INSTALLATION CONSIDERATIONS
ROOF SLOPE
NOTE:
For roof angles in excess of 20°, consult factory. The extension
lengths shown are minimum recommendations only, based
solely o roof pitch and fan diameter. Other considerations
must be evaluated when determining extension requirements,
such as placement of lights, sprinkler systems, HVAC
systems, etc. In addition, OSHA requirements state that fan
blades must be a minimum of 10' above the oor.
NOTE:
All fan blade parts must be greater
than 3' from all obstructions
including lights, cables, sprinklers
and other building components and
greater than one (1) fan diameter
from any wall to blade tip.
Failure to maintain exclusion
zones outlined on pages 7,
8 and 9 could result in fan
failures, including blade
separation, which could result
in death or serious injury.
DO NOT operate fans when
physical obstructions or HVAC
air ows extend into exclusion
zones. Regularly inspect fans
to ensure exclusion zones
remain clear of interference
before operating fan.
*Consult factory for assistance with fan placement and extension selection.
