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°Fto
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
conveyor
belt.
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
to
transport
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
product
will
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.

A.
Inspect
for
Shipping
Damage
All
shipping
containers
should
be
examined
for
dam¬
age
before
and
during
unloading.
This
equipment
was
carefully
inspected
and
packaged
at
the
factory.
The
freight
carrier
has
assumed
responsibility
for
its
safe
transit
and
delivery.
If
equipment
is
received
in
damaged
condition,
either
apparent
or
concealed,
a
claim
must
be
made
with
the
delivering
carrier.
1.
Apparent
Damage
or
Loss
-
If
damage
or
loss
is
apparent
it
must
be
noted
on
the
freight
bill
or
express
receipt
at
the
time
of
delivery,
and
it
must
be
signed
by
the
carrier’s
agent
(driver).
If
this
is
not
done,
the
carrier
may
refuse
the
claim.
The
carrier
will
supply
the
necessary
claim
forms.
2
.
Concealed
Damage
or
Loss
-
If
damage
or
loss
is
NOT
apparent
until
after
equipment
is
uncrated,
a
request
for
inspection
of
concealed
damage
must
be
made
with
carrier
within
15
days.
The
carrier
will
make
an
inspection
and
will
supply
necessary
claim
forms.
Be
certain
to
retain
all
contents
plus
external
and
internal
packaging/crating
materials
for
inspec¬
tion.
B.
Placement
of
Oven
Some
very
important
considerations
must
be
made
when
choosing
the
place
where
the
oven
is
to
oper¬
ate.
1.
This
oven
is
conveyorized
and
operates
continu¬
ously.
It
should
be
placed
so
it
fits
into
the
“flow”
of
the
operation.
2
.
Drafts
entering
the
oven
chambers
can
cause
inconsistent
cooking
results.
Check
the
area
sur¬
rounding
the
oven
and
eliminate
sources
of
drafts
such
as
open
windows
or
doors
and
fans
or
other
appliances
that
cause
air
circulation.
3.
Oven
should
be
positioned
so
hot
air
from
an¬
other
piece
of
equipment
cannot
enter
oven
cooling
fan
air
intake
on
the
control
compartment.
Serious
problems
could
occur.
NOTE:
To
validate
a
new
oven(s)
warranty
a
factory
certified
installer
must
verify
that
Steps
C

K
have
been
performed
correctly.

C.
Unpacking
Oven
The
oven
components
should
be
moved
as
close

remove
it
from

oven,
then
remove
the
empty
carton
from
the

Standoffs
If
the
back
side
of
the
oven
will
be
against
a
wall
the
four
(4)
standoffs
sup¬
plied
in
the
installation
kit
must
be
mounted
to
the
rear
panel
of
oven.
To
install
the
standoffs
re¬
move
one
rear
panel
screw
at
a
time
and
re¬
place
with
a
standoff
as
shown
in
Figure
2-8.
These
standoffs
will
keep
the
ventilation
louvers
on
the
rear
control
compart¬
ment
panel
from
being
blocked.
Placing
the
oven
directly
against
a
wall
without
the
standoffs
will
block
the
vent
louvers
and
will
not
allow
hot
ambient
air
in
the
control
compartment
to
escape.
The
compart¬
ment
would
then
overheat
and
cause
possible
dam¬
age
to
electrical
compo¬
nents.
