DELIVERY AND INSPECTION
All Blodgett ovens are shipped in containers to
prevent damage. Upon delivery of your new oven:
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.
D 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.
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.
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 beĆ
tween the oven and any combustible or nonĆcomĆ
bustible construction.
D Oven body right side - 6" (15 cm)
D Oven body left side - 6" (15 cm)
D Oven body back - 6" (15 cm)
D Oven body bottom - 6" (15 cm)
The following clearance must be available for serĆ
vicing.
D Oven body left side - 12" (30.5 cm)
NOTE: On gas models, routine servicing can usuĆ
ally be accomplished within the limited
movement provided by the gas hose reĆ
straint. If the oven needs to be moved furĆ
ther from the wall, the gas must first be
turned off and disconnected from the oven
before removing the restraint. Reconnect
the restraint after the oven has been reĆ
turned to its normal position.
It is essential that an adequate air supply to the
oven be maintained to provide a sufficient flow of
combustion and ventilation air.
D Place the oven in an area that is free of drafts.
D Keep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
D Do not place the oven on a curb base or seal to
a wall. This will restrict the flow of air and prevent
proper ventilation. Pilot outages or yellow, floatĆ
ing flames on the main burners are indicative of
a lack of secondary air.
D The oven must be installed with the legs supĆ
plied by the manufacturer.
Before making any utility connections to this oven,
check the rating plate to be sure the oven specifiĆ
cations are compatible with the gas and electrical
services supplied for the oven. The rating plate is
located on the inside of the burner door.

bility of the installer, or dealer. Since these adjustĆ
ments are not considered defects in material or
workmanship, they are not covered by the Original
Equipment Warranty. They include, but are not
limited to:
D calibration of the thermostat
D adjustment of the doors
D burner adjustments
D leveling
D testing of gas pressure
D tightening of fasteners
No installation should be considered complete

Installation
Ventilation
Blodgett gas deck ovens are direct fired. Heat and
flue products from the burners are introduced diĆ
rectly into the baking compartment. As a result,
improper venting can have a detrimental effect on
the baking characteristics of the oven. A properly
designed ventilation system will allow the oven to
function properly, while removing unwanted vaĆ
pors and products of combustion from the operĆ
ating area.
This oven may be vented using either:
D A mechanically driven, canopy type, exhaust
hood, or
D A direct flue arrangement.
U.S. and Canadian installations
Refer to your local ventilation codes. In the abĆ
sence of local codes, refer to the National ventilaĆ
tion code titled, Standard for the Installation of
Equipment for the Removal of Smoke and Grease
Laden Vapors from Commercial Cooking EquipĆ
ment", NFPAĆ96ĆLatest Edition.
General export installations
Installation must conform with Local and National
installation 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 disĆ
tributor, please call the Blodgett Oven Company at
0011Ć802Ć860Ć3700.
THE BLODGETT OVEN COMPANY CANNOT ASĆ
SUME RESPONSIBILITY FOR LOSS OR DAMAGE
SUFFERED AS A RESULT OF IMPROPER INSTALĆ
LATION.
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 floor to the lower edge of the hood should
not exceed 7' (2.1m).
The capacity of the hood should be sized approĆ
priately with provisions for an adequate supply of
make up air. Capacity is generally expressed in
ft3/min (CFM). 1 CFM of natural gas burned with
just enough air for complete combustion proĆ
duces 11 CFM of combustion products. In virtually
all appliances some excess air is used. This volĆ
ume of excess air is added to the flue products
flowing from the appliance.
NOTE: Consult your local exhaust hood contracĆ
tor for your specific installation.
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 flue connector with
the open area facing the front of the oven. See
Figure 6.
2. Secure both ends with the sheet metal screws
provided.
Draft Diverter
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 damĆ
age to the equipment.
Damage sustained as a direct result of imĆ
proper ventilation will not be covered by
the Manufacturer's warranty.

DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exĆ
haust hood is impractical the oven may be vented
by a direct flue arrangement.
Installation
Ventilation
Flue
WARNING!!
It is essential that the direct flue be
installed as follows. Incorrect installation
will result in unsatisfactory baking and
oven damage.
The flue must be class B or better with a diameter
of 10" (25.4 cm). The height of the flue should rise
6Ć8 ft (2Ć2.5 m) above the roof of the building or any
proximate structure. Never direct vent the oven
into a hood. The flue should be capped with a UL
Listed type vent cap to isolate the unit from exterĆ
nal environmental conditions.
The direct vent cannot replace air consumed and
vented by the oven. Provisions must be made to
supply the room with sufficient makeĆup air. Total
makeĆup air requirements for each oven section
should be approximately 30 CFM per section. To
increase the supply air entering the room, a venĆ
tilation 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 flue connector.
See Figure 7.
2. Secure both ends with the sheet metal screws
provided.

Figure 7
VENTING PROBLEMS
Blodgett gas deck ovens use the natural principal
of heat rising as the basic method of ventilation. If
the venting of any deck oven is either restricted or
forced in any way the baking characteristics of the
oven will be adversely affected.
Examples of forced venting include:
D installation of a fan in a direct vent pipe
D use of a canopy type hood without the draft diĆ
verter
Examples of restricted venting include:
D use of tees and elbows
D long horizontal runs
Insufficient makeĆup air can cause heated air and
combustibles to remain in the oven shortening the
life of the components.
