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.
D Oven body right side - 1/2" (1.3 cm)
D Oven body left side - 1/2" (1.3 cm)
D Oven body back - 1/2" (1.3 cm)
D Oven body bottom - 1/2" (1.3 cm)
Adequate clearances must be available for servicĆ
ing.
D Keep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
D Do not place the oven on a curb base or seal to
a wall. This will restrict the flow of air and prevent
proper ventilation resulting in damage 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 under ledge
above the door.
