FOR BEST RESULTS

In a new construction site, install the housing (complete
with heater) during rough-in construction of the building. The
light assembly and the grille should be installed when the
finished ceiling is in place.

Installation in an existing, finished building requires an
accessible area (attic or crawl space) above the planned
location. See “INSTALLATION IN EXISTING
CONSTRUCTION.”

Do not install closer than 12 inches to a vertical surface.
Do not install over tub or shower enclosure.

For installation in sloped ceilings up to 12/12 pitch.

•

Ductwork must point up.

UNIT DIMENSIONS
