INTRODUCTION

Like any other fine, precision built appliance, the
Master Electric Oven should be given regular care and
maintenance. Periodic inspections by your dealer or a
qualified service agency is recommended.

Rating Plate

When corresponding with the factory or your local
authorized factory service center regarding service
problems or replacement parts, be sure to refer to the

INSTALLATION

Clearances

Combustible and Non-Combustible Wall Clearance:

Side: 1.0” (25mm)

Rear: 6.0” (152mm)

Note: Adequate clearance must be provided for servicing
and proper operation

IMPORTANT Large objects should not be placed in
front of this oven, which would obstruct the airflow
through the front. Objects should not be placed on main
top rear of oven while in use. is could obstruct the
venting system of the units.

Installation of Ovens Equipped with Casters

A. For an appliance equipped with casters, the

installation shall be made with a connector that
complies with the Standard for Connectors for
Movable Appliances, ANSI Z21.69. Adequate
means must be provided to limit the movement of
the appliance without depending on the connector
wiring.

particular unit by the correct model number (including
the prefix and suffix letters and numbers) and the
warranty serial number. e rating plate located behind
the lower front panel (below the oven doors) contains
this information.

Power Failure

In the event of a power failure, no attempt should be
made to operate this oven.

B. e front casters of the unit are equipped with

brakes to limit the movement of the oven without
depending on the connector wiring to limit the
appliance movement.

C. A restraint can be attached to the unit. If the

restraint is disconnected, be sure to reconnect the
restraint after the oven has been returned to its
originally installed position.

Installation of Double Deck Models

A. Position insert in bottom leg opening and tap insert

up into leg until it seats at collar. Attach six inch
(6”) legs to lower oven section. Raise unit or lay on
its left side. Place the front legs on the oven so as to
line up with four (4) attaching bolt holes. Secure
leg to oven frame using (4) 3/8-16 x 3/4 bolts and
washers provided. Repeat at rear of unit.

B. Remove lower front cover of top deck (located

under oven doors). Raise top deck into place and
line up body sides and back of the unit. Fasten the
rear of the units together, with the stacking bracket
using (6) 1/4-20 machine screws, lock washers and
nuts, (provided).

INSTALLATION Continued

C. Install the interconnecting flue parts, carefully

following the instructions contained in the stacking
kit. Pay particular attention to the type of ovens you
are stacking and be sure to follow the corresponding
instructions.

D. Check leveling of unit four (4) ways (using a

common carpenter’s level on the rack inside the
oven).

E. Maintain clearance from combustibles.

CAUTION: Disconnect Both Unites from electrical
Supply Before Servicing.

Electrical Connections

Before attempting the electrical connection, the rating
plate should be checked to ensure that the unit’s electrical
characteristics and the supply electrical characteristics
agree.

Installation of the wiring must be made in accordance
with U.L.  Commercial Electric Cooking Appliance
Standards, Local and/or National Electrical Code,
ANSI/NFPA -, or the Canadian Electrical Code,
CSAC . as applicable.

e service line will enter through the rear of the unit and
is to be connected to the terminal block (see diagram).
e terminal block is accessed by removing the lower
front cover. Removal of the body side is not necessary.

Input voltage and phasing must match the units
voltage and phasing. Wiring diagram is attached to

the main back of each oven. Visually check all electrical
connections. Energize electric service to units. e range
is wired standard for three phase connections. If it is
necessary to change to single phase, please refer to wiring
diagram attached to the rear of the oven. Service and
unit voltage must agree.
