4. LOCATION AND MINIMUM CLEARANCES

Adequate air space must be provided for the proper venting of the rear exhaust air and provision made for
venting of cooking vapors. The Conveyor Oven must be installed in a well-ventilated area.
NOTE: Attached rear rubber bumpers must not be removed and can contact a rear wall if present.

Conveyor Ovens can be installed with "ZERO" clearances (back and sides) from combustible and non­combustible materials. (Rear rubber bumpers are the “Zero” clearance points on the back of the unit.) See
rating plate attached to the control box door panel.

The Conveyor Oven is intended for countertop mounting if mounted on the 4" legs provided. The Oven is
NOT approved for mounting on any floor. Keep the area around your conveyor oven free and clear of all
combustible materials.

5. INSTALLATION

In MASSACHUSETTS: All gas products must be installed by a “Massachusetts” licensed plumber or gas

fitter. Ventilation hoods must be installed in accordance with NFPA-96, current edition, with interlocks as
described in that standard.

Place the conveyor oven and parts as close to the area of final installation before uncrating. Your conveyor
oven is packed sitting on its bottom. Leave it this way until unpacked. The pallet may be left under the
conveyor oven for convenience in further handling. Unpack carefully to avoid damage to the unit. If
concealed damage is discovered, follow the instructions detailed in Section 1 above.

DO NOT LIFT EXCESSIVE WEIGHT

A. Legs are shipped unattached. Make sure each leg is attached and tightened before placing the

conveyor oven in place. Each leg is adjustable to accommodate variations in the mounting surface.

B. Using sufficient help (2 or more people), lift the conveyor oven upward and place on the countertop

surface. Lift the conveyor oven by gripping the bottom of the unit. THE FOLLOWING ITEMS ARE
NOT TO BE USED AS LIFTING "HANDLES": Side-mounted control boxes (2), front door, the
conveyor belt assembly, the rear fan housing assembly.

C. THE CONVEYOR BELT ASSEMBLY IS MOUNTED BACKWARDS FOR SHIPPING. THE

CONVEYOR BELT ASSEMBLY MUST BE REMOVED AND REVERSED PRIOR TO OPERATION.
See Section 9a, b for further instructions.

D. Position the conveyor oven in its final location, maintaining the minimum clearances specified in

Section 4 above.

E. Remove all loose parts and packages from the interior of the conveyor oven. The conveyor oven

6. STACKING

Your conveyor oven(s) can be
stacked up to (3) high. Each
unit is built exactly the same,
so it does not matter in which
order they are stacked. For
stacking of (2) units, remove
the legs from the second
(upper) unit prior to mounting
on top of the bottom unit. For
stacking of (3) units, it is
preferable to use a "stacking
kit", which allows all conveyor
ovens to be supported by an
external framework, such as a
table, with each conveyor
oven having all legs removed.

"CAUTION: If you use a multiple stack
assembly, remember that each oven has
its own power disconnect. Make sure
ALL main switches are OFF before any
cleaning or maintenance is performed.”

1. Remove two bottom screws from the top oven rear panel.

2. Remove two top screws from the bottom oven rear panel.

Plenum Fingers

The conveyor oven contains (4) plenum fingers that direct air onto the product surface while
cooking. This3-piece assembly comes apartforcleaning, as shown below:

AIR PLENUM FINGER ASSEMBLY

Outer Perforated

Panel

(Stainless Steel)

Although symmetrical
in design, inner panel

must have flanges

facing up as shown

Main Panel

(Aluminized Steel)

Inner Perforated

Screen

(Stainless Steel)

The Outer Perforated panel is locked into place through a friction fit to the Main panel. This method
of fastening also captures the Inner panel, holding it in place. The Outer panel slides off the Main
panel, exposing the perforated Inner panel. The Inner panel is symmetrical in design, and may be
placed in either direction, as long as the outer flanges are pointing as shown in the figure

The Inner and Outer panels are made of stainless steel, and therefore may be exposed to strong
cleaners to remove baked-on grease, etc. Overnight soaking in a hot cleaning solution will improve
thecleaningprocess.

The Main panel is made of aluminized steel like the main cook chamber, and thus requires the same
level of care to retain its integrity. Follow the same precautions as mentioned above for the main
cookchamber.

17. CONVEYOR INSTALLATION

Installingtheconveyorbeltassemblyis done in exact reverse order to its removal.TheMOSTIMPORTANT
POINT is to properly align the drive shaft pin with the gearmotor coupling. If the drive shaft pin must be
wedged into place for installation, the coupling location needs to be adjusted. See Section 6a for this
procedure.

