SUSPENSION
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 maintain minimum clearance to
combustibles may result in fire and/or explosion,
property damage, serious injury or death. Always
maintain minimum clearances and post clearance
signs where needed.
Combustion Research Corporation recommends that
Omega II
®
systems are hung by means of chain. Chain
and “S” hooks are supplied as an option. DO NOT
STRETCH OR INSTALL CHAIN OTHER THAN IN A
VERTICAL FASHION WHEN INITIALLY INSTALLED
(BURNER NOT FIRING).
If chain is not supplied by Combustion Research Corp.,
furnish a chain with a minimum 90 lb. workload (trade size
#3 or larger). 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 4” 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 8 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.
