adjusted by turning a dial knob.
2 wash spray nozzles on the rear inside wall of the unit sprays the interior walls as part
of the semi-automatic cleaning system.
The air heating space is separated from the cooking chamber by removable rear and
bottom partitions. The compartment which contains the unit’s automatic controls and
other electrical components is on the right side of the unit, and is accessed by removing
the right outside panel.

Equipment Description
The bottom partition prevents food particles from falling into the water reservoir of the
boilerless steamer. Excess water and food particles falling down are collected on this
partition. A water drain is located under the removable bottom partition. Boilerless
reservoir water and cleaning water drains from the permanent floor to the stainless steel
drain pipe outside the oven. The drain pipe includes a spray condensor which suppresses
any steam escaping from the chamber and a drain box.
The unit is provided with two air and steam vents. One is to prevent internal pressure
build-up. This vent pipe exit is located at upper left corner of the unit (just above the rear
partition) and is visible from the rear of the unit. The other steam vent is from the drain
line on lower rear right and is attached to the water and overflow drain. This allows any
steam from the drain water to exhaust above the oven top. Both of these vents must be
exhausted above the oven flue and located underneath a kitchen vent hood.

Inspection & Unpacking
CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND
CAN SNAP BACK WHEN CUT.
CAUTION
THIS UNIT IS VERY HEAVY. YOU SHOULD
GET HELP AS NEEDED AND USE MATERIAL
HANDLING EQUIPMENT TO REMOVE THE UNIT
FROM THE SKID AND MOVE IT TO ITS PLACE
OF INSTALLATION.
Your Combination Oven will be completely assembled in a carton and attached to a skid.
On receipt, inspect the carton and crate carefully for exterior damage.
Carefully cut the straps around the carton and detach the sides of the carton from the skid.
Pull the carton up off the unit. Be careful to avoid personal injury or equipment damage
from nails and sharp pieces of wood or staples which might be left in carton walls.
Write down the model number, serial number and installation date and keep this information
for future reference. Space for these entries is provided at the top of the Service Log in
the back of this manual.
When starting installation, use material handling equipment to lift the unit straight up off
the skid. Check packing materials to make sure loose parts are not discarded with the
material.

Water Quality and Treatment
CAUTION
A FILTER SUITABLE FOR REMOVING FERRITE
COMPOUNDS IS RECOMMENDED WHEN THE
WATER SUPPLY HAS HIGHER THAN 50 PPM
OF IRON CONTENT. FAILURE TO DO SO COULD
CAUSE RUSTING OF THE OVEN CAVITY.
It is essential to supply the steam generator with water that will not form scale. Even
though the boilerless steam generator 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 PureSteam™ Water Treatment
System which has been specifically designed for Groen steamers and combination
ovens. Do not rely on unproven water treatments 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 water treatment system will provide longer steam generator/boiler
life, higher steam capacity, and reduce maintenance requirements.
Standard water connections for steam
generator and drain spray condenser.
4. If you notice a slowdown in steam production, check the unit’s bottom 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
WATER TREATMENT SYSTEM AND BY DELIMING THE STEAM GENERATOR/BOILER
REGULARLY.
Groen Combination Ovens features two separate water inlets — one for the steam
generator (for treated water), the other for the spray condenser (untreated water) and
semi automatic wash cycle. The second intake will reduce water treatment requirements
resulting in significant savings.
The dual water connections are on the rear of the unit.

Steam Free Zone: The Combination Oven can be damaged by steam from
external sources. Do not install the unit steam venting drain. Ensure that steam is
not present in an area bounded by the footprint of the unit and a circle 18 inches
in radius about the right and left rear corner of the unit (see figure to the left).
Install and operate the gas appliance in a well ventilated area. Adequate air must
be supplied to replenish the air used for combustion. Ventilation must employ a
vent hood and exhaust fan with no direct connection between the vent duct and
the combination oven flue. Installation must conform with local codes and/or with
the National Fuel Gas Code, ANSI Z223.1/NFPA-54 (latest edition) or the Natural
Gas and Propane Installation Code CSA B 149.1 as applicable.
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 rear vents after
installation.

THE AREA DIRECTLY AROUND THE APPLIANCE MUST BE CLEARED OF ALL
COMBUSTIBLE MATERIAL. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
CAUSE BODILY INJURY AND/OR PROPERTY DAMAGE.
NOTE: The unit must be installed on a stand with casters.
The unit must be disconnected from the gas supply system during any pressure
testing of that system which has test pressures in excess of ½ psi (3.45 kPa).
The unit 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 (3.5 kPa).
