INSTALL DUCTWORK

VENTING REQUIREMENTS
Determine which venting method is best for your
application. Ductwork can extend either through
the wall or the roof.
A straight, short duct run will allow the hood to per-
form most efficiently. Long duct runs, elbows, and
transitions will reduce the performance of the hood.
Use as few of them as possible. Larger ducting
may be required for best performance with longer
duct runs. The length of the ductwork and the num-
ber of elbows should be kept to a minimum to pro-
vide efficient performance.
The size of the ductwork should be uniform. Do not
install two elbows together. Use 2” duct tape to
seal all joints in the ductwork system.
Install a roof or wall cap. Connect round metal
ductwork to cap and work back towards hood loca-
tion. Use caulking to seal exterior wall or floor
opening around the cap.
.
Flexible ductwork is not recommended. Flexible
ductwork creates back pressure and air turbulence
that greatly reduces performance.
USE ONLY
METAL DUCTWORK.
Make sure there is proper
clearance within the wall or floor for exhaust duct
before making cutouts. Do not cut a joist or stud
unless absolutely necessary. If a joist or stud must
be cut, then a supporting frame must be con-
structed.
CALCULATE THE DUCT RUN LENGTH
The duct run should not exceed 35 equivalent feet
if ducted with the required minimum of 6” round
duct. Calculate the length of the ductwork by add-
ing the equivalent feet in
FIGURE 2
for each piece
of duct in the system. An example shown in
FIG-
URE 3.
For the best results, do not use more than three
90
∘
elbows in a system. Make sure that there is a
minimum of 24” of straight duct between elbows if
more than one is used. DO NOT install two elbows
together. If you must elbow right away, do it as far
away from the hood’s exhaust opening as possible.
Distances over 30” are at the installer and users
discretion.
Cold weather installations
An additional back draft damper should be installed
to minimize backward cold air flow and a nonmetal-
lic thermal break should be installed to minimize
conduction of outside temperatures as part of the
vent system. The damper should be on the cold air
side of the thermal break. The break should be as
close as possible to where the vent system enters
the heated portion of the house.

DO NOT terminate the ductwork in an attic or other
enclosed space.
●
DO NOT use 4” laundry-type wall caps.
●
Flexible-type ductwork is not recommended.
●
DO NOT obstruct the flow of combustion and ventila-
tion air.
