Properly insulate the area around the fan to
minimize building heat loss and gain. (Fig.18)
Loose fill or batt insulation can be placed
directly over the fan housing in the attic.
Our fans and fan/light combination units do
not create excessive heat that is a common
problem with recessed light fixtures or some
competitor’s fan/light combination. Our
efficient, cool-running motors and our
fluorescent lamps do not create enough
ambient heat to be subjected to these
limitations. The ducting from this fan to the
outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use
the shortest, straightest duct routing possible for best performance, and avoid installing the fan
with smaller ducts than recommended. Insulatin around the ducts can reduce energy loss and
inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.
PRACTICAL GUIDE TO INSTALLATION

3 inch or 4 inch roof jack, wall cap,
or soffit vent with backdraft damper
Mechanically connect duct to termination
and seal with mastic or approved foil
faced tape
2-3 ft straight run before elbow
In attic installation,
caulk box to drywall
A short piece of flexible duct helps
alignment and absorbs sound.
Use clamps plus mastic or approved
foil faced tape at all flex joints.
Foil tape tightly covers all metal
duct joints. (Glue PVC joints)
