Inadequate ventilation, or failure to ensure an adequate supply of fresh air will result in a high ambient temperature at the rear of the appliance. An excessive ambient temperature can cause the thermaloverload protection device on the blower motor to trip resulting in severe damage to the blower motor.

C A U T I O N

TO PREVENT PERSONAL INJURY,

USE CAUTION WHEN MOVING OR

LEVELING THIS APPLIANCE.

I N S T A L L A T I O N R E Q U I R E M E N T S

The oven must be mounted on the factory equipped oven legs or on an optional oven stand. Installation on a solid or concrete base that in any way restricts air flow may void the warranty.

All clearances for a proper ventilation air supply must be maintained to minimize fire hazard. Do not locate the oven immediately adjacent to any other heat-generating appliance.

A number of adjustments are associated with initial installation and start-up. Adjustments must be conducted by a qualified service technician. Installation and start-up adjustments are the responsibility of the dealer or user. These adjustments include but are not limited to thermostat calibration, door adjustment, leveling, and gas pressure verification. The Platinum series oven burners are factory-adjusted with fixed air openings and require no field adjustment.

LEVELING

he oven should

T be leveled before the gas supply is connected. Level the oven from side-to-side and front-to-back with the use of a spirit level. For ovens installed on a mobile stand, it is important that the floor surface be level due to the probability of frequent oven repositioning.

We recommend checking the level of the oven periodically to make certain the floor has not shifted nor the oven moved.

NOT E: Failure to properly level this oven can

cause improper function as a result of erratic burner combustion and will result in the uneven baking of products consisting of semi-liquid batter.

GAS SUPPLY & INSTALLATION

D A N G E R

Installation, air adjustment and/or s

ervice work must be in accordance with all local codes and must be performed by a certified service technician qualified to work on gas appliances.

GAS REQUIREMENTS

The gas inlet is located at the back of the oven. Code requires the installation of a manual gas shutoff valve to be installed in the gas line ahead of the oven. This oven is also equipped with fixed burner orifices determined by the elevation specified as the initial installation location.

The oven is furnished with a regulator integral to the operation of the gas solenoid valve and may not require an additional external regulator. To ensure safe and proper operation, the gas pressure regulator installed in the oven is required for use with both natural gas and propane. If the connected pressure exceeds 14.0" W.C. (3.48 kPa), a step-down regulator is required. A step-down regulator is not the responsibility of the manufacturer.

Use an approved pipe sealant at all connections. Do not use Teflon® tape. Gas supply connections and pipe joint compound must be resistant to the action of propane gases. Pipes must be clean, free of obstructions and pipe joint compound.

GAS CONNECTION

In the U.S.A. , installation must c onform to loc al codes o r, in the absence of local codes, wit h the current edition of the Nat ional Fuel Gas Code, NFPA-54 and ANSI Z223.1-1980 (la test edition). In Canada, installation must be in accordance with local codes, CAN /CGA-B149. 1, Installa tion for N a tural Gas Bur n ing Applia nces and E q uipment (latest edition) or C AN/CGA-B14 9.2 Install a tion for

The oven must be supplied with a flexible connector that complies with The Standard for Connectors for Movable Gas Appliances, ANSI Z21.69, CGA 6.16 and addenda Z21.69a (latest editions). A quick disconnect device must be installed to comply with The Standard for Quick Disconnect Devices for Use with Gas Fuel, ANSI Z21.41 and CAN1-6.9 (latest editions). A flexible connector is not supplied by the factory.

Adequate means must be provided to limit the movement of the appliance. Limitation of movement must be made without depending on the connector, the quick disconnect device, nor the associated piping designed to limit oven movement. Mounting holes for a restraining device are located on the lower back flange of the oven chassis.

To avoid electrical shock, this appliance MUST be adequately grounded in accordance with local electrical codes or, in the absence of local codes, with the current edition of the National Electrical Code ANSI/NFPA No. 70. In Canada, all electrical connections are to be made in according with CSA C22.1, Canadian Electrical Code Part 1 or local codes.

E L E C T R I C A L C O N N E C T I O N

This appliance is equipped with a three-prong grounding plug. For your protection against shock hazard this appliance should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.

Plug the unit into a properly grounded receptacle ONLY, positioning the unit so that the plug is easily accessible in case of an emergency. Arcing will occur when connecting or disconnecting the unit unless all controls are in the “OFF” position.

Proper receptacle or outlet configuration or permanent wiring for this unit must be installed by a licensed electrician in accordance with applicable local electrical codes.

AILURE TO VENT THIS APPLIANCE PROPERLY MAY BE HAZARDOUS TO THE HEALTH OF THE OPERATOR. Equipment damage, operational problems and unsatisfactory baking performance may also be the consequence of improper venting. Any damage sustained by a failure to properly vent this oven are not covered under warranty.

D A N G E R

Installation, air adjustment and/or service work must be in accordance with all local codes and must be performed by a certified service technician qualified to work on gas appliances.

VENTILATION H O O D S

Proper venting along with a sufficient quantity of make-up air is essential for proper oven operation. A mechanically driven, canopy exhaust hood is the preferred method of ventilation and must conform to local codes along with the current version of NFPA-96 Vapor Removal from Cooking Equipment (latest edition). The oven hood must extend 6" (152mm) beyond all sides of the oven. The distance from the floor to the bottom edge of the hood should be between 6'6" (1981mm) and 7' (2134mm).

I N S TA L L A T I O N

DIRECT VENTING

Whe n n ecessary, direct ve nting can be used in situations where space is limited or to help offset the high cost of ventilat ion hoods.

Direct venting should be installed in compliance with local codes by a certified professional. In the absence of local codes, refer to National Fuel Code NFPA 54, ANSI Z223.1 (latest revision).

A ventilation hood that supplies make-up air down the back vertical wall should be avoided since air currents can interfere with the oven flue exits. If such installation is unavoidable, an additional draft hood, specifically designed to deflect downdrafts, must be installed.

Ventilating hoods and exhaust systems shall be permitted to be used to vent appliances installed in commercial applications.

Where automatically operated appliances are vented through a ventilating hood or exhaust system equipped with a damper or with a power means of exhaust, provisions shall be made to allow the flow of gas to the main burners only when the damper is open to a position to properly vent the appliance and whe n the power mean s of exhaust is in ope ration.
