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.
In no case should any support that
anchors only into drywall or other interior wall/ceiling facing be used for
installing this appliance.
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
