Recommended Installation

With higher cfm hoods

Attaches on top of the hood in
the ductwork and via low voltage
wire “talks” to the make-up air
damper

more air is exhausted in
tighter homes with less air
coming back in. To “make
up” for lost air, the
Universal Make up Air kit
brings fresh outside air into
the home through a
separate fresh air duct. The
automatic damper opens
inside the duct to bring
in air when the hood is
operating above 400 cfm
and closes tightly when the
hood is off.

Opens when the
hood is on, closes
when the hood
is off

Note: The fresh air damper is installed into a completely separate duct independent of the range hood ducting. The ductwork and make­up air damper are linked into your return air side of the central HVAC system OR a separate duct coming from the outside directly into
the kitchen. The air flow switch and damper are linked thru low voltage wiring. The plug-in 24 volt transformer is required when installing
the fresh air duct and damper directly thru the kitchen wall. Connecting to the Central HVAC system does not require the transformer. A
qualified HVAC professional should inspect your home to determine the best installation.

WARNING! Product specifications are subject to change without notification. Consult the installation instructions before you begin installing this range hood.
