Our Commitment
Typical Installation
The ducting from this fan to the outside of the building has a strong effect on the airflow, 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. Insulation around
the ducts can reduce energy loss and inhibit mold
growth. Fans installed with existing ducts may not
achieve their rated airflow.
Rigid metal duct is recommended for optimal fan
performance.
Ensure duct joints and exterior penetrations are
sealed with caulk or other similar material to create
an air-tight path and to minimize building heat loss
and gain and reduce the potential for condensation.
Place/wrap insulation around duct and/or fan to in
order to minimize possible condensation buildup
within the duct, as well as minimize building heat
loss and gain.
