10-A SEISMIC RESTRAINT - LATERAL AND LONGITUDINAL PLANES
In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seis-
mic restraints as indicated in Figure 11. If the heater location can be impacted by wind (near
overhead doors, aircraft hangars, etc) refer to High Wind Restraint section
10-B
below.
These instructions indicate attachment of suspension and restraint hardware to the heater. The
attachment of suspension hardware to the structure will be as required by site structural condi-
tions, installation codes, and/or local engineering specifications. Other types or systems of re-
straint that are specified by local or national codes, or by project engineering design specifica-
tions may be used .
Schwank / InfraSave offers optional items: #2 Lion Chain 115 lb work load x 200 ft roll (PN: JL-
0800-XX); and Safety Snap Hooks (PN: JL-0800-SH = pkg 24; JL-0800-SH-B = pkg 100).
All other required seismic mounting hardware is field supplied by the installer.
10-B HIGH WIND RESTRAINT - LONGITUDINAL, LATERAL, AND VERTICAL PLANES
In areas with wind conditions that can impact the heater (outdoor, aircraft hangers, etc): in ad-
dition to lateral and longi-
tudinal restraint the
heater must be re-
strained from vertical
movement.
Suspend the heater
using 3/8” threaded
rod with 3” adjust-
ment turnbuckle at
each hanger location
to restrain up-and-
down movement.
Install angled chains
for lateral and longi-
tudinal restraint.
