Installation & Operation Manual
1. DESCRIPTION
The XLT TS/TS2 series of ovens consist of six models; the 1832 TS/TS2, the 2440 TS/TS2,
3240 TS/TS2, the 3255 TS/TS2, the 3270 TS/TS2, and the 3870 TS/TS2. The first two
digits of the model number represent the conveyor width, and the second two digits indicate
the bake chamber length. Ovens with a longer bake chamber length have a higher cooking
capacity. The TS/TS2 designation represents the fact that the ovens are triple stackable. The
ovens may be used in a single oven stack, a double oven stack, or a triple oven stack. A
single stack or double stack oven can be upgraded by adding another oven deck or two up to
the maximum of three. All ovens are gas fired and are available in Natural gas or LP
(Propane) gas models. (Electric ovens are also available). The 3270 TS/TS2 and
3870 TS/TS2 models have two burners, one right hand and one left hand. They also have
two control boxes, again one right and one left. The other models have only a single right
hand burner with a single right hand control box. All models can have the optional split belt
conveyor.
Figure 1: Examples of Single Double and Triple Stack Ovens
Food product is placed on the stainless steel wire conveyor belt on one side of the oven. The
conveyor then transports the food through the bake chamber at a user controlled speed. This
provides repeatable and uniform food cooking. The conveyors can be easily configured to
move either left to right or right to left. A large center sandwich door allows the
introduction or removal of food items for cooking at shorter times. Temperatures up to
550°F inside the oven are achieved by means of a user adjustable digital control.
An easily removable front panel allows the full cleaning of the oven interior. All exposed
oven surfaces both exterior and interior are constructed of stainless steel. The conveyor is a
one piece design and is removed from the right side of the oven. No tools are required for
disassembly and cleaning of the conveyor or oven interior. The oven itself is mounted on
lockable swivel casters for easy moving and maintenance. Examples of single, double and
triple stack ovens are shown in Figure 1. An oven drawing with nomenclature is shown in
Figure 2.

2. OPERATOR CONTROLS
The operator controls for the ovens are located on the
Control Box which is on the right side of the oven. The
fan, burner, and conveyor switches with the operating
instructions are shown in Figure 5. Also nearby are the
temperature control, the conveyor control, and the fuse
bank, (see Figure 6).
The 3270 TS/TS2 and 3870 TS/TS2 ovens have an
additional Control Box on the left side, (see Figure 7).
The duplicate oven Switch Panels on these models
allow the oven to be operated from either side of the
oven.

Figure 6: Right Hand Side Control Panel (All Models)
All XLT ovens have a right hand side Control Panel. The fuses are located on the Control
Panels and are labeled for their function and replacement part number. It is very important to
use only the fuses listed. Using larger or smaller fuses than what is labeled on the oven can
cause serious damage to the operator and/or the oven and will also void any and all
warranties. See Figure 6.
A conveyor control is located at the top of the panel, and a temperature control is located
mid panel. A cooling fan with washable filter is near the bottom of the panel. The filter is
held in place by a snap on fan guard.

Figure 7: Left Hand Side Control Panel (3270-TS/TS2 and 3870-TS/TS2)
3270 TS/TS2 and 3870 TS/TS2 ovens also have a left hand side Control Panel. This panel
houses the fuses for the equipment inside the left hand control box. A second temperature
control is also used for controlling the burner on the left half of the oven. This allows for two
different temperature zones within these ovens for cooking flexibility, with a maximum
delta of 50º F. Another cooling fan is near the bottom of the panel. See Figure 7.

Figure 8: Optional Right Hand Control Panel (Split Belt Conveyor)
A popular option on the XLT oven is the split conveyor belt. This allows for 2 different
conveyor speeds through the oven. Figure 8 shows the right hand control panel when the
split belt option is present. The difference is that a second conveyor control is also present.
