MOUNTING
STEP 3 (Wall and Surface Mounting)
If installing the unit onto a cabinet, wall, wood
header, rim joist, or mesh on an existing crawl
space vent, please use the unit or plastic
template to determine the mounting location.
Secure the mounting frame onto the surface
with the included wood screws. If using a
machine screw with nuts, you may need to drill
a hole. Note that models T8 and T8-N do not
include a plastic template.
STEP 3 (Foundation Block Mounting)
To install the unit onto a foundation brick or
block, mark the mounting hole locations using
the four corners of the metal face plate. Then
drill 5/16" holes with a drill bit. Install wall
anchors into openings and secure the unit into
the wall with four screws. Note that the models
T3 and T7 are designed for cabinet and wall
mounting, and do not include wall anchors and
larger type screws.
