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 continually strips away
the layer of cool air surrounding the product, quickly allowing the heat to penetrate. The result is a high quality product, cooked at a lower temperature in a shorter
amount of time.
Blodgett convection ovens represent the latest advancement in energy efficiency, reliability, and ease of operation. Heat normally lost, is recirculated within the cooking
chamber before being vented from the oven: resulting in
substantial reductions in energy consumption and enhanced oven performance.

Ventilation
Canopy Type Exhaust Hood
On gas models the installation of a proper ventilation system cannot be over emphasized. This system removes
unwanted vapors and products of combustion from the
operating area.
A mechanically driven, canopy type exhaust hood is the
preferred method of ventilation.
The hood should be sized to completely cover the equipment plus an overhang of at least 6” (15 cm) on all sides
not adjacent to a wall. The distance from the floor to the
lower edge of the hood should not exceed 7’ (2.1m).
This oven may be vented using either:
•
A mechanically driven, canopy type, exhaust hood,
or
•
A direct flue arrangement.
The total makeup and exhaust air requirements for hood
capacity should be approximately 30 CFM (.85 m3) for
each oven section.
U.S. and Canadian installations
Installing the canopy hood draft diverter
Refer to your local ventilation codes. In the absence of
local codes, refer to the National ventilation code titled,
“Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors from Commercial
Cooking Equipment”, NFPA-96-Latest Edition.
Ovens ordered for hood venting are supplied with a draft
diverter. Install the draft diverter as follows:
1. Place the diverter over the flue connector with the
open area facing the front of the oven.
2. Secure both ends with the sheet metal screws provided.
Australia and general export installations

How Cook & Hold Works
With the optional COOK & HOLD feature, meat is roasted
at lower temperatures for longer periods of time. This preserves flavor and tenderness and prevents over drying.
There are three phases in cook and hold roasting.
Primary Cooking - controlled by the COOK & HOLD
TIMER. The meat is cooked at a low temperature
until approximately 2/3 done.
•
Cooking from Stored Heat - when the primary cook
time expires, the oven automatically switches to
HOLD. The product continues to cook from the heat
stored in the oven. Meat must remain in the hold
cycle for a minimum of 1-1/2 to 2 hours before being
served.
•
Oven Temp
Product may be
removed and served.
Meat Temp
Hold - holds the product for several hours before
serving without loss of moisture or tenderness.
Time (hours)
All meat should be completely thawed by refrigeration. Using frozen meat increases the cook time causing shrinkage.

Operation
General Guidelines for Operating Personnel
Cook Times and Temperatures
Operating tips
Preheating the oven
Pans and Racks
Always preheat the oven before baking or roasting. 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. Set
the thermostat to the cook temperature after the product
is loaded.
Product or pan height determines how many racks are
used. The oven holds up to ten 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.
NOTE: For frozen product, preheat the oven 100°F
(56°C) above the cook temperature.
Roasting
Cook Temperatures
To reduce shrinkage when roasting, place meat directly on
the racks. Place a sheet pan one-half 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.
Generally, cook temperatures should be 50°F (28°C) lower than deck or range oven recipes. If the edges of the
product are done but the center is raw, or if there is color
variation, reduce the thermostat setting another 15-25°F
(10-15°C). Continue to reduce the cook temperature on
successive loads until the desired results are achieved.
Baking
Weigh the product to ensure equal distribution in each
pan. Varying amounts of product will cause uneven baking results.
NOTE: Cooking at excessive temperatures will not
reduce cook time, it will produce unsatisfactory
baking and roasting results.
Fans
Cook Time
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 towards the fan. If your
oven is not equipped with this feature use the following
procedure.
Check the product in about half the time recommended
for deck or range oven recipes. Record times and temperatures which provide best results for future reference.
NOTE: Cook time will vary with the amount of product
loaded, the type of pan and the temperature.
1. Preheat the oven 25°F (15°C) above the baking temperature.
2. Load the oven with product. Close the doors.
3. Set the thermostat to the baking temperature.
4. Turn the oven off.
5. Allow the product to set for 5-7 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 product.
Leaving the lights on for extended periods of time shortens the bulb life considerably.
