Model G-26 ovens are:
• Electrically heated
• Heated by infrared panels
• MenuSelect® Operated
§JECClrJI(Q)N Jl
JD) 1E § CC JRJIJFlrJI (Q) N
• Conveyorized
• Electronically controlled
The G-26 conveyor oven is designed for installation on acountertoporworktable that will adequately accommodate
its size and weight.
The oven employs infrared cooking technology. Infrared heat panels are placed one above and one below the
conveyor. These panels form the oven's upper and lower heat zones. AController accurately maintains set cooking
temperatures and conveyor speed (cooktime) forconsistent and repeatable results. Food is cooked by absorption of
infrared waves as it is conveyed through the oven chamber.
The oven features stainless steel exterior and an aluminized steel oven chamber. The conveyor is a 16" wide stainless
steel chain link belt. Oven operatingvoltage is dual rated 208/240 VAC, 50/60Hz, 1 phase. It is equipped with factory-
installed cord with plug conforming to NEMA Standard 6-SOP. The oven also includes a set of four 4" high NSF
approved adjustable legs, heat curtains, crumb trays and exit trays.

SECTION 1 -DESCRIPTION
2. Cooking Area
The CTX Model G-26 has a 26" (660 mm) long
cooking deck (chamber) with a 16" (406 mm) wide
conveyor belt.
3. Controller
The Controller controls both the temperature and
conveyor belt speed (cook time) of the oven. Cook
temperature can be set from 200°F to 950°F (93°C to
509°C) and cook time can be set from 01 :00 minute
to 30:00 minutes.
4. Infrared Heating Panels
Patented heating panels are positioned above and
below the conveyor belt of each oven deck (cham- ·
ber). When energized these panels emit infrared
long waves. These waves do not heat the air through
which they pass. Instead the waves are absorbed by
the outer surface of the product transported through
the oven on the conveyorbelt. Using this application
food is placed on the conveyor and the unique
properties of the infrared waves cause it to cook from
the outside to the center in traditional fashion.
5. Heat Zones
The heat zones refer to individual areas of heat
control within a cooking deck (chamber). The deck
contains two heat zones (top and bottom). Refer to
Figure 1-4.
6. Conveyor
The conveyor is used totransport the product through
the oven deck (chamber). The conveyor is made up
of a frame and a stainless steel wire belt which can
travel in either direction around the frame. The con-
veyor can travel at variable speeds and the speed is
controlled by the Controller. The speed of the con-
veyor determines how long the productwill be in the
cooking chamber which is the cooking time. The
oven chamber is 18-1/2" (470 mm) wide with a 16"
(406 mm) wide conveyor belt.
7. Accessories
Kit For Stacking Two G-26's
An accessory stacking pins kit (PIN G26STACK)
allows you to stack two G-26's one on top of the other
(See Installation Section). The pins must be used
when stacking a G-26 or the warranty is voided.
Instructionsfor stacking the ovens are also available
in the stacking bracket kit.
Kit ForStackinga SingleG-26 on Top of aToast-
master C0-19
or a Blodgett CTB-1
An accessory stacking bracket kit (PIN
ACSBG24C019) allows you to stack a single G-26
on top of aToastmasterC0-19convection oven ora
Blodgett CTB-1 convection oven (See Installation
Section). This bracket must be used when stacking
a G-26 or the warranty is voided. Instructions for
stacking the ovens are also available in the stacking
bracket kit.
