Min 30" - Max 36"

36"

*shown with 12" duct cover

Minimum mount height between range top to hood bottom should be no less than 30”.

Maximum mount height should be no higher than 36”.

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 lose its performance and efficiency.

If available, also refer range manufacturer’s height clearance requirements and recommended hood mounting height above range.

Vertical Ducting:

6” round minimum (singe blower)

10” round minimum (dual, in-line, and external blowers)

No horizontal option available

Installation

DUCTING

A minimum of 6” round or 3-1/4” x 10” rectangular duct must be used to maintain maximum air flow efficiency for single blower and 10” round duct for dual, in-line, and external blowers.

Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%.

Also use calculation (on page 5) to compute 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.

If turns or transitions are required; install as far away from hood duct output and as far apart, between the two as possible.
