VENTING REQUIREMENTS

HEIGHT & VENTING REQUIREMENTS

For best operation, we recommend you:

allow 28-36” between the top of your cooking surface and the bottom of hood

vent vertically through the roof if possible

vent through a side wall if you can- not vent directly above your range hood

use 6” or 8” round (or 3-1/4 x 10” rectangular) metal ducting

use as few elbows as possible, with no more than three 90° elbows.

make sure there is at least 24” of straight vent between any elbows

use silver or duct tape to seal all joints in the vent system

use caulking to seal exterior open- ings around the cap

always use metal or aluminum ducts for maximum airflow

always keep the duct clean to en- sure proper airflow

DO NOT:

♦ terminate the vent system into an attic or other enclosed area

♦ use 4” (10.2 cm) laundry-type wall caps

♦ use plastic venting

WARNING

It is important to install the hood at the proper mounting height. Hoods mounted too low could result in heat damage and fire hazard. Hoods mounted too high will be hard to reach and will lose performance and efficiency.
