INSTALLATION
Refer to Figure 1.
1. Decide upon desired location in central hallway.
2. Remove attic insulation from area where the Whole-House
Ventilator will be installed. Make sure the attic floor is free
of electrical wiring or plumbing pipes. There should be
approximately 36" of clearance between the top of ceiling
joists and the roof. This will prevent back pressure which
can reduce efficiency and increase noise level.
3. Using the template provided on the louver carton,
determine the desired location and orientation of the
louver. Drive a small nail up through the ceiling at one
corner of the template.
4. Locate nail from above. Using this point as a reference,
layout louver cutout.
