All Blodgett ovens are shipped in containers to
prevent damage. Upon delivery of your new oven:

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.

D

Uncrate the oven and check for internal dam­age. Ca rriers will accept claims for concealed
damage if notified within fifteen days of delivery
and the shipping container is retained for in­spection.

The Blodgett Oven Company cannot assume
responsibility for loss or damage suffered in

OVEN LOCATION

The well planned and proper placement of your
oven will result in long term operator convenience
and satisfactory performance.

Be sure to place the oven in an area which is ac­cessibleforproperoperationandservicing.

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 w all.

Ovens are supplied for operation on 208 volt or
220-240 volt installation. The thermostat, indicator
light a nd related switches are interconnected
through one power source supplied to the oven.

Before making any connection to this oven, check
the rating plate attached to the bodyback to as­sure that the voltage, phase and KW rating are
compatible with the electrical supply. See dia­gram.

All ovens, when installed, must be connected and
electrically grounded in accordance with local
codes, or in the absence of local codes, w ith the
National Electrical Code, ANSI/NFPA 70--- Latest
Edition and/or Canadian Electric Code CSA
C22.1 as applicable.

Wiring diagrams are located on the bodyback.

The supply conduit enters through the rear of the
oven and electrical connection is made to the ter­minal block secured to the panel at the back of the
control compartment. Electrical connection sizes
for a double 1400 oven are shown in “Electrical
Connection AWG” column of the Electrical Specifi­cations found on page 2 of this manual. Wiring is
sized for 75_C copper wire at 125% of ra ted input.
Reference is from the National Electric Code ANSI/
NFPA 70- Latest Edition.

General Baking Tips

PIZZA BAKING PROBLEMS

Uneven Bakes

D

Oven door open too long

D

Improper scaling of dough

D

Warped pans

Product Burning

D

Thermostat set too high

D

Product left in the oven too long

Dried Out Product

D

Oven temperature too low

D

Not using enough water in mix

Extended Baking Times

D

D

BAKING TIPS

D

The deck is intended for cooking pizza and
bread products, other types of food may be
cooked in pans or containers.

D

Scale dough for consistent product.

D

Proof dough to proper consistency .

D

Sicilian type pizzas require a longer baking
time.

D

Pizza in pans bake slower than those on
screens.

D

Alternateusebetweenupperandlowershelf.

D

Break bubbles that sometimes occur in baking.
(Usually occurs with refrigerator dough.)

D

Frequent needless opening of oven door
should be avoided.

D

Rotate placement of pizza in oven.

D

Refer to this manual for proper installation and
ventilation.

SUGGESTED TIMES AND TEMPERATURES

Pizza should be placed in pans or on screens
when baked in the oven.

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 7-1/2
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.

Te m p e ra t u r e

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 experi­mental initial bakes a t 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 tempera­tures in increments of 25_F (15_C). This will enable
you to determine the highest temperature a t which
you can bake and achieve quality results w ith
maximum production. Pull time is critical at high
temperatures. Shifting is unnecessary in most
cases.

Maintenance

Cleaning and Preventative Maintenance

CLEANING THE OVEN

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.

2. Dry the oven with a clean cloth.

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, and al­waysrubwiththegrainofthemetal.

Clean Cordierite decks with a triangular scraper
used for cleaning broiler grids. IMPORTANT --

DONOTusewateroranyotherliquidstoclean
the deck! Due t o the porosity of the Cordierite,

cracking and/or spalling w ill often result if water is
used.

Clean the aluminized interior portion of the oven
with a mild detergent. DO NOT use caustic solu­tionssuchasammonia,lyeorsodaash.DONOT
use domestic oven cleaners. Any of these prod­ucts 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.

PREVENTATIVE MAINTENANCE

The best preventative maintenance measures are,
the proper installation of the equipment and a pro­gram for routinely cleaning the ovens.

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 sup­ply before servicing or cleaning.
