Oven Description and Specications
Cooking in a convection oven di󰀨ers from cooking in a
conventional deck or range oven since heated air is con-
stantly recirculated over the product by a fan in an en-
closed chamber. The moving air continually strips away
the layer of cool air surrounding the product, quickly al-
lowing 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 advance-
ment in energy e󰀩ciency, reliability, and ease of opera-
tion. Heat normally lost, is recirculated within the cooking
chamber before being vented from the oven: resulting in
substantial reductions in energy consumption and en-
hanced 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 ship-
ping container is retained for inspection.
The Blodgett Oven Company cannot assume responsibil-
ity for loss or damage su󰀨ered in transit. The carrier as-
sumed 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 con-
struction.
Zephaire-100-E
• Oven body right side - 0” (0 cm)
• Oven body left side - 0” (0 cm)
• Oven body back - 0” (0 cm)
• Single and stacked oven bottom - 4-1/2” (11.4 cm)
Zephaire-200-E
• 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)
• Single and stacked oven 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.
• Do not place strong sources of heat such as open
ame ranges, griddles, or charbroilers near the
oven. If such an instance exists, it is highly recom-
mended to purchase a heat shield, available from
Blodgett.
• Note that if temperatures are too high, a safety shut-
down may occur.
• Failure to comply may invalidate the oven warranty.

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 tem-
perature to o󰀨set 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) low-
er 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 tem-
peratures 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 bak-
ing 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 tem-
perature.
2. Load the oven with product. Close the doors.
3. Set the thermostat to the baking temperature.
4. Turn the oven o󰀨.
5. Allow the product to set for 5-7 minutes with the fan
o󰀨. 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 o󰀨 when not viewing the product.
Leaving the lights on for extended periods of time short-
ens the bulb life considerably.

Maintenance
Cleaning and Preventative Maintenance
CLEANING THE OVEN
WARNING!!
Always clean the unit when it is cold.
WARNING!!
Be sure to read and follow the MSDS or
safety instructions on the bottle for your oven
cleaner.
Cleaning the Exterior
1. Saturate a cloth with stainless steel cleaner and wipe
down the exterior.
NOTE: Heat tint and heavy discoloration may be
removed with any non-caustic commercial
oven cleaner.
2. Dry the oven with a clean cloth.
Cleaning the Oven Interior
1. Remove the racks, rack supports and blower wheel
cover (back panel) from the oven. Soak the parts in a
solution of ammonia and water.
NOTE: To remove the blower wheel cover loosen
the screws in each corner. Then lift up and
out.
2. The porcelain interior can be cleaned with any com-
mercial oven cleaner. Be sure caustic cleaning com-
pounds DO NOT come in contact with the tempera-
ture probe, heating element, and blower wheel. Let
the cleaner sit for 10-20 minutes or the length of time
recommended on your cleaner.
3. Wipe out the cleaner with a wet cloth.
4. Reinstall the racks, rack supports and blower wheel
cover.
Weekly Cleaning
Be sure the air intake (cooling fan) behind the oven is free
of all lint, grease or other air ow inhibitors. Keeping the
air intake free of obstructions will extend the life of the
oven components.
