•
Vent system must terminate to the outside (roof or side wall).
• DO NOT
terminate the vent system in an attic or other enclosed area.
• DO NOT
use 4” or 5” laundry-type wall caps. Use a 6” or larger Wall/Roof Cap.
•
Use metal/aluminum vent only. We recommend using Rigid instead of Flex duct.
•
Always keep the duct clean to ensure proper airflow.
For the most efficient & quiet operation:
•
It is recommended that the range hood be vented with a 6” or bigger round metal/aluminum vent
work.
•
The size of the vent should be uniform.
•
Use no more than two 90° elbows.
•
Make sure there is a minimum of 24” (61 cm) of straight vent between the elbows if more than one
elbow is used.
•
DO NOT install two elbows together.
•
The length of vent system and number of elbows should be kept to a minimum to provide efficient
performance.
•
Use aluminum foil tape to seal all joints in the vent system.
•
Use caulking to seal exterior wall or roof opening around the cap.
•
Use 45 degree elbows instead of 90 degree elbows when possible.
IMPORTANT:
•
A minimum of a 6” round duct (standard for this range hood) must be used to maintain maximum
airflow efficiency.
•
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 6” to 8”. 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 Duct Size:
•
Round - 6” minimum
