Oven Description and Specications
Cooking in a convection oven diers 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.

Ventilation
On gas models the installation of a proper ventilation sys-
tem cannot be over emphasized. This system removes
unwanted vapors and products of combustion from the
operating area.
This oven may be vented using either:
• A mechanically driven, canopy type, exhaust hood,
or
• A direct ue arrangement.
U.S. and Canadian installations
Refer to your local ventilation codes. In the absence of
local codes, refer to the National ventilation code titled,
“Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors from Commercial
Cooking Equipment”, NFPA-96-Latest Edition.
General export installations
Installation must conform with Local and National instal-
lation standards. Local installation codes and/or requirements may vary. If you have any questions regarding the
proper installation and/or operation of your Blodgett oven,
please contact your local distributor. If you do not have a
local distributor, please call the Blodgett Oven Company
at 0011-802-658-6600.
WARNING:
Failure to properly vent the oven can be hazardous to the health of the operator and may
result in operational problems, unsatisfactory
baking and possible damage to the equipment.
Damage sustained as a direct result of improper ventilation will not be covered by the
manufacturer’s warranty.
CANOPY TYPE EXHAUST HOOD
A mechanically driven, canopy type exhaust hood is the
preferred method of ventilation.
The hood should be sized to completely cover the equipment plus an overhang of at least 6” (15 cm) on all sides
not adjacent to a wall. The distance from the oor to the
lower edge of the hood should not exceed 7’ (2.1m).
The total makeup and exhaust air requirements for hood
capacity should be approximately 30 CFM (.85 m3) for
each oven section.
Installing the canopy hood draft diverter
Ovens ordered for hood venting are supplied with a draft
diverter. Install the draft diverter as follows:
1. Place the draft diverter on the oven back and slide it
up through the rectangular hole in the oven body top.

DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exhaust
hood is impractical the oven may be vented by a direct
ue arrangement.
WARNING!!
It is essential that the direct ue be installed
as follows. Incorrect installation will result in
unsatisfactory baking and oven damage.
The ue must be class B or better. The height of the ue
should rise 6-8 ft (2-2.5 m) above the roof of the building or any proximate structure. Never direct vent the oven
into a hood. The ue should be capped with a UL Listed
type vent cap to isolate the unit from external environmental conditions.
The direct vent cannot replace air consumed and vented
by the oven. Provisions must be made to supply the room
with sucient make-up air. Total make-up air requirements for each oven section should be approximately 30
CFM (.85 m3) per section. To increase the supply air entering the room, a ventilation expert should be consulted.

Installation
Gas Connection
GAS PIPING
A properly sized gas supply system is essential for maximum oven performance. Piping should be sized to provide a supply of gas sucient to meet the maximum de-
mand of all appliances on the line without loss of pressure
at the equipment.
Example:
NOTE: BTU values in the following example are for natu-
ral gas.
You purchase a Zephaire-100-G-ES to add to your existing cook line.
1. Add the BTU rating of your current appliances.
Pitco Fryer 120,000 BTU
6 Burner Range 60,000 BTU
Deck Oven 50,000 BTU
Total 230,000 BTU
2. Add the BTU rating of the new oven to the total.
Previous Total 230,000 BTU
Zephaire-100-G-ES 45,000 BTU
New Total 275,000 BTU
3. Measure the distance from the gas meter to the cook
line. This is the pipe length. Let’s say the pipe length
is 40’ (12.2 m) and the pipe size is 1” (2.54 cm).
4. Use the appropriate table to determine the total capacity of your current gas piping.
The total capacity for this example is 320,000 BTU. Since
the total required gas capacity, 275,000 BTU is less than
320,000 BTU, the current gas piping will not have to be
increased.
NOTE: The BTU capacities given in the tables are
for straight pipe lengths only. Any elbows or
other ttings will decrease pipe capacities.
Contact your local gas supplier if you have
any questions.

With the optional COOK & HOLD feature, meat is roasted
at lower temperatures for longer periods of time. This pre-
serves avor and tenderness and prevents over drying.
There are three phases in cook and hold roasting.
• Primary Cooking - controlled by the COOK & HOLD
TIMER. The meat is cooked at a low temperature
until approximately 2/3 done.
• Cooking from Stored Heat - when the primary cook
time expires, the oven automatically switches to
HOLD. The product continues to cook from the heat
stored in the oven. Meat must remain in the hold
cycle for a minimum of 1-1/2 to 2 hours before being
served.
• Hold - holds the product for several hours before
serving without loss of moisture or tenderness.

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 oset 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 re-
duce 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 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 shortens the bulb life considerably.

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 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.
The porcelain interior can be cleaned with any commercial oven cleaner. Be sure caustic cleaning compounds
DO NOT come in contact with the blower wheel and the
aluminized steel panel directly behind it.
1. Remove the racks, rack supports and blower wheel
from the oven.
2. Soak the parts in a solution of ammonia and water.
3. Reinstall after cleaning.
Weekly Cleaning
In addition to the daily cleaning it is necessary to clean
the air intakes on a weekly basis. Air intakes provide necessary cooling air to the internal components. They are
generally located on the rear and sides of the equipment.
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!!
Always disconnect the appliance from the
power supply before servicing or cleaning.
NOTE: If the oven is moved the restraint must be recon-
nected after the unit is returned to it’s regular position.
