SUSPENSION METHODS
WARNING
COLLAPSE, FIRE AND EXPLOSION HAZARD
Improper suspension of the tube heater may result in
collapse and being crushed. Always suspend from a
permanent and secure part of the building structure
that can evenly support the total force and weight of
entire the heating system.
Failure to suspend properly and maintain minimum
clearance to combustibles may result in death,
serious injury, fire and/or explosion or property
damage. Always maintain minimum clearances and
post clearance signs where needed.
Radiant tube and reflector system shall be suspended by
chain (trade size #3 or larger), wire rope, etc., minimum
workload of 90 Lbs. All suspension hardware must be
corrosion resistant. For fine adjustment turnbuckles may be
used.
NOTES
:
SUSPEND IN VERTICAL FASHION WHEN INITIALLY
INSTALLED (BURNER NOT FIRING).
Suspend the burner assembly with 1/0 closed loop chain
or greater – minimum working load of 200 lbs. Radiant
tube and reflector system is to be suspended with trade
size #3 chain or heavier – working load of 90 lbs.
minimum. A minimum of 12" (30 cm) of hanging chain is
recommended. This allows for system expansion and
contraction, reducing the likelihood of reflector and radiant
tube warping and/or expansion noise.
CAUTION: Infrared tube systems expand and contract
upon each call for heat. System expansion of up to 3” can
be expected.
Provisions must be made to limit lateral movement when
systems are installed in site conditions where open doors
may create a wind condition – see page 12 for guidelines.
Radiant tubes DO NOT require sloping.
For fine adjustment turnbuckles may be used.
NOTES
:
•
SECURE TURNBUCKLES SO THAT THEY WILL NOT
UNWIND OR UN-SCREW.
•
CRIMP "S" HOOKS CLOSED BEFORE LEAVING
JOB. REFLECTORS ARE NOT TO BE INSTALLED
ON TOP OF COMBINATION HANGERS.
