IMPORTANT:

•

A minimum of 6" round (standard for this range hood) or 3-1/4 x 10" rectangular duct (purchased separately)

must be used to maintain maximum airflow efficiency.

•

Always use rigid type metal/aluminum ducts if available to maximize airflow when connecting to provided

duct.

Duct Run Calculation below to compute the total available duct run when using elbows, transitions

Please use

and caps.

•

ALWAYS, when possible, reduce the number or transitions and turns. If long duct run is required, increase

duct size from 6" to 7" or 8". If a reducer is used, install a long reducer instead of a pancake reducer. Reduc-

ing duct size will restrict airflow and decrease airflow, thus reduce duct size as far away from opening as pos-

sible.

•

If turns or transitions are required: Install as far away from opening and as far apart, between 2, as possible.

•

Minimum mount height between stove top to hood bottom should be no less than 28-inch*.

•

Maximum mount height between stove top to hood bottom should be no higher than 31-inch*.

•

It is important to install the hood at the proper mounting height. Hoods mounted too low could result in heat

damage and fire hazard; while hoods mounted too high will be hard to reach and will loose its performance

and efficiency.

•

If available, also refer to stove top manufacturer's height clearance requirements and recommended hood

mounting height above range.

* Due to different ceiling height configurations, recommended height may not be applicable.

Minimum Duct Size:

•

Round - 6" minimum

•

Rectangular - 3-1/4 x 10" minimum (requires a 6" to 3-1/4x10" adaptor, not supplied)
