CaptiveAire HVLS - Installing Fan between OWSJ

18
Installing Fan Between OWSJ
If installing the fan between OWSJ, the fan must be mounted to angle iron. Verify the distance between the
joists. If the distance is 10 feet or less, use kit HVLS-MOUNT-OWSJ-10. If the distance is greater than 10
feet and less than 18 feet, use kit HVLS-MOUNT-OWSJ-18. The distance between the joists must not
exceed a maximum distance of 18 feet.
The angle iron actual sizing is 11’-6” for 10-foot sections and 19’-6” for 18-foot sections. This allows for a
minimum of 9” overhang past each joist. If the angle iron is cut down to fit the distance between the joists,
the minimum 9” overhang on each joist must remain.
Keep the fan’s weight distributed away from the joist. Install the fan at least 1/4 distance away from the
edge of the mounts, refer to Figure 15.
