4.2.1.1. Single Oven Placement Requirements

Place oven on a solid foundation such as a bench top, an optional cabinet base, or directly on
the floor.

Allow at least two inches clearance at the rear of the oven to provide proper ventilation. The
oven may be placed next to another cabinet or next to another oven, with three-quarters of an
inch clearance. The doors will still open.

Plumb and level the oven to assure proper heat distribution and operation of all mechanical
components.

Do not expose oven to excessive vibration and affix all electrical cabinets.

If placing the oven in an area where excessive particulate matter exists (such as a construction
site or a coal processing center), periodically clean all its electrical compartments. Keep the
power supply within the specifications provided by Despatch, and use a line conditioner for a
facility with an unstable power supply.
4.2.1.2. Multiple Oven Placement Requirement

Stack up to two ovens vertically, with or without the optional framework supplied by
Despatch.

Use the holes in the rear oven feet to bolt the ovens together by removing the hole plugs in
the top of the oven beneath.
4.2.2. Exhaust Connections
The RAD1-42-2E oven exhaust port is located on the rear of the oven. The exhaust port is
covered by a hat bracket. For safety reasons, do not remove the hat bracket. Install an exhaust
stack from the port to the outside of the building. Table 1 lists the requirements for the exhaust
stack for the RAD1-42-2E oven.

All stacks must comply with state and local building codes
to insure that surrounding combustible surfaces are below
71°C (160°F).

Use a minimum area greater than the area of the exhaust stack when using an exhaust stack.
Design the exhaust stack to limit the amount of restrictions to ensure proper airflow. Over-all
airflow will be reduced if more than two elbows are used in the exhaust stack.
