All components included in these unit ventilators are designed,
manufactured and independently tested, rated and certified to meet
the seismic compliance standards of the International Building
Code.
•
Components designated for use in systems that are life safety,
toxic, high hazard, combustible or flammable meet the on line,
anchorage and load path requirements for life safety as defined in
IBC sections 1621.1.6, 1621.3.3,1707.7.2. and IBC Commentary,
Volume II, section 1621.1.6, IBC notes pertaining to the release of
