SUSPENDING THE SYSTEM
WARNING
Inadequate or improper suspension of the tube heater can result in collapse of the
system, property damage, risk of fire/explosion, personal injury and/or death.
It is the
installer’s responsibility to ensure that the hardware and structural supports from which the
heater is suspended are sound and of adequate strength to support the weight and expansion
forces of the heater.
Consider that the heater will expand in length as much as ½ inch (12.7) or more for every 10 ft
(3 m) of system length. Typically, the greater the firing rate, the greater the expansion.
Survey the available structural supports, considering the system configuration and heat
requirements of the area to establish the optimum heater location. Locating a heater directly
under joists or beams, or installing supplemental steel support rail or angle iron can
substantially reduce labor and material requirements. Hardware with a minimum 60 lbs (27 kg)
workload must be used at each heater suspension point. Connect the structure using typical
hardware as illustrated below or by other mechanically sound means
.
