The area used for the installation must be suitable for the
size, function, and protection (from elements) of the shelf
hood.

INSTALLATION
REQUIREMENTS
A. Space Requirements
A typical installation can be seen in Figure 1. Study Figure 1
before proceeding. The shelf hood requires an opening that
is 30" wide. It is recommended that the cabinet above the
cooktop- be a maximum of 15” high. This provides the
adequate space btween the range cooktop and the shelf
hood.
B. Electrical Requirements
A 120 Volt, 60 Hz, AC only, 20 Ampere fused electrical supply
is required (Time delay fuse or circuit breaker is
recommended). It is recommended that a separate circuit
serving only this appliance be provided.

VENTING REQUIREMENTS
Before you begin, determine where the ductwork will run.
For best performance, keep the length of ductwork and the
number of elbows to a minimum.
Illustrated are some of the more common methods. (Figures
2,3, and 4).
IMPORTANT: THE VENTING SYSTEM MUST TERMINATE
TO THE OUTSIDE. DO NOT TERMINATE THE VENT IN AN
ATTIC OR OTHER ENCLOSED SPACE. THIS MAY RESULT
IN A FIRE HAZARD.

CAUTION: Due to the amount of weight the shelf hood must
support, make sure the hood is mounted to two vertical 2x4
wall studs with the four lag bolts and into the wall covering
('h" sheet rock minimum) with the four anchor bolts. Lag
bolts and anchor bolts (eight in all) are supplied in the Instal
lation Assembly.
2. If the shelf hood is mounted to a wall that does NOT meet
the above recommendations, the weight of the microwave
oven may cause the hood to pull away from the wall resulting
in personal injury or property damage.
3. Mark a line on the back wall 15" down from the upper
cabinets centered between the side cabinets or the allotted
space. Use a level. (Figure 5).
