Cooking in a convection oven differs from cooking in a
conventional deck or range oven since heated air is con-
stantly recirculated over the product by a fan in an en-
closed chamber. The moving air continually strips away
the layer of cool air surrounding the product, quickly al-
lowing the heat to penetrate. The result is a high qual-
ity product, cooked at a lower temperature in a shorter
amount of time.
Blodgett convection ovens represent the latest advance-
ment in energy efciency, reliability, and ease of opera-
tion. Heat normally lost, is recirculated within the cooking
chamber before being vented from the oven: resulting in
substantial reductions in energy consumption and en-
hanced oven performance.

Delivery and Location
DELIVERY AND INSPECTION
All Blodgett ovens are shipped in containers to prevent
damage. Upon delivery of your new oven:
• Inspect the shipping container for external damage.
Any evidence of damage should be noted on the
delivery receipt which must be signed by the driver.
• Uncrate the oven and check for internal damage.
Carriers will accept claims for concealed damage if
notied within fteen days of delivery and the ship-
ping container is retained for inspection.
The Blodgett Oven Company cannot assume responsibil-
ity for loss or damage suffered in transit. The carrier as-
sumed full responsibility for delivery in good order when
the shipment was accepted. We are, however, prepared
to assist you if ling 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-combustible con-
struction.
• Oven body right side - 0” (0 cm)
• Oven body left side - 0” (0 cm)
• Oven body back - 0” (0 cm)
• Oven body bottom - 4-1/2” (11.4 cm)
Adequate clearances must be available for servicing.
• Keep the oven area free and clear of all combus-
tibles such as paper, cardboard, and ammable
liquids and solvents.
• Do not place the oven on a curb base or seal to
a wall. This will restrict the ow 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 specications are
compatible with the electrical services supplied for the
oven.
1. The rating plate is attached to the body back.
