Introduction
Oven Description and Specifications
Cooking in a conveyor 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 continually strips away the layer of cool air surrounding the product, quickly allowing the heat t o penetrate. The result is a high quality product, cooked
at a lower temperature in a shorter amount of time.
Blodgett conveyor ovens represent the latest advancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recirculated within the cooking chamber before being
vented from the oven: resulting in substantial reductions in energy consumption, a cooler kitchen
environment and enhanced oven performance.

and satisfactory performance.
The following clearances must be maintained between the oven and any combustible or non-combustible construction.
D
Oven body sides --- 20” (51 cm)
D
Oven body back --- 2” (5 cm)
The following clearances must be available for servicing.
D
Oven body sides --- 38” (96.5 cm)
D
Oven body back --- 28” (71 cm)
NOTE: On gas models, routineservicingcan usu-
ally 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 first be
turned off and disconnected from the oven
before removing the restraint. Reconnect
the restraint after the oven has been returned to its regular 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 combustiblessuch 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 to the blower motors. This
condition must be corrected to prevent permanent damage to the oven.
VENTILATION
Ongasmodelsthenecessityforaproperlydesigned and installed ventilation system cannot be
over emphasized. This system allows the oven to
function properly while removing unwanted vapors and products of combustion from the operating area.
This oven must be vented with a properly designed mechanically driven exhaust hood. The
hood should be sized to completely cover the
equipment plus an overhang of at least 6” (15cm)
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 appropriately and provisions
should be made for adequate makeup air.

GAS PIPING
A properly sized gas supply system is essential for
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 MT3270 conveyor oven to add to
your existing cook line.
1. Addthe 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
MT3270 150,000 BTU
New Total 380,000 BTU
3. Measure the distance from the gas meter to
the cook line. This is the pipe length. Let’s say
thepipelengthis20’(6.1m)andthepipesize
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 465, 000
BTU. Since the total required gas pressure,
380,000 BTU is less than 465,000 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 fittings will decrease pipe capacities. Contact your local gas supplier if you
have any questions.

PRESSURE REGULATION AND TESTING
MT3270 ovens are rate d at 150,000 BTU/Hr. (44
kW/Hr.) Australian ovens are rated at 173 MJ/Hr.
for natural gas and 158 MJ/Hr. for propane. Each
oven has been adjusted at the factory to operate
with the type of gas specified on the rating plate
attached to the left side of the control panel.
Each oven is supplied with a regulator to maintain
thepropergaspressure.The regulator is essen-
tial to the proper operation of the oven and
shouldnot be removed. It is preset to provide the
oven with 3.5” W.C. (0.87 kPa) for natural gas and
10.0” W.C. (2.50 kPa) for Propane while the flame
is on. The regulator is located on top of the gas
valve, between the manual shutoff and solenoid
valves.
DO NOT INSTALL AN ADDITIONAL REGULATOR
WHERE THE OVEN CONNECTS TO THE GAS
SUPPLY UNLESS THE SUPPLY EXCEEDS THE
MAXIMUM.
NOTE: The maximum gas supply pressure to the
oven is 10.5” W.C. (2.61 kPa) for natural gas
and 13” W.C. (3.2 kPa) for Propane gas. The
minimum gas supply pressure to the oven is
4.5” W.C. (1.1 kPa) for natural gas and 11.0”
W .C. (2.74 kPa) for Propane gas.
Installation must conform with local codes, or in
the absence of local codes, with the National Fuel
Gas Code, NFPA54/ANSI Z223.1 ---Latest Edition,
the Natural Gas Installation Code CAN/CGAB149.1 or the Propane Installation Code, CAN/
CGA-B149.2 as applicable.
The oven and its individual shutoff valve must be
disconnected from the gas supply piping system
during any pressure testing of t hat system at test
pressuresinexcessof1/2psig(3.45kPa).
The oven must be isolated from the gas supply
piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas piping system at test pressures equal or less

GAS HOSE RESTRAINT
If the oven is mounted on casters, a commercial
flexible connector with a minimum of 3/4” (1.9 cm)
inside diameter must be used along with a quick
connect device.
The restraint, supplied with the oven, must be
used to limit the movement of the unit so that no
strain is placed upon the flexible connector. The
restraint should be fastened to the base frame of
the oven as close to the flexible connector as possible. It should be short enough to prevent any
strain on the connector. With the restraint fully
stretched the connector should be easy to install
and quick connect.
The restraint (ie: heavy gauge cable) should be attached without damaging the building. DO NOT
use the gas piping or electrical conduit for the attachment of the permanent end of the restraint!
Use anchor bolts in concrete or cement block. On
wooden walls, drive hi test wood lag screws into
the studs of the wall.
WARNING!!
If the restraint is disconnected for any
reason it must be reconnected when the
oven is returned to its original position.
U.S. and Canadian installations
The connector must comply with the Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69 or Connectors For Moveable Gas Appliances CAN/CGA-6.16 and a quick disconnect
device that complies with the Standard for QuickDisconnect Devices for Use With Gas Fuel, ANSI
Z21.41 or Quick Disconnect For Use With Gas Fuel
CAN 1-6.9. Adequate means must be provided to
limit the movement of the appliance without depending on the connection and the quick disconnect device or its associated piping.
A drip leg must be used at each appliance. Refer
to NFPA54/ANSI Z223.1 - Latest Edition (National
Fuel Gas Code) for proper drip leg installation.
