Installation Procedure
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. Insulation around the ducts can
reduce energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated airflow.

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,
building heat loss and gain.
