Installation cont’d
Ventilation and Clearances
Standard minimum clearance from combustible construction is as follows.
4” from side
4” from back
6” from floor
These ovens may be set directly, without legs, on a curbed base or
non-
combustible
floor.
If the oven is set without legs on a
non-combustible
floor or a curbed base,
maintain a 4-inch back clearance.
If the oven is set directly against a
non-combustible
back wall, maintain a 6-
inch clearance to the floor.
Do not
install the oven closer than 4 inches from another oven on the right
hand side (control panel side).
Do not
install the oven closer than 12 inches from an uncontrolled heat source
(char broiler etc.) on the right side.
Keep the appliance area free and clear of combustible material and do not
obstruct the flow of combustion or ventilation air.
The installation of any components such as a vent hood, grease extractors,
and/or fire extinguisher systems, must conform to the there applicable nationally
recognized installation standards.
Electrical Connection
The electrical connection must be made in accordance with local codes or in
the absence of local codes with
NFPA No. 70
latest edition (in Canada use
:
CSA STD. C22.1
).
The electrical service entrance is provided by a 1 1/4-inch knockout in the
bottom right front corner of each oven, or at the oven back directly behind the
control compartment. Grounding lugs are provided at both the front and rear
service entrances.
The 208/240-volt oven is a dual voltage oven and is shipped from the factory
as 208 volt. The oven must be field converted to operate on a 240-volt power
supply.
To convert the oven to 240 volt, remove the jumper wire located on a terminal
strip located inside the lower portion to the control compartment.
With 380, 400, & 480-volt installations check to be sure that the motor rotates
in a clockwise direction as viewed from the front of the oven.
To reverse the motor rotation, switch any two incoming power supply leads
and recheck the rotation.
Supply wire size must be large enough to carry the amperage load for the
number of ovens being installed. Wire size information can be found on the
oven DATA PLATE. Oven power requirements and service connections can be
obtained from the wiring diagram located in the wiring diagram section of this
manual.
This oven can be installed on both single and three phase supplies and is
shipped
from the factory for three phase.
To phase the oven to match the power supply, follow the charts on page 10 for
proper wire size and grouping.
