Oven Description and Specifications
Cooking in a convection oven differs 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 con-
tinually strips away the layer of cool air surround-
ing the product, quickly allowing the heat to pene-
trate. The result is a high quality product, cooked
at a lower temperature in a shorter amount of time.
Blodgett convectionovens represent the latest ad-
vancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recircu-
lated within the cooking chamber before being
vented from the oven: resulting in substantial re-
ductions in energy consumption and enhanced
oven performance.

tion system cannot be over emphasized. This sys-
tem removes unwanted vapors and products of
combustion from the operating 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 ab-
sence of local codes, refer to the National ventila-
tion code titled, “Standard for the Installation of
Equipment for the Removal of Smoke and Grease
Laden Vapors from Commercial Cooking Equip-
ment”, NFPA-96-Latest Edition.

hazardous to the health of the operator
and may result in operational problems,
unsatisfactory baking and possible dam-
age to the equipment.
Damage sustained as a directresult 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
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 total makeup and exhaust air requirements for
hood capacity should be approximately 30 CFM
(.85 m

Gas Connection
GAS PIPING
A properly sized gas supply system is essentialfor
maximum oven performance. Piping should be
sized to provide a supply of gas sufficient to meet
the maximum demand 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 DFG-100 XCEL convection oven to
add to your existing cook line.
1. Add the BTU rating of your currentappliances.
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 to-
tal.
Previous Total 230,000 BTU
DFG-100 X
CEL (high rate) 80,000 BTU
New Total 310,000 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 to-
tal capacity of your current gas piping.
The total capacity for this example is 320,000
BTU. Since the total required gas pressure,
310,000 BTU is less than 320,000 BTU, the
current gas piping will not have to be in-
creased.
NOTE: The BTU capacities given in the tables are
for straight pipe lengths only. Any elbows
or other fittings will decrease pipe capaci-
ties. Contact your local gas supplier if you
have any questions.
