NOTE: * - Multiple Twist Drill
Cooking in a convection oven differs 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 ef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 suffered 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.
• Oven body right side - 6” (15 cm)
• Oven body left side - 6” (15 cm)
• Oven body back - 6” (15 cm)
• Oven body bottom - 4.5” (11.4 cm)
The following clearances must be available for servicing.
• Oven body sides - 12” (30 cm)
• Oven body back - 12” (30 cm)
NOTE: On gas models, routine servicing can usually
be accomplished within the limited movement
provided by the gas hose restraint. If the oven
needs to be moved further from the wall, the
gas must rst be turned off and disconnected
from the oven before removing the restraint.
Reconnect the restraint after the oven has been
returned to its normal position.
It is essential that an adequate air supply to the oven be
maintained to provide a sufcient ow of combustion and
ventilation air.
• Place the oven in an area that is free of drafts.
• 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. Tripping of the blower motor’s
thermal overload device is caused by an excessive
ambient temperature on the right side of the oven.
This condition must be corrected to prevent perma-
nent damage to the oven.
• The location must provide adequate clearance for
the air opening into the combustion chamber.
Before making any utility connections to this oven, check
the rating plate to be sure the oven specications are
compatible with the gas and electrical services supplied
for the oven.
1. Remove the combustion compartment cover. The rat-
ing plate is attached to the frame on the left side of
the combustion compartment.

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 Remov-
al of Smoke and Grease Laden Vapors from Commercial
Cooking Equipment”, NFPA-96-Latest Edition.
Australia and general export installations
Installation must conform with Local and National instal-
lation standards. Local installation codes and/or require-
ments 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 haz-
ardous to the health of the operator and may
result in operational problems, unsatisfactory
baking and possible damage to the equip-
ment.
Damage sustained as a direct result of im-
proper 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 equip-
ment 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 diverter over the ue connector with the
open area facing the front of the oven.
2. Secure both ends with the sheet metal screws pro-
vided.

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 with a diameter of 6”
(15 cm). 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 sufcient make-up air. Total make-up air require-
ments for each oven section should be approximately 30
CFM (.85m3) per section. To increase the supply air en-
tering the room, a ventilation expert should be consulted.
Installing the draft hood
Ovens ordered for direct venting are supplied with a draft
hood. Install the draft hood as follows:
1. Place the draft hood over the ue connector.
2. Secure both ends with the sheet metal screws pro-
vided.

Installation
Gas Connection
GAS PIPING
A properly sized gas supply system is essential for maxi-
mum oven performance. Piping should be sized to pro-
vide a supply of gas sufcient 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
natural gas.
You purchase a Zephaire-G 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-G 60,000 BTU
New Total 290,000 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 ca-
pacity of your current gas piping.
The total capacity for this example is 320,000 BTU. Since
the total required gas pressure, 290,000 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 ques-
tions.

• Inlet Pressure - the pressure of the gas before it
reaches the oven.
• Manifold Pressure - the pressure of the gas as it
enters the main burner(s).
• Min - the minimum pressure recommended to oper-
ate the oven.
• Max - the maximum pressure at which the manufac-
turer warrants the oven’s operation.
Each oven is supplied with a regulator to maintain the
proper gas pressure. The regulator is essential to the
proper operation of the oven and should not be re-
moved. It is preset to provide the oven with 3.5” W.C.
(0.87 kPa) for natural gas and 10.5” W.C. (2.50 kPa) for
Propane at the manifold.
DO NOT INSTALL AN ADDITIONAL REGULATOR
WHERE THE OVEN CONNECTS TO THE GAS SUPPLY
UNLESS THE INLET PRESSURE IS ABOVE MAXIMUM.
Prior to connecting the oven, gas lines should be thor-
oughly purged of all metal lings, shavings, pipe dope,
and other debris. After connection, the oven should be
checked for correct gas pressure.
The oven and its individual shutoff valve must be discon-
nected from the gas supply piping system during any
pressure testing of that system at test pressures in ex-
cess of 1/2 psig (3.45kPa).
The oven must be isolated from the gas supply piping
system by closing its individual manual shutoff valve dur-
ing any pressure testing of the gas piping system at test
pressures equal or less than 1/2 psig (3.45kPa).
