Seismic Restraint - Schwank SPW2-JZ Series Installation & Owner's Manual

8-A. SEISMIC RESTRAINT - LATERAL AND LONGITUDINAL
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 (aircraft
hangars, etc) refer to High Wind Restraint section 8-B.
These restraint systems indicate suspension of and attachment to the heater. The attachment
of suspension hardware to the structure will be as required by site structural conditions, instal-
lation codes, and/or local engineering design requirements. Other types or systems of restraint
may be specified by local or national codes, or by project engineering design specifications.
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.
