GE Profile™ Spacemaker® Convection/Microwave Oven

Dimensions and Installation Information (in inches)

Hood Exhaust Duct: Outside ventilation requires a HOOD EXHAUST DUCT. Read the

following carefully.
Exhaust Connection: The hood exhaust has been designed to mate with a standard

3-1/4" x 10" rectangular duct. If a round duct is required, a rectangular-to-round transition
adaptor must be used. Do not use less than a 6" diameter duct

Rear Exhaust: If a rear or horizontal exhaust is to be used, care should be taken to
align exhaust with space between studs, or wall should be prepared at the time it is
constructed by leaving enough space between the wall studs to accommodate exhaust.

Maximum Duct Length: For satisfactory air movement, the total duct length of
3-1/4" x 10" rectangular or 6" diameter round duct should not exceed 120 equivalent feet.

Elbows, Transitions, Wall and Roof Caps, etc., present additional resistance to airflow
and are equivalent to a section of straight duct which is longer than their actual physical
size. When calculating the total duct length, add the equivalent length of all transitions
and adaptors plus the lengths of all straight duct sections. The chart below shows the
approximate feet of equivalent length of some typical ducts.

Duct Equivalent Feet

A. Rectangular-To-round 5 ft.

Transition Adaptor

B. Wall Cap 40 ft.
C. 90° Elbow 10 ft.
D. 45° Elbow 5 ft.
E. 90° Elbow 25 ft.
F. 45° Elbow 5 ft.
G. Roof Cap 24 ft .
