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 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.

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
D
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 notified within fifteen days of delivery
and the shipping container is retained for inspection.
The following clearances must be maintained between the oven and any combustible or non-combustible construction.
D

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.
Adequate clearances must be available for servicing.
It is also essential that ventilation air not be obstructed in any way if proper operation is to be assured. Tripping of the blower motor thermal overload protective device is caused by excessive
ambient temperature on the control side of the
oven resulting from insufficient ventilation. Such a
condition must be corrected immediately if permanent damage to the oven is to be avoided.

CONTROL DESCRIPTION
1. POWER ON/OFF - Controls the operation of
the oven. If the power switch is in the OFF position the oven will be turned off.
2. COOL DOWN - When this switch is in the OFF
position, the oven can be used to cook. When
the switch is in the ON position, the oven is not
operating but cooling down for the next bake.
3. OVEN READY LIGHT - When the light is on, the
oven is preheating. When the light goes out, the
oven has reached the desired temperature.
4. THERMOSTAT - Controls the temperature at
which the oven will operate. The range of temperature is from 200_-500_F (93_-260_C).
5. ELECTRIC TIMER - Used to time the length of
the cooking operation. When the preset time
expires, a buzzer will sound.
6. FUSES - Circuit protection for all of the electrical components.

Operation
General Guidelines for Operating Personnel
Always preheat the oven before using by setting
the thermostat to the desired setting. The oven
has reached operating temperature when the
“LIGHT OFF OVEN READY” light goes out.
Follow the Time and Temperature recommendations provided for the product to be prepared in
the oven. Cooking at higher temperatures will not
reduce cooking time, it will produce unsatisfactory
results. Time will vary with the amount of product
loaded, the type of pan and the temperature. Record times and temperatures which provide best
results for future reference.
Five racks are provided with the oven; however, up
to nine may be used. Product or pan height determine the number of racks to be used.
10
Do not place a pan or aluminum foil on the bottom
of the oven. This will obstruct the flow of air and result in uneven baking.
When baking, weigh the product to assure equal
quantities in all pans or uneven results may occur.
For cooking, the selector switch will be placed in
the ON position and the COOL DOWN switch in
the OFF position. When placed in this mode, operation of the blower is automatically controlled by
the action of the doors. Use the ON position of the
COOL DOWN switch when the oven doors are
open to lower the temperature of the oven quickly.

Maintenance
Cleaning and Preventative Maintenance
CLEANING THE OVEN
PREVENTATIVE MAINTENANCE
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.
2. Dry the oven with a clean cloth.
The best preventative maintenance measures are,
the proper installation of the equipment and a program for routinely cleaning the ovens.
On the stainless front or interiors, deposits of
baked on splatter may be removed with any nontoxic industrial stainless steel cleaner. Heat tint
and heavy discoloration may be removed with any
non-toxic commercial oven cleaner.
1. Apply cleaners when the oven is cold. Always
rub with the grain of the metal.
Keep liquid away from the light sockets, temperature probes, heating elements, etc. Avoid spraying the oven’s electrical connections, thermostat
and light bulb receptacles.
The porcelain interior can be cleaned with any
commercial oven cleaner. Be sure caustic cleaning compounds DO NOT come in contact with the
aluminized steel panel directly behind the blower
wheel.
1. Remove the racks and rack supports from the
oven.
2. Soak the parts in a solution of ammonia and
water.
3. Reinstall after cleaning.
12
Annual Maintenance
This oven requires no lubrication, however, the
venting system should be checked annually for
possible deterioration resulting from moisture and
corrosive flue products.
If maintenance or repairs are required, contact
your local Blodgett service company, a factory
representative or the Blodgett Oven company.
WARNING!!
Always disconnect the appliance from the
power supply before servicing or cleaning.
