9.0) TYPICAL SUSPENSION METHODS
SUSPENSION HAZARD
Burner must be secured to the mounting flange with nuts.
All materials used to suspend the heater must have a minimum working load of 115 lbs.
All “S” Hooks must be crimped closed.
Never use the heater to support a ladder or other access equipment. Failure to do so may result in death, serious injury or property damage.
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 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.
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.
