FOR BEST RESULTS
When installing the Exhaust Fan/Light in a new construction site,
install housing during the rough-in construction of the building. The
blower unit, reflector and grille should be installed after the finished

1. Use 4” round duct.
2. Plan duct run from discharge opening of fan to the outside. For
best fan performance, make duct run as short as possible and
use minimum number of elbows.
3. Use optional Broan ducting accessories as needed.
WIRING
Plan to run 120 VAC house wiring (with ground) from power source,
through wall switch, to junction box in housing. For separate control
of fan and light use an optional Broan switch.
