Oven Description and Specications
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 qual-
ity product, cooked at a lower temperature in a shorter amount of time.
Blodgett convection ovens represent the latest advance­ment in energy efciency, 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
All Blodgett ovens are shipped in containers to prevent damage. Upon delivery of your new oven:
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 notied within fteen days of delivery and the ship­ping container is retained for inspection.
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 ling a claim is necessary.
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 between the oven and any combustible or non-combustible con­struction.
Oven body right side - 1/2” (1.3 cm)
Oven body left side - 1/2” (1.3 cm)
Oven body back - 1/2” (1.3 cm)
Oven body bottom - 1/2” (1.3 cm)
Adequate clearances must be available for servicing.
Keep the oven area free and clear of all combus- tibles such as paper, cardboard, and ammable liquids and solvents.
Do not place the oven on a curb base or seal to a wall. This will restrict the ow 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 specications are
compatible with the electrical services supplied for the oven.
1. Pull out control panel. The rating plate attached to the inside of the control compartment.

Operation
General Guidelines for Operating Personnel
COOK TIMES AND TEMPERATURES
Preheating the oven
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.
NOTE: For frozen product, preheat the oven 100°F
(56°C) above the cook temperature.
Cook Temperatures
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.
NOTE: Cooking at excessive temperatures will not
reduce cook time, it will produce unsatisfactory baking and roasting results.
Cook Time
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.
OPERATING TIPS
Pans and Racks
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 ow 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 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.
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 towards 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 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.

Maintenance
Cleaning and Preventative Maintenance
CLEANING THE OVEN
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.
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.
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.
PREVENTATIVE MAINTENANCE
The best preventative maintenance measures are, the
proper installation of the equipment and a program for
routinely cleaning the ovens.
Annual Maintenance
This oven requires no lubrication, however, the venting
system should be checked annually for possible deterio-
ration resulting from moisture and corrosive ue products.
If maintenance or repairs are required, contact your local
Blodgett service company, a factory representative or the Blodgett Oven company.
WARNING!!
Disconnect the oven from the power supply before servicing. It is not necessary to unplug the oven when cleaning.
2. Soak the parts in a solution of ammonia and water.
3. Reinstall after cleaning.
