Seismic Restraint; 20-A. Wind Restraint - Schwank STS-JZ Installation & Owner's Manual

20. SEISMIC RESTRAINT - LATERAL AND LONGITUDINAL
In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seis-
mic restraints. If the heater location can be impacted by wind (aircraft hangars, etc) refer to
High Wind Restraint section 11-B below. NOTE: Any suspension / restraint system must
allow for expansion of the tube and reflector system during operation.
Any and all required seismic mounting hardware is field supplied by the installer. The restraint
systems illustrated below are suggested only and typical of suspension and attachment to the
heater. Other restraint methods or systems may be required by local or national codes, or
specified by project engineering. It is the installer's responsibility to confirm restraint require-
ments with local authority prior to proceeding with the installation of restraints. The attachment
of suspension hardware to the structure is as required by site structural conditions, installation
codes, and/or local engineering design requirements.
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).

20-A. HIGH WIND RESTRAINT - LATERAL, LONGITUDINAL, AND VERTICAL
In areas with wind conditions (aircraft hangers, etc) in addition to lateral and longitudinal re-
straint the heater must be restrained from vertical movement. Suspend the heater using 3/8"
threaded rod with 3" adjustment turnbuckle through a safety ring at each hanger location.
