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 conĆ tinually strips away the layer of cool air surroundĆ ing the product, quickly allowing the heat to peneĆ trate. The result is a high quality product, cooked at a lower temperature in a shorter amount of time.

Blodgett convection ovens represent the latest adĆ vancement in energy efficiency, reliability, and ease of operation. Heat normally lost, is recircuĆ lated within the cooking chamber before being vented from the oven: resulting in substantial reĆ ductions 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:

D Inspect the shipping container for external damĆ

age. Any evidence of damage should be noted on the delivery receipt which must be signed by the driver.

D Uncrate the oven and check for internal damĆ

age. Carriers will accept claims for concealed damage if notified within fifteen days of delivery and the shipping container is retained for inĆ spection.

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 beĆ tween the oven and any combustible or nonĆcomĆ bustible construction.

CTB

D Oven body left side - 0" (0cm) D Oven body back - 0" (0cm)

CTBR

D Oven body right side - 0" (0cm) D Oven body back - 0" (0cm)

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

D Area must be accessible for proper servicing. D Keep the oven area free and clear of all combusĆ

tibles such as paper, cardboard, and flammable liquids and solvents.

D To ensure proper operation, ventilation must not

be obstructed in any way. Tripping of the blower motor thermal overload protective device is caused by excessive ambient temperature on the control side of the oven resulting from insufĆ ficient ventilation. This condition must be corĆ rected immediately to avoid permanent damĆ age to the oven.

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

1. The rating plate is attached to the underside of the oven upper ledge above the control panel.
