VENTING REQUIREMENT
IMPORTANT:
•
NEVER exhaust air or terminate duct work into spaces
between walls, crawl spaces, ceiling, attics or garages.
All
exhaust must be ducted to the outside.
•
Hood 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.
•
Use metal/aluminum duct work only
.
•
A minimum of 6” round (standard for this range hood) must
be used to maintain maximum airflow efficiency
•
DO NOT use plastic vent.
•
DO NOT use 4” (10.2 cm) laundry-type wall caps
•
Fasten all connections with sheet metal screws and tape all
joints with certified Silver Tape or Duct Tape.
•
Use caulking to seal exterior wall or roof opening around the
cap.
Vent system must terminate to the outside (roof or
side wall).
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 6” or bigger vent work.
•
ALWAYS, when possible, reduce the number or transitions
and turns. If 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 airflow and decrease airflow, thus reduce duct size as
far away from opening as possible.
•
If turns or transitions are required: Install as far away from
opening and as far apart, between 2, as possible.
•
If available, also refer to stove top manufacturer’s height
clearance requirements and recommended hood mounting
height above range.
•
The size of the vent should be uniform.
•
Use no more than three 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 vent 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.
