Z-Purlin Mounting Kit
IMPORTANT:
Structural Engineer of Record (SEOR)
must perform thorough evaluation of mounting structure
and determine final mounting requirements before fan
is installed. Manufacturer is not liable for any problems
that arise as the result of insufficient structure, including
(but not limited to) vibration, noise, or safety hazards.
Product warranty will be voided at manufacturer’s
discretion if structure is deemed insufficient.
Installations must comply with the following
requirements at a minimum, but SEOR may require
more stringent specifications at their discretion:
Do not install HVLS fans on a single z-purlin.
Structural steel angles must be used to span a
minimum of 2 z-purlins.
Z-purlins must have a minimum flange width of
2 inch and a minimum material thickness of 12
gauge steel.
Structural steel angle span lengths must not
exceed 8 feet. For span lengths up to 8 feet, a
minimum of 2 structural steel angles are required.
Size of structural steel angles must be specified by
a structural engineer. Angles must be a minimum
of 4 x 4 x 1/4 inch thick. Larger angles may be
required for span lengths up to 8 feet. Angles shall
be sufficiently stiff to avoid harmonic resonance
excitation during fan operation (120 RPM;
+/- 20%).
