Instructions / Assembly

Whatever the case, insert the completed inlet line into the
access hole and thread it down inside the wall. The inlet
line should be long enough so that it extends above the
joists in the attic; at this height, it can be easily
connected to the branch and truck lines. When cutting
the inlet tubing to length, remember that your inlet will be
placed at 18” above the floor.
For a basement installation, assemble the tubing to the
inlet flexible tubing in the same way and insert it into the
access hole. A basement inlet line is necessarily shorter
because it must only reach 18” from the floor to the inlet.
Most of the time, Basement inlet lines are more easily
installed by two
people after the
inlet hole has been
cut in the interior
wall. See “Wall Inlet
Installation.”
Complete all your
inlet lines, and then
proceed to your
inlet installations.
WALL INLET INSTALLATION
The wall inlet design allows you to work outside the wall
—where assembly is easy and all the parts you need are
accessible. First, you make a cutout into the wall and
locate the flexible tubing attached to the inlet line which
you previously threaded into the wall. Then, you attach
the flexible tubing to the inlet mounting plate, assemble
the other inlet parts, and make the wiring connections.
You place the inlet assembly into the wall cutout,
sandwiching the wall between the inner and outer parts,
and secure the inlet tightly to the wall with two screws.
Assemble and install the wall inlet as shown in the
illustrations and as explained in the next few pages.
Be careful and patient as you make your first cutout and
install your first inlet by following the procedure step by
step —the other inlets will be easy to install in very little time.
Making the Wall Inlet Cutout
The wall inlet should be
located 18” on-center
from the floor and
directly in line with the
attic or basement inlet
tubing hole you have
already drilled in the
wall plate or header. the
wall inlet cutout must be
exactly 3
7
⁄8” high by
2
7
⁄8” wide. It is crucial
that you make an
accurate cutout, and we
have supplied a
template to help you.
Place the template against the wall so that it is 18”
on-center from the floor. Use a level along the top edge of
the template to make sure it is square to the wall. Mark
your wall for the
cutout by tracing
around the inside of
the template. Then
use your pencil to
mark the screw hole
locations through
punched holes at the
top and bottom of the
template. Remove
the template from
the wall.
