• Duct system must terminate to the outside (roof or side wall).
• DO NOT
terminate the duct system in an attic or other enclosed area.
• DO NOT
use 4” (10.2 cm) laundry-type wall caps.
• Use metal/aluminum duct only. Rigid metal/aluminum vent is recommended.
• DO NOT
use plastic duct.
•
Always keep the duct clean to ensure proper airflow.
•
Calculate the following figures before installation:
1. Distance from the floor to the ceiling.
2.
Distance from countertop/stove to range hood (recommend* 28” to 36”).
3. Height of hood and duct cover.
For the most efficient & quiet operation:
•
A distance of 28” to 36” is recommended* between stove top and the bottom of range hood.
•
It is recommended that the range hood be vented vertically through the roof through 8” or bigger
round metal/aluminum duct work.
• The size of the duct should be uniform.
•
Use no more than three 90° elbows.
•
Make sure there is a minimum of 24” (61 cm) of straight duct between the elbows if more than one
elbow is used.
• DO NOT
install two elbows together.
•
The length of duct system and number of elbows should be kept to a minimum to provide efficient
performance.
•
The duct system must have a damper. If roof or wall cap has a damper,
DO NOT
use damper (if
supplied) on top of the range hood.
•
Use aluminum foil tape to seal all joints in the duct system.
•
Use caulking to seal exterior wall or roof opening around the cap.
USE 8” ROOF OR WALL VENT
CAP MINIMUM
.
IMPORTANT:
• A minimum of a 8” round duct (standard for this range hood) must be used to maintain maximum
airflow efficiency. There is also an option to use a 10” round duct size for this unit.
•
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 total available duct run when using elbows,
transitions and caps.
•
ALWAYS, when possible, reduce the number or transitions and turns in the duct run. If a long duct
run is required, increase the duct size from 8” to 10”. If a reducer is used, install a long reducer
instead of a pancake reducer. Reducing the duct size will restrict airflow and decrease efficiency.
•
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 bottom should be no less than 28-inch*.
•
Maximum mount height between stove top to hood bottom should be no higher than 36-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.
Minimum Duct Size:
•
Round - 8” minimum
•
Round - 10” recommended/optional
* Due to different ceiling height configurations, recommended height may not be applicable.
