Introduction

Oven De cription and Specification
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.

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
DOven body left side - 0" (0cm)
DOven body back - 0" (0cm)
CTBR
DOven body right side - 0" (0cm)
DOven 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.
DArea must be accessible for proper servicing.
DKeep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
DTo 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.
