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 suspending hangers and brackets.
2.
A minimum No. 2 chain with a working load limit of 115 lbs. is required.
3.
Turnbuckles can 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.
Mestek, Inc. recommends that the body sections be suspended using chains with turnbuckles. This will allow
slight adjustments after assembly and heater expansion/ contraction during operation.
If a “trapeze” method is used for tube support/hanger brackets (shown below), the minimum chain length for the
two connecting chains is 36” to minimize any vibration that might be generated by the burner box. 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.
