INSTALLATION
NOTE: For maximum operating efficiency, the proper intake air opening must be provided to allow replacement of exhaust air. The best
location for air intake is at the opposite end of the attic. See “Attic Intake Air Required” section.
1. This gable ventilator is designed to mount behind existing louvers in your attic. If a louver is not present and one must be installed, it
should be mounted in the center of the upper most portion of the gable. The area of the louver should be greater than the outlet area of the
ventilator.
2. There are four sets of holes spaced 90º apart in the housing, providing a choice of four depth positions. Reversing the brackets makes
eight positions. Select the proper mounting holes to align the bracket and mounting structure on louvers.
3. Figure 1 shows the ventilator mounted directly against a gable louver. If the louver is sufficiently strong, the mounting brackets may be
nailed or screwed to it.
4. If mounting the vent directly to the gable louvers is undesirable, a pair of furring strips may be suspended vertically a minimum of 14 3/4
inches apart.
5. Figure 2 shows the ventilator mounted on a rectangular louver.
6. For better performance: Cover any open louvered area around vent with plywood or other suitable material. This will improve the efficiency
of the air exchange between the attic and the outside. It will also prevent the thermostat from being directly affected by outside air.

MINIMUM ATTIC INTAKE AREA REQUIRED
Sufficient intake area must be provided in the attic to assure that the fan will not be overloaded and that it will deliver its rated CFM. This can
be accomplished with some type of attic venting such as gable louvers or under-eave vents. The table below shows the minimum intake area
needed for each fan installed.
