4Island Mount Range Hood Installation Instructions
HEIGHT AND CLEARANCE 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 airow efciency.
Flexible 6" round duct provided for convenience, always
use rigid type metal/aluminum ducts if available to
maximize airow when connecting to provided duct.
Please use Duct Run Calculation below to compute the
total available duct run when using elbows, transitions
and caps.
Always, when possible, reduce the number of transitions
and turns. If long duct run is required, increase duct size
from 6" to 7"- 8". If a reducer is used, install a long
reducer instead of a pancake reducer. Because reducing
duct size will restrict and decrease airow, reduce duct
size as far away from opening as possible.
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 bot-
tom should be no less than 28".
Maximum mount height between stove top to hood bot-
tom should be no higher than 31".
It is important to install the hood at the proper mounting
height. Hoods mounted too low could result in heat dam-
age and re hazard; hoods mounted too high will be hard
to reach and will lose performance and efciency.
If available, also refer to stove top manufacturer’s height
clearance requirements and recommended hood
mounting height above range.
Note: Due to different ceiling height congurations,
recommended height may not be applicable.
Minimum Duct Size
Round - 6" minimum
Rectangular - 3-1/4" x 10" minimum (requires a 6" to 3-1/4" x 10" adaptor, not supplied)
