SEISMIC RESTRIANT SUSPENSION METHODS
For standard seismic restraint such as earthquake prone
areas, install seismic restraint chain or cable as shown
below. If high winds can be encountered in the building,
such as found in airplane hangers where opposing doors
are simultaneously open, or system is installed near or
below the door opening, additional support of the radiant
tube and reflector network will be required. See the
“
Seismic Suspension For High Wind Applications ” below
for details. If there are any questions regarding what
method is best suited for your application consult your
sales representative or contact the factory. If the system
is a straight system (no elbows or tee's), apply an anti
sway chain or wire rope which is parallel to the radiant
tube at approximately the middle of the run.
Install the cable clamp
approximately 3” from
the edge of the reflector.
Clamp tight to prevent
chains or cables from
sliding on hanger

SEISMIC RESTRAINT FOR HIGH WIND APPLICATIONS
In high wind conditions it is recommended that
seismic restraints and reflector retention wire be
installed. See details below for recommended
installation of seismic restraint and anti sway
retention chains (wire rope). The vertical threaded
rod shall be attached and suspend the reflector
hangers at intervals of eight to ten feet (8' - 10'). At
least one vertical threaded rod shall be placed at
every elbow and/or tee connection. The threaded
rod is used to prevent the system from lifting during high
wind conditions, the chain or wire rope will keep the
system from swaying from side to side. When connecting
threaded rod to "Z" purlin use beam clamp or drill a hole
through "Z" purlin and secure with two 3/8" nuts and a lock
washer. If the system is a straight system (no elbows or
tee's), apply an anti sway chain or wire rope which is
parallel to the radiant tube at approximately the middle of
the run.
Punch or drill a small hole (approximately 1/8”) in the reflector near the
reflector hanger. Insert an appropriate length of 14 Ga. galvanized wire
through this hole and encircle the combination hanger. Maintain a loose loop
around the hanger, this will allow for expansion of the system. Twist the ends
of the wire together and trim as required. This retention wire may be installed
on both sides, or edges of the reflector for severe wind conditions.
