Introduction
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 con-
tinually strips away the layer of cool air surround-
ing the product, quickly allowing the heat to pene-
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 ad-
vancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recircu-
lated within the cooking chamber before being
vented from the oven: resulting in substantial re-
ductions in energy consumption and enhanced
oven performance.

Delivery and Location
DELIVERY AND INSPECTION
OVEN LOCATION
All Blodgett ovens are shipped in containers to
prevent damage. Upon delivery of your new oven:
The well planned and proper placement of your
oven will result in long term operator convenience
and satisfactory performance.
D
Inspect the shipping container for external dam-
age. Any evidence of damage should be noted
on the delivery receipt which must be signed by
the driver.
The following clearances must be maintained be-
tween the oven and any combustible or non-com-
bustible construction.
D
Uncrate the oven and check for internal dam-
age. Carriers will accept claims for concealed
damage if notified within fifteen days of delivery
and the shipping container is retained for in-
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.
The following clearances must be available for ser-
vicing.
D
Oven body sides --- 12” (30 cm)

D
Keep the oven area free and clear of all combus-
tibles such as paper, cardboard, and flammable
liquids and solvents.
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 specifi-
cations are compatible with the electrical services
supplied for the oven.
1. The rating plate is attached under ledge
above the door.

General Guidelines for Operating Personnel
COOK TIMES AND TEMPERATURES
Preheating the oven
OPERATING TIPS
Pans and Racks
Always preheat the oven before baking or roast-
ing. We recommend preheating 50_F (10_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 thepans
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 (38_C) above the cook tempera-
ture.
Roasting
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.
Cook Temperatures
Generally, cook temperatures should be 50_F
(10_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 ther-
mostat setting another 15-25_F (10-15_C). Con-
tinue to reduce the cook temperature on succes-
sive 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 un-
satisfactory baking and roasting results.
Fans
The fan must be operating for the oven to heat. To
avoid rippling of batter product use the following
procedure.
Cook Time
Check the product in about half the time recom-
mended for deck or range oven recipes. Record
times and temperatures which provide best re-
sults for future reference.
1. Preheat the oven 25_F (15_C) above the bak-
ing 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.
NOTE: Cook time will vary with the amount of
product loaded, the type of pan and the
temperature.
6. Turn the oven on for the remainder of thebake.

Maintenance
Cleaning and Preventative Maintenance
CLEANING THE OVEN
PREVENTATIVE MAINTENANCE
Painted and stainless steel ovens may be kept
clean and in good condition with a light oil.
1. Saturate a cloth, and wipe the oven when it is
cold.
The best preventative maintenance measures are,
the proper installation of the equipment and a pro-
gram for routinely cleaning the ovens.
Annual Maintenance
2. Dry the oven with a clean cloth.
This oven requires no lubrication, however, the
venting system should be checked annually for
possible deterioration resulting from moisture and
corrosive flue products.
On the stainless front or interiors, deposits of
baked on splatter may be removed with any non-
toxic industrial stainless steel cleaner. Heat tint
and heavy discoloration may be removed with any
non-toxic commercial oven cleaner.
If maintenance or repairs are required, contact
your local Blodgett service company, a factory
representative or the Blodgett Oven company.
1. Apply cleaners when the oven is cold. Always
rub with the grain of the metal.
The porcelain interior can be cleaned with any
commercial oven cleaner. Be sure caustic clean-
ing compounds DO NOT come in contact with the
blower wheel and the aluminized steel panel di-
rectly behind it.
WARNING!!
Always disconnect the appliance from the
power supply before servicing or clean-
ing.
1. Remove the racks, rack supports and blower
wheel cover from the oven.
2. Soak the parts in a solution of ammonia and
water.
3. Reinstall after cleaning.