18. CONVEYOR BELT SPEED CALIBRATION

The conveyor belt requires calibration to properly align the speed control knob on the Gas Control Box.
Calibration is done by timing the belt as it passes between two timing marks located on the conveyor frame.
Thismethodwillwork regardless of belttraveldirection.Follow the instructionsbelow.

A. Remove the adjustment knob of the conveyor belt speed control (see page 10) using a small,

standardscrewdriverto loosen the setscrew.

B. Locate the two timing marks as shown. The marks are 7 inches apart. If the timing marks are NOT

present,useablack marking pen tomarktheframe in the same manner.
C. Thesedistancesrepresent exactly ¼ofthelengthof the cook chamber:¼x28 cook chamber =7.
D. Withthis1:4ratio, it is possible tocalibratethe belt speed. For example:

1. For a cook time of 1 minute, the time required to pass between timing marks would be: 60
seconds / 4 = 15 seconds. If the belt passes from one mark to the next in 15 seconds, this is
exactlythesameas a 1-minute cooktime.

2. For a cook time of 6 minutes, the required time to pass between timing marks would be: 6
minutes x 60 seconds / 4. This equals 360 seconds / 4 = 90 seconds between marks. The
belt needs to take 90 seconds (1-1/2 minutes) to move from one mark to the next to equal a

6-minutecooktime.

16

E. Using a black marking pen, mark any belt link near the outer edge. Using a stopwatch, check the

time it takes for this link to move between the timing marks. Repeat this procedure several times
until the distance is traveled in 90 seconds (recommended calibration interval), which equals a 6­minute cook time.

F. Now that the belt is moving at this calibrated speed, CAREFULLY re-mount the adjustment knob

onto the belt conveyor speed control shaft, and tighten the setscrew so that the KNOB indicating
mark is pointing at the number “6”on the surrounding label.

G. The conveyor belt is now calibrated forALL ranges as indicated on the label. The label numbers are

COOK TIME in MINUTES. Simply pointthe knob indicating line to the desired cook time.

NOTE:

The label COOK TIME marks are close approximates, and may vary slightly from actual

timing results using the method described.

1. Locate the two temperature controls
mounted with power control box on the
hinged door, near the cooling fan. Verify
that ALL connections and connectors are
properly fastened and tight. Power
should be connected to terminals labeled
120 & VAC COM.

2. Locate the two wires from each of the
temperature sensors (top left terminals
labeled PROBE). These have braided
insulation. Verify their integrity.

4. If resistance reads value within range of
chart, sensor is good, control needs further
investigation. Re-connect sensor wire
leads. (See diagram at back of manual for
proper identification of controls).

NOTE: temperature sensor lead wires
are NOT polarity sensitive, since sensor
is an RTD-type.

5. If both sensors are good, swap sensor
leads between controls. Turn temperature
knobs ON & OFF. Whichever light works

AGENT.

4. At burner access holes, verify the
burner assembly is grounded (green
wire, ring terminal to burner support
bracket).

5. At same burner access holes, verify 3-
wire harness is properly connected.

6. At Gas Control Box, verify each 3-wire
burner harness is properly connected to
12-pole terminal block.

7. At 12-pole terminal block, verify all
wires are tight by exerting small pull on
each wire.

8. If one burner lights, determine which
ignition module is operating properly, and

7-wire

swap ignition harnesses between
modules . Check if burner ignition
problem follows ignition module.

9. To verify if gas valve is operating
correctly, swap ignition module wires
from one valve to another, observing if
burner ignition problem changes burners.

10. By steps 8 & 9, it should be possible
to determine if ignition module is good.
Replace any module that is defective.

11. Verify that temperature control inputs
are correct & tight at 12-pole terminal
block.

12. Verify that vacuum switch wires are
in tact and that plastic hoses are
connected.

13. Verify that transformers are wired
correctly and operating properly.

14. If either gas valve is defective,
replace.

15. If both ignition modules are good,
and any ignitor fails to glow at call for
heat, re-check wiring at 12-pole terminal
block before replacing ignitor.

16. If burner ignites, but flame goes out
in a few seconds, re-check wiring at 12-
pole terminal block before replacing
flame sensor.

20. TEMPERATURE CONTROL CONVERSION CHART - OHMS TO DEGREES

The temperature sensor (probe) that is supplied with this conveyor oven is an RTD type, which yields an
output based on Ohms of resistance. This particular RTD device has a linear resistance curve that
produces a very predictable amount of resistance that can be converted to degrees Fahrenheit. This
particular device produces a resistance increase of 2 Ohms per every 1 degree F. The baseline value is
approx. 1000 ohms at 32 °F (0°C).
