Hot Surfaces
The appliance may be hot. Do not contact hot surfaces without proper protection. Contact with hot surfaces
can cause serious burns, loss of skin and hair and the use of limbs.
Avoid contact with hot surfaces when loading or unloading the oven. Use appliance mitts to load and unload
product. Contact with hot product can cause you to react suddenly and result in spilling or dropping the
product, which can cause physical harm.
Hot Water, Steam and Spillage Hazards
This appliance produces steam in the process of cooking, which may be released from the oven interior. Steam
is very hot and contact can cause serious burns, loss of skin and hair, loss of the use of limbs and serious injury
to eyes and internal organs. Excessive contact with steam can even result in loss of life. When using the
sandwich door, keep your face and hands clear of the door opening. Also keep your face and hands clear of
the cook chamber entrance and exit openings.
Steam produced by the appliance can cause the floor to become wet. If this happens, wipe or mop up the
water and alert other employees of the hazard. Use caution to avoid slipping when operating this appliance
or when in the area of the appliance.

Sharp Edges and Pinch Hazards
Use caution to avoid contact with sharp edges. Doors, covers, etc. may have edges that can cut or snag skin
and clothes. Use caution when working on, cleaning or servicing the appliance.
Keep hands and fingers out of the path of the sandwich door when closing to avoid pinching.
Strains, Over-Extension, Over-Exertion and Lifting Hazards
Use caution when loading or unloading heavy product from the appliance. Cooked product may be heavy
and result in sprains, strains or injury to back, arms, hands or legs. Do not lift more than you are safely
capable of lifting.

EQUIPMENT DESCRIPTION I
Exterior Dimensions
See Configurations Section.
Construction
The exterior top, front, rear and sides are constructed of stainless steel, as is the sandwich door and oven interior
(including all interior ducting, conveyor belt and entrance/exit shelves).
The exterior underside is constructed of corrosion-resistant aluminized steel.
The sandwich door window is constructed of thick, tempered safety glass.
Performance
Fast-acting gas burner is utilized for rapid run-up and recovery.
Rear-mounted fan thoroughly circulates convection air for rapid cooking and even browning of the food product.
The cook chamber is insulated with high-temp insulation for reduced heat loss and increased energy efficiency.
Controls
Simple, intuitive and easy-to-understand layout.
Large displays for time and temperature.
Belt Time Range: 03m:00s –30m:00s.
Set Point Range: 145-570oF.
Temperature scale can be easily set to either oF or oC.
On shutdown, the last settings used are retained in memory and reappear on the subsequent startup.
Features
Cool-Down Feature. This automatic feature allows the oven to cool slowly to extend the life of the interior electrical
components. On shutdown, if the oven cook chamber temperature exceeds 200oF, the heater fans continue to run
for a period after the heaters have turned off. Once the oven cook chamber temperature has dropped to 200oF, the
fans will automatically stop and the control will turn off. While in cool-down Mode, the word “CooL” will appear in
the Conveyor Speed display.
Change Belt Direction. The direction of the belt can be changed to run from left to right or right to left. A two-
position belt-direction switch with identifying label is located at the backside of the cook chamber. Set the switch
to your desired direction.

Both top ducts match one another and can be reinstalled in any order; there is no need to number them. All
bottom ducts also match one another and can be reinstalled in any order. To further help avoid mistakes during
reinstallation, the oven has been designed so the top ducts fit only in the top position and the bottom ducts fit
only in the bottom position.)
Disassemble horizontal ducts for cleaning. No tools are required. Slide plate from duct body in direction
indicated by arrow. When cleaning, it is important to remove food particles and residue from all perforated holes
of all duct parts.
