PLANNING INSTALLATION
When installing the ventilation fan in a new construction site, install the main body of the fan and ductwork
during the rough-in construction of the building. The grille should be installed after the finished ceiling is in
place. Use the dimensions provided in this manual to determine the required hole size for the ceiling.
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 specified in this manual. Insulation around the ducts can reduce energy loss and
inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow. Do not install the
ventilation fan in areas where the ductwork will require configurations as shown in Fig. 1 below.
Recommended installation includes insulating around ductwork and the fan housing to minimize heat loss (see
Fig. 2 above). Seal all gaps around the housing with caulk or other similar material to inhibit air leakage to the
exterior of the thermal envelope of the building. Rigid sheet metal duct and the shortest path to the outside
will minimize static pressure losses and promote adequate air flow.
