INSTALLATION CONSIDERATIONS
ROOF SLOPE
NOTE:
For roof angles in excess of 20°, consult factory. The extension lengths shown are
minimum recommendations only, based solely of 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 center of fan.
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.
