If the fan is stored for any length
of time prior to installation, store it
in its original shipping crate and
protect it from dust, debris and the
weather.
Installation
If the fan was delivered with the
motor unmounted, see the mainte-
nance sections for belt and pulley
installation.
If the fan was purchased as a wall
mount unit and a grease terminator or grease trough was
not purchased, a 1-1/16 inch diameter drain hole should be
inserted on the bottom side of the unit for drainage.
Fan Installation
a. Ensure the fan discharge is a minimum 40 inches
above the roof surface and a minimum of 10 foot from any
building air intake in order to comply with NFPA 96.

as well as the attachment of roof curbs to the building
structure must exceed the structural requirements
based on the environmental loading derived from the
applicable building code for the site. The local code

code based on local data. The licensed engineer of
record will be responsible for prescribing the correct
attachment based on construction materials, code
requirements and environmental effects specific to
