Typical Suspension Methods - Space-Ray LTU SERIES Installation And Operation Instructions Manual

15.2)

TYPICAL SUSPENSION METHODS

Various means of suspending the heater can be used. See the following drawings for typical examples.
1. Use only noncombustible materials for hangers and brackets.
2. A minimum No. 2 chain with a working load limit of 115 lbs. is required.
3. Turnbuckles should be used with chains to allow leveling of the heater. All "S" hooks and eye bolts must be manually
crimped closed by the installer.
4. When using rigid means for heater suspension (rod, flat bar, etc.) provide sufficient lengths or swing joints to compensate
for expansion. See Figures b and c.
5. Heaters subject to vibration must be provided with vibration isolating hangers.
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent structure with
adequate load capacity.
Space-Ray recommends that the body sections be hung by chains with turnbuckles. This will allow slight adjustments after
assembly and heater expansion/ contraction during operation.
If a "trapeze" method is used (shown below), the minimum chain length for the two connecting chains is 36". If these chains
must be less than 36", then do not use the trapeze method and, instead, use individual chains on each tube support/hanger
bracket.
