Equipment Description

Your Groen Convection Combo™ has a stainless
steel cooking chamber, an air heating compartment
with heat exchange tubes and fan, a steam
generator, and a control compartment which houses
electrical components.  

All major components of the Convection Combo™ 
are encased in a 16 gauge stainless steel cabinet.
The cabinet is lined with 1½ to 2 inches (4 to 5 cm)
thick glass fiber insulation.  A removable drip tray is
located beneath the door.  

The door is reversible so that it may open from the
left or right. Operator controls are located on the right
front of the unit, except for the pilot control switch
and manual gas shut-off valve, which are behind the
sliding access door on the right side of the unit.

Standard controls let you to operate the Convection
Combo in any one of  three cooking modes:

1.

As a convection oven

2.

As a self-contained pressureless steamer

3.

As a combination oven-steamer

Models CC10-G and C/2-20G differ in cooking
chamber size and pan capacity:

CC10-G: 4 steam table pans (12x20x2½”), or

7 half-size (13x18") US bake pans

C/2-20G: 10 steam table pans (12x20x2½”), or

9 full-size (18x26") US bake pans

Units are supplied on a stainless steel stand.  The
smaller Convection Combo™ is available as the
single CC10-GF or the double stacked (2) CC10-GF. 
The larger unit is available as the single C/2-20GF or
the double-stacked (2)C/2-20GF. 

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 digital cooking time readout and touch pads for
setting cook times.  Below the timer section are lights
which indicate the status of the unit and touch pads
to select the mode of operation and to switch on
power.

A digital readout shows the selected temperature,
which is entered by turning a dial.  Pilot burner
status is shown by a light on the pilot ignition switch.

An insulated, gas-fired steam generator is mounted
behind the oven.  Steam enters the oven through a
connecting tube near the bottom left rear corner of
the oven.

The deliming port is located on the stand just below
the control panel.  De-liming solution goes through

this port into a fill tank, from which it is transferred to
the steam generator during the unique Groen
automatic cleaning cycle.

The air heating space which contains the heat
exchanger tubes is also separated from the cooking
chamber by removable left, right, top 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.

A drain is located in the removable bottom of the
cooking chamber.  Fluids drain from this removable
bottom and 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.
