2. MOUNTING HEIGHT
4. VENTING METHODS
FOR THE MOST EFFICIENT & QUIET OPERTION:
A distance of 26” to 30” is recommended between stove top and the bottom of range
hood.
If the hood is mounted too low this could result in heat and/or fire hazard. If the hood is
mounted too high the controls will be hard to reach, and the hood will lose its
performance and efficiency.
3. VENTING REQUIREMENTS:
It is recommended that the range hood be vented vertically through the roof with a
minimum of 6” or larger vent work.
ALWAYS, when possible, reduce the number of transitions and turns in the
ducting. If a long duct run is required, increase duct size from 6” to 7” or 8”. If a
reducer is used, install a long reducer instead of a pancake reducer. Reducing duct
size will restrict/decrease airflow.
V
The size of the vent should be uniform.
Use no more than three 90° elbows in the duct run.
Make sure there is a minimum of 24” of straight vent between the elbows if more than one
elbow is used
IMPORTANT:
NEVER exhaust air or terminate ductwork into crawl spaces, between walls, ceiling,
attics, or garages. All exhaust must be ducted to the outside.
Do not use plastic ventilation
Do not use 4” laundry-type wall caps
ROOF VENTING
(2nd choice) This is the most
efficient way and highly
recommended. Ducting goes
vertically above the range
hood through the house’s
roof.
SIDE WALL VENTING
(3rd choice) Ducting goes
through the kitchen ceiling
from the top of the hood and
then through a nearby
exterior wall.
BACK WALL VENTING
(1
st
choice) Ducting goes up
straight inside upper cabinet
then turn and goes
horizontally straight through
an exterior wall from the
back of the hood. This will
be the shortest ducting length
