Oven Description and Specications
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 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.
Blodgett convection ovens represent the latest advancement in energy efciency, 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 and enhanced 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
notied within fteen days of delivery and the shipping container is retained for inspection.
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 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 construction.
DFG100
• Oven body right side - 2” (5cm)
• Oven body left side - 2” (5cm)
• Oven body back - 0” (0cm)
• Oven body bottom - 6” (15cm)
DFG200
• Oven body right side - 6” (15cm)
The following clearances must be available for servicing.
• Oven body sides - 12” (30cm)
• Oven body back - 12” (30cm)
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 sufcient 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.
• NSF requires 6” of clearance on the bottom and
sides of the unit for cleaning. Do not place the oven
on a curb base or seal to a wall.
• 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 specications are
compatible with the gas and electrical services supplied
for the oven.
1. Pull out control panel. The rating plate attached to the
inside of the control compartment.
• Oven body left side - 6” (15cm)
• Oven body back - 6” (15cm)
• Oven body bottom - 6” (15cm)

hole on the back of an oven. This includes:
• any unit, single or stacked, without a back panel.
• any holes in stacked units not used for mounting
stacking brackets.
1. Locate the 5/16” bolts that were shipped with the
oven.
2. Install the bolts as shown.

LEG ATTACHMENT
1. Push the oven onto a lift with the bottom of the oven
down.
2. Align the threaded stud in each leg with the nut located inside each bottom corner of the oven frame. Turn
the legs clockwise and tighten to the nearest full turn.
3. Align the two leg plate holes in each leg with those
in the oven bottom. Secure each leg using two 1/2”
bolts.
NOTE: If using casters see CASTER ASSEMBLY
before proceeding.
4. Level the oven by screwing the adjustable leg feet in
or out as necessary.
CASTER ASSEMBLY
NOTE: Install the locking casters on the front of the
oven. Install the non-locking casters on the back
of the oven.
NOTE: Use a gas hose restraint on all units with casters.
Casters for Single and Double Stacked Ovens:
1. Attach the legs as described.
2. Pry the adjustable feet out of the legs.
3. Insert one caster into each leg as shown. Tighten the
lock nuts to secure the casters.

DOUBLE SECTION ASSEMBLY
NOTE: Old style ovens refer to units with painted ex-
posed rear angle. New style ovens refer to units
with rear angle iron enclosed in steel.
The following instructions apply to stacking two new style
ovens.
1. Secure the short legs to the bottom sections as described.
2. Place the upper section in position on top of the lower
oven.
3. Attach the stacking brackets using the remaining
5/16” bolts shipped with the ovens.
4. Attach the ue connector.
The following instructions apply to stacking a new style
oven on an old style oven.
1. Secure the short legs to the bottom sections as described.
2. Place the upper section in position on top of the lower
oven.
3. Attach the stacking brackets using the remaining
5/16” bolts shipped with the ovens.
4. Drill a clearance hole for a 5/16” bolt in the angle iron
of the old style oven. Use the holes in the stacking
brackets as a pilot.
5. Attach the stacking brackets to the old style oven with
the 5/16” bolts and nuts provided in the kit.
6. Attach the ue connector.
WARNING:
When stacking ovens be sure to remove the
single oven ue boxes prior to attaching
three-piece connector.
OVEN LEVELING
After assembly, the oven should be leveled and moved to
the operating location.
