Introduction

Oven Description and Specifications

Cooking in a convection oven differs from cooking in a conventional deck or range oven since heated air is constantly recirculated over the product by a fan in an enclosed chamber. The moving air continually strips away the layer of cool air surrounding the product, quickly allowing the heat to penetrate. The result is a high quality product, cooked at a lower temperature in a shorter amount of time.

Blodgett convection ovens represent the latest advancement in energy efficiency, reliability, and ease of operation. Heat normally lost, is recirculated within the cooking chamber before being vented from the oven: resulting in substantial reductions in energy consumption and enhanced oven performance.

Delivery and Location

DELIVERY AND INSPECTION

All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven:

DInspect the shipping container for external damage. Any evidence of damage should be noted on the delivery receipt which must be signed by the driver.

DUncrate the oven and check for internal damage. Carriers will accept claims for concealed damage if notified within fifteen days of delivery and the shipping container is retained for inspection.

The Blodgett Oven Company cannot assume responsibility for loss or damage suffered in transit. The carrier assumed full responsibility for delivery in good order when the shipment was accepted. We are, however, prepared to assist you if filing a claim is necessary.

OVEN LOCATION

The well planned and proper placement of your oven will result in long term operator convenience and satisfactory performance.

The following clearances must be maintained between the oven and any combustible or non-com-bustible construction.

DFG100

D Oven body right side---2” (5cm)D Oven body left side---2” (5cm)D Oven body back---0” (0cm)

D Oven body bottom---6” (15cm)

DFG200

D Oven body right side---6” (15cm)D Oven body left side---6” 6” (15cm)D Oven body back---6” (15cm)

D Oven body bottom---6” (15cm)

The following clearances must be available for servicing.

D

Oven body sides ---

12” (30cm)

D

Oven body back ---

12” (30cm)

NOTE: On gas models, routine servicing can usually be accomplished within the limited movement provided by the gas hose restraint. If the oven needs to be moved further from the wall, the gas must first be turned off and disconnected from the oven before removing the restraint. Reconnect the restraint after the oven has been returned to its normal position.

It is essential that an adequate air supply to the oven be maintained to provide a sufficient flow of combustion and ventilation air.

D Place the oven in an area that is free of drafts.

DKeep the oven area free and clear of all combustibles such as paper, cardboard, and flammable liquids and solvents.

DNSF requires 6” of clearance on the bottom and sides of the unit for cleaning. Do not place the oven on a curb base or seal to a wall.

DThe location must provide adequate clearance for the air opening into the combustion chamber.

Before making any utility connections to this oven, check the rating plate to be sure the oven specifications are compatible with the gas and electrical services supplied for the oven.

1.Remove the combustion compartment cover. The rating plate is attached to the frame on the left side of the combustion compartment.
