Important
• A minimum of 6” round (standard for this range hood) or 3-1/4 x 10” rectangular duct (purchased sepa-
rately) must be used to maintain maximum airflow efficiency.
• Flexible 6” round duct, always use rigid type metal/aluminum ducts if available to maximize airflow
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 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.
• Reducing duct size will restrict airflow and decrease airflow, thus 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 pos-
sible.
• 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)
To calculate the length of the system you need, deduct the equivalent feet for each vent piece used in
the system from the recommended maximum duct run.
Duct Run Calculation example:
One roof cap, one 90º elbow, and one 45º elbow
used: 9ft + 5ft = 14 ft used.
Deduct 14 ft from 30ft, 16ft maximum available for
straight duct run. If no elbows are used, maximum
run is 30 ft (recommended).
