• Typical installation
The height from the countertop to the bottom of the hood is 30” to 36”.
These hoods are not recommended to be used over indoor grills.
1. Choose vent options
The hood is designed to be used for vertical discharge as shown below.
Note: see also Fig. 1-2-3 for Cabinet preparation.
Install a 1/2” conduit from the service panel long enough to reach the hood
once it is installed. Power supply must be rated for 120 VAC, 60Hz. 15 or 20 A.

TABLE 2. DUCTWORK INSTALLATION GUIDELINES
For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the
garage or into any enclosed space).
Keep duct runs as short and straight as possible.
Duct ttings (elbows and transitions) reduce air ow efciency.
Back to back elbows and „S“ turns give very poor delivery and are not recommended.
A short straight length of duct at the inlet of the remote blower gives the best delivery.
Transition to duct from the integral blower to remote duct transition as close as possible.
In order opreference, use:
1st. 10” round duct
2nd. 8round duct
3rd. 3-1/4” x 14” duct
4th. 7” round duct
5th. 3-1/4” x l0” duct
6th. 6” round duct
The use of exible metal round duct should only be used when no other duct tting exists. Limit use to short
lengths
1. Prepare duct and conduit cut outs, see gures
1 and 2 as needed.
