INSTALLATION

WARNING
The oven must be installed on an even (level) non-flammable flooring and any adjacent walls must
be non-flammable. Recommended minimum clearances are specified in the Description section of

this Manual.

WARNING

Do not obstruct the flow of combustion and ventilation air to and from your oven. There must be no

obstructions around or underneath the oven. Constructional changes to the area where the oven is

installed shall not affect the air supply to the oven.

CAUTION

For additional installation information, contact your local Authorized Service Agent.

NOTE

There must be adequate clearance between the oven and combustible construction. Clearance

must also be provided for servicing and for proper operation.

NOTE

An electrical wiring diagram for the oven is located inside the machinery compartment.

NOTE

All aspects of the oven installation, including placement, utility connections, and ventilation requirements,

must conform with any applicable local, national, or international codes. These codes supersede the

requirements and guidelines provided in this manual.

NOTE

In the USA, the oven installation must conform with local codes. Installed ovens must be electrically

grounded in accordance with local codes, or in the absence of local codes,

with the National Electrical Code (NEC), or ANSI/NFPA70.

NOTE - CANADA INSTALLATION

In Canada, the oven installation must conform with local codes. Installed ovens must be electrically

grounded in accordance with local codes, or in the absence of local codes, with the Canadian Electrical Code

CSA C22.2.

NOTE - AUSTRALIA INSTALLATION

In Australia, the oven installation must conform with any requirements of the appropriate statutory authority.

NOTE - CE OVEN INSTALLATION

Four casters are provided to allow the oven to be more easily moved to the installation location. These casters

are intended to simplify pre-installation movement only, and are NOT suitable for use as part of a CE oven

installation. During the installation procedure, the casters MUST be removed, so that the oven can be

supported by the supplied 152mm adjustable legs.

NOTE - GROUNDING INSTRUCTIONS

The oven must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric

shock by providing an escape wirdor electric current. This product is equiped with a cord having a grounding wire

and an appropriate grounding plug. This plug must be plugged into a properly installed outlet in accordance with all

local codes and ordinances.

WARNING: Improper installation of the grounding plug can result in the risk of electric shock. The grounding wire

has insulation with an outer surface that is green with or without yellow stripes.

Implementation of the grounding requirements should be carried out by a qualified electrician or service techni-

cian. Do not modify the appliance plug provided. If the appliance plug does not fit the outlet, the outlet should be

replaced by a qualified electrician.

the oven and any adjacent combustible con­struction. Clearance must also be provided
for servicing and for operation.

CAUTION

It is recommended that the oven be placed under
a ventilation hood for adequate air supply and
ventilation.

CAUTION

Do not obstruct the flow of ventilation air to and
from your oven. Do not obstruct the fan holes in
the rear of the unit.

requirements of the appropriate statutory authority, such
as the National Electrical Code (NEC), ANSI/NFPA70,
(U.S.A.); the Canadian Electrical Code, CSA C22.2; the
Australian Code AG601; or other applicable regulations.

A fused disconnect switch or a main circuit breaker
(customer furnished)
supply line for each oven; it is recommended that this
switch/ circuit breaker have lockout/tagout capability. The
electric supply connection must meet all national and local
electrical code requirements. Copper is the recommended
material for the electrical supply conductors.

MUST be installed in the electric

IV. ELECTRIC SUPPLY

Electrical connection is a fixed conduit connection.
