SECTION 2 - INSTALLATION

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.

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 supercede the require-

ments and guidelines provided in this manual.

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 - After any conversions, readjustments, or service work on the oven:

 Perform a gas leak test.

 Test for correct air supply, particularly to the burner blower.

 Test for proper combustion and gas supply.

 Check that the ventilation system is in operation.
