Oven Desc iption 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.

and satisfactory performance.
The following clearances must be maintained beĆ
tween the oven and any combustible or nonĆcomĆ
bustible construction.
DOven body right side - 1/2" (1.3 cm)
DOven body left side - 1/2" (1.3 cm)
DOven body back - 1/2" (1.3 cm)
DOven body bottom - 1/2" (1.3 cm)
Adequate clearances must be available for servicĆ
ing.
DKeep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
DDo not place the oven on a curb base or seal to

COOK TIMES AND TEMPERATURES
P eheating the oven
Always preheat the oven before baking or roastĆ
ing. We recommend preheating 50_F (28_C)
above the cook temperature to offset the drop in
temperature when the doors are opened and cold
product is loaded into the oven. et the thermostat
to the cook temperature after the product is
loaded.
NOTE: For frozen product preheat the oven 100_F
(56_C) above the cook temperature.
Cook Tempe atu es
Generally, cook temperatures should be 50_F
(28_C) lower than deck or range oven recipes.
Use this as a starting point and adjust the temperĆ
ature as necessary. If the edges of the product are
done but the center is raw, or if there is color variaĆ
tion, reduce the thermostat setting another
15Ć25_F (10Ć15_C). Continue to reduce the cook
temperature on successive loads until the desired
results are achieved.
NOTE: Cooking at excessive temperatures will
not reduce cook time it will produce unĆ
satisfactory baking and roasting results.
Cook Time
Check the product in about half the time recomĆ
mended for deck or range oven recipes. Record
times and temperatures which provide best reĆ
sults for future reference.
NOTE: Cook time will vary with the amount of
product loaded the type of pan and the
temperature.
OPERATING TIPS
Pans and Racks
Product or pan height determines how many
racks are used. The oven holds up to 10 18" x 26"
(45.7 x 66.0 cm) bun pans.
Load the oven from the bottom, centering the pans
on the rack. Never place a pan or aluminum foil on
the bottom of the oven. This obstructs the flow of
air and results in uneven baking and roasting.
Roasting
To reduce shrinkage when roasting, place meat
directly on the racks. Place a sheet pan oneĆhalf
full of water in the bottom rack position. The water
evaporates, increasing humidity in the oven
chamber. The pan catches grease from the meat,
making oven cleaning easier.
Baking
Weigh the product to ensure equal distribution in
each pan. Varying amounts of product will cause
uneven baking results.
Fans
The fan must be operating for the oven to heat.
Use the Pulse Plus feature to allow light or liquid
product to set in the pan and to avoid rippling toĆ
wards the fan. If your oven is not equipped with
this feature use the following procedure.
1. Preheat the oven 25_F (15_C) above the bakĆ
ing temperature.
2. Load the oven with product. Close the doors.
3. et the thermostat to the baking temperature.
4. Turn the oven off.
5. Allow the product to set for 5Ć7 minutes with
the fan off. The residual heat in the oven sets
the product.
6. Turn the oven on for the remainder of the bake.
Lights
Turn the oven lights off when not viewing the prodĆ
uct. Leaving the lights on for extended periods of
time shortens the bulb life considerably.
