INSTALLATION IN EXISTING CONSTRUCTION
Installing the ventilator in an existing house requires an accessible
area (attic crawl space) above the planned installation location.
Review “INSTALLATION IN A NEW CONSTRUCTION” and follow all
instructions which apply to your installation.
Location – locate ventilator parallel to a ceiling joist.
Wiring and Ducting – plan ducting and wiring before proceeding with
installation.
Refer to Figure 2 for wiring and Figure 1 for ducting.
CAUTION: Check area above planned installation to
be sure that:
1. Ducting can be installed.
2. Wiring can be run to the planned location.
3. No wiring or other obstructions might interfere with installation.
INSTALLATION FROM ACCESSIBLE
AREA ABOVE
1. From below, drill a small hole in ceiling at the planned location.
Stick clothes hanger through hole to help locate it.
2. Locate hole in attic or crawl space.
3. In attic or crawl space, mark ceiling for cutout by using the housing as
a template. The long side of cutout must be parallel
to ceiling joist.
4. Make cutout along marked line.
