3. DO NOT deep fry fat in the oven. The fat could
overheat and be hazardous to handle.
4. Pierce the skin of potatoes, tomatoes and similar
foods before cooking with microwaves. When
the skin is pierced, steam escapes evenly.
5. DO NOT place popcorn bags in this oven as
they may ignite.
6. DO NOT use regular cooking thermometers in
this oven when cooking with microwaves. Most
cooking thermometers contain mercury and may
cause an electrical arc, malfunction or damage

INSTALLATION
Owner's Manual for
DUKE DG2 Speed Oven
Unpacking Oven
• Inspect the oven for damage such as dents in
the door or inside the oven cavity.
• Report any dents or breakage to source of
purchase immediately. Do not attempt to use
oven if it is damaged.
• Remove all materials from oven interior.
• If oven has been stored in an extremely cold
area, wait a few hours before connecting power.
Radio Interference
Microwave operation may cause interference
to radio, television or a similar oven. Reduce or
eliminate interference by taking the following
precautions:
• Clean the door and sealing surfaces of the oven
according to the instructions in the CARE AND
CLEANING section.
• Place radios, televisions and similar electronic
devices as far as possible from the oven.
• Use a properly installed antenna on radio,
television and similar electronic devices to obtain
stronger signal reception.
Oven Placement
• Do not install oven adjacent to a source of heat
such as pizza oven or deep fat fryer. This could
cause the microwave oven to operate improperly
and shorten the life of electrical parts.
• Install the oven on a level countertop surface.
• If provided, place warning label in an obvious
place close to the microwave oven.
• The outlet should be located so that the plug is
accessible when the oven is in place.
Oven Clearances
• Allow at least 6 in. (15.2 cm) of clearance on top.
• No clearance is required at the back.
• A clearance of 0.5 in. (1.3 cm) is necessary
between side panels and adjacent walls.
• A clearance of 3 in. (7.6 cm) is required to
operate two ovens side by side or the clearance
to an adjacent similar heat source.
• Proper airow around the oven cools electrical
components. With restricted airow, the oven
may not operate properly and life of the electrical
parts is reduced.
• Install the oven so the oven bottom is at least 36
in. (93.0 cm) above the oor.
• When stacking ovens, ONLY use the Duke
stacking frame.
