SECTION 2 – INSTALLATION

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

• Perform a gas leak test. • Test for proper combustion and gas supply.

• Test for correct air supply, particularly to the • Check that the ventilation system is in operation. burner blower.

WARNING - Keep the appliance area free and clear of combustibles.

WARNING – The oven must be installed on an even (level) non-ammable ooring and any adjacent walls must be non-ammable. Recommended minimum clearances are specied in the Description

section of this manual.

WARNING – Do not obstruct the ow 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: To reduce the risk of re, the appliance is to be mounted on oors of noncombustible construction

with noncombustible ooring and surface nish and with no combustible material against the underside thereof, or on noncombustible slabs or arches having no combustible material against the underside thereof, such construction shall in all cases extend not less than 12 inches (304mm) beyond the equipment on all sides.

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 require-

ments, 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 to local codes. In the absence of local codes, gas oven installations must conform with the National Fuel Gas Code, ANSI Z223.1. Gas and electric ovens, when installed, 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: In Canada, the oven installation must conform with local codes. In the absence of local codes, gas oven installations must conform with the Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Gas Installation Code, CAN/CGA-B149.2, as applicable. Gas and electric ovens, when installed, 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: In Australia, the oven installation must conform with local codes. In the absence of local codes, gas oven installations must conform with the requirements of AS5601/AG601, Gas, Electricity, and any other relevant statutory regulations.

III. VENTILATION SYSTEM

IMPORTANT

Where national or local codes re-

pression equipment or other

supplementary equipment, DO NOT

mount the

equipment directly to the oven.

B. Recommendations

NOTE THAT THE HOOD DIMENSIONS SHOWN IN FIGURE 2-5 ARE RECOMMENDATIONS ONLY. LOCAL, NATIONAL AND INTERNATIONAL CODES MUST BE FOLLOWED WHEN INSTALLING THE VENTILATION SYSTEM. ANY APPLICABLE CODES

SUPERSEDE THE RECOMMENDATIONS SHOWN IN THIS MANUAL. IN AUSTRALIA COMPLIANCE TO REGULATIONS AS5601/AG601 IS MANDATORY.

MOUNTING SUCH EQUIPMENT ON

THE OVEN MAY:

• VOID AGENCY CERTIFICATIONS

• RESTRICT SERVICE ACCESS

• LEAD TO INCREASED SERVICE EXPENSES FOR THE OWNER

A. Requirements

CAUTION: Gas oven installations REQUIRE a mechani-

cally driven ventilation system with electrical exhaust air sensing control.

A mechanically driven ventilation system is STRONGLY RECOMMENDED for electric oven installations.

PROPER VENTILATION OF THE OVEN IS THE RESPONSIBILITY OF THE OWNER.

Figure 2-5. Ventilation System

6″ (152mm)

minimum

(Typical - both

ends of oven)

2″ (51mm)

To avoid a negative pressure condition in the kitchen area, return air must be brought back to replenish the air that was exhausted. A negative pressure in the kitchen can cause heat- related problems to the oven components as if there were no ventilation at all. The best method of supplying return air is through the heating, ventilation and air conditioning (HVAC) system. Through the HVAC system, the air can be temperature-controlled for summer and winter. Return air can also be brought in directly from outside the building, but detrimental effects can result from extreme seasonal hot and cold temperatures from the outdoors.

NOTE: Return air from the mechanically driven system

must not blow at the opening of the baking chamber. Poor oven baking performance will result.

C. Other ventilation concerns

• Special locations, conditions, or problems may require the services of a ventilation engineer or specialist.

• Inadequate ventilation can inhibit oven performance.

• It is recommended that the ventilation system and duct
