HE Series Infrared Gas Heater Installation and Operation Manual
10 - A SUGGESTED SEISMIC RESTRAINT - Lateral and Longitudinal Planes
NOTE: Seismic restraint requirements vary greatly by geographic region or area. The infor-
mation below is a guideline only for suspension of the heater. Adhere to specific seismic re-
quirements and specifications of local engineering authority.
In areas prone to earthquake, or specified on a project, install lateral and longitudinal seismic
restraints as suggested in Figure 7. If the heater location can be impacted by wind (near over-
head doors, aircraft hangars, outdoors, etc) refer to High Wind Restraint section 10 - B below.
These guidelines 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 required .
All required seismic mounting hardware is field supplied by the installer according to local
specifications.
10 - B SUGGESTED HIGH WIND RESTRAINT: Lateral, Longitudinal, and Vertical Planes
In areas with wind conditions that can impact the heater (outdoor, aircraft hangers, etc): in ad-
dition to lateral and longitudinal restraint the heater should be restrained from vertical move-
ment (lift).
Suspend the heater us-
ing 3/8” threaded rod
with 3” adjustment turn-
buckle at each hanger
location to restrain up -
and - down movement.
Install angled chains for
lateral and longitudinal
restraint.
