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.

Minimum mount height between range top to hood bottom should be no less than 24”.

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 re hazard; while hoods

mounted too high will be hard to reach and will

lose its performance and e󰀩ciency.

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

Installation – Mounting Height & Clearance

A minimum of 8” round duct must be used to

DUCTING

maintain maximum air ow e󰀩ciency for single

internal blower and 10” round duct for dual internal blower.

Always use rigid type metal ducts only. Flexible

ducts could restrict air ow by up to 50%.

Also use calculation (on page 5) to compute total

available duct run when using elbows, transitions and caps.
