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.
Door hinges are reversible so that doors 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.
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 CC20-G differ in cooking
chamber size and pan capacity:
CC10-G: 4 steam table pans (12x20x2½”), or
7 half-size (13x18") US baking pans
CC20-G: 10 steam table pans (12x20x2½”), or
9 full-size (18x26") US baking pans
Although some early model CC10-G units were
manufactured for counter-top installation, all units are
now 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 CC20-GF or the double-
stacked (2)CC20-GF.
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.
On single CC10-G units which were supplied without
stands, de-liming solution is added to the unit through
the port located on top of the unit, directly above the
steam generator. Units supplied with stands have a
port 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. On Convection
Combo™ units manufactured after August 1, 1991,
the drain assembly also includes a drain box.
