oven will result in long term operator convenience
and satisfactory performance.
D
D
Inspect the shipping container for external damĆ
age. 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 damĆ
age. Carriers will accept claims for concealed
damage if notified within fifteen days of delivery
and the shipping container is retained for inĆ
spection.
Be sure to place the oven in an area which is acĆ
cessible for proper operation and servicing.
It is essential that ventilation air not be obstructed
in any way if proper operation is to be assured. A
minimum of two inches (5 cm) must be maintained
between both the sides and the rear of the unit and
any wall.
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.

General Baking Tips
PIZZA BAKING PROBLEMS
SUGGESTED TIMES AND TEMPERATURES
Uneven Bakes
Pizza should be placed in pans or on screens
when baked in the oven.
D
D
D
Oven door open too long
Improper scaling of dough
Warped pans
Time
Baking time will vary with the amount of garnish on
the top of the pizza. Generally speaking, pizzas
baked in pans should bake in approximately 7Ć1/2
to 12 minutes. Pizza baked on screens should
bake in approximately 5 to 7 minutes. Raising the
temperature to accelerate baking time is effective
up to a point. Then the quality of the bake begins
to lessen.

The deck is intended for cooking pizza and
bread products, other types of food may be
cooked in pans or containers.
Scale dough for consistent product.
Proof dough to proper consistency.
Sicilian type pizzas require a longer baking
time.
Pizza in pans bake slower than those on
screens.
Alternate use between upper and lower shelf.
Break bubbles that sometimes occur in baking.
(Usually occurs with refrigerator dough.)
Frequent needless opening of oven door
should be avoided.
Rotate placement of pizza in oven.
Refer to this manual for proper installation and
ventilation.
11
The ideal temperature for baking pizza pies will
vary depending on the type of pie and the method
of baking. It is suggested that you attempt experiĆ
mental initial bakes at 450_F 232_C), making note
of the time required to achieve a firm crust. If the
cheese breaks down too quickly or scorches, you
should then lower your temperature and lengthen
your baking time. If faster production is desired,
attempt additional bakes raising baking temperaĆ
tures in increments of 25_F (15_C). This will enable
you to determine the highest temperature at which
you can bake and achieve quality results with
maximum production. Pull time is critical at high
temperatures. Shifting is unnecessary in most
cases.

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.
The best preventative maintenance measures are,
the proper installation of the equipment and a proĆ
gram for routinely cleaning the ovens.
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 nonĆ
toxic industrial stainless steel cleaner. Heat tint
and heavy discoloration may be removed with any
nonĆtoxic commercial oven cleaner.
1. Apply cleaners when the oven is cold, and alĆ
ways rub with the grain of the metal.
Clean Cordierite decks with a triangular scraper
used for cleaning broiler grids. IMPORTANT DO NOT use water or any other liquids to clean
the deck! Due to the porosity of the Cordierite,
cracking and/or spalling will often result if water is
used.
Clean the aluminized interior portion of the oven
with a mild detergent. DO NOT use caustic soluĆ
tions such as ammonia, lye or soda ash. DO NOT
use domestic oven cleaners. Any of these prodĆ
ucts will damage the aluminum coating.
Daily Cleaning
D
Remove residue from beneath the doors with a
small broom or brush.
Weekly Cleaning
D
Brush out the control area.
6 Month Cleaning
D
Clean secondary air ducts and air entry ports.
12
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 the
factory, the factory representative or a local
Blodgett service company.
WARNING!!
Disconnect the oven from the power supĆ
ply before servicing or cleaning.
