INSTALLATION IN
EXISTING CONSTRUCTION
In an existing, finished building, installation of the Heat-
Vent-Light Combination requires an accessible area (attic or
crawl space) above the planned location. If the location that
has been chosen for installation has a finished floor above it,
be certain there is sufficient space available to install the
housing and make the necessary duct connection.
PLANNING

follow all instructions that apply.
CAUTION: Check the area above the planned location
to make 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
the installation.
