SECTION 1
DESCRIPTION
Should a flame outage occur the control will close the
main gas control valve within 0.8 seconds and attempt to
reignite the pilot.
D. Electric Heaters (Electric Oven Only)
There are six heater elements mounted on the inside of
the rear panel. Each element is connected to a separate
electrical contact which is energized by the temperature
controller.
E. Front Window
The front window is used for viewing items being baked
and provides access to the oven for items which do not
require full bake time, such as sandwiches, cookies,
small items or cheese melting processes.
F. Cooling Fan
A cooling fan is located in the back of the oven. This
cooling fan blows cool air in through the machinery
compartment across the fan motor and conveyor motor
and control cabinet. The air is then exhausted through
the side of the cabinet and also out the back of the oven
compartment. Refer to Figure 1-6.
Another cooling fan is located in the bottom of each
control box. Air is drawn in through the louvers in the rear
of the control box and out through the fan. Refer to Figure
1-4.

III. COMPONENT FUNCTION
A. Conveyor
The conveyor is driven by a variable speed electric motor
operating through a gear reducer (See Figure 1-5). The
motor speed is controlled by a digital control. The stain-
less steel wire belt can travel in either direction and at
variable speeds from 3 minutes to 23 minutes.

B. Fan
The fan is located at the rear of the oven. This fan forces
heated air through the fingers. The fan switch has two
positions and must be "on" for oven warm up and bake
and for the conveyor to run.
C. Gas Burner (Gas Oven Only)
With the heat and blower switches ON the gas burner
heats the air as the air enters the main blowers to
maintain the set temperature. The burner flame is ignited
and monitored by a solid state burner control device.
