TYPICAL SUSPENSION METHODS 

Not  with  standing  their  limited  scope,  the  appliance  should  be  installed  in  accordance  with  the  relevant 
provisions of any National  Gas Safety (Installation and  Use) Regulations. Due account should also be taken  of 
any obligations arising  from any National  Health  and Safety at Work Regulations, National and Local Building 
Regulations and National Electrical Wiring Regulations. The appliance must be installed, and where necessary, 
converted for use on other gases, by a qualified installer. 

 

Various means of suspending the heater can be used. See the following drawings for typical examples. 

a.

 

Use only noncombustible materials for suspending hangers and brackets. 

b.

 

Linear Tube Heaters should be suspended to provide a slope of 0.25 degree up to the fan (25 to 50mm). The 
appliance should be located with respect to building construction and other equipment to permit access to 
the appliance for servicing etc. 

c.

 

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. 

d.

 

For suspending the appliance it is recommended that suitable protected welded chain (Ø 3mm x 65 links 
per m) or Ø 8mm min mild steel drop rods and suitable brackets are used. Attach the chains or drop rods to 
the  hanger  brackets  where  shown  providing  at  least  Ø  5mm  closed  link  hooks  are  used  chains  may  be 
attached directly to the hanger brackets. 

e.

 

Heaters subject to vibration must be provided with vibration isolating hangers. 

f.

 

Heaters must not be  supported by gas or electric supply lines and must be suspended from a  permanent 
structure with adequate load capacity. 

g.

 

Hanging points are fixed along the length of heater to accommodate trim pieces. Secondary steel work may 
be required to span between supporting beams. 

h.

 

The appliance should be located with respect to building construction and other equipment to permit access 
to the appliance for servicing etc. 

Space-Ray 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  914  mm  to  minimize  any  vibration  that  might  be  generated  by  the  draft  inducer 
assembly.  If  these chains  must  be  less  than  914  mm,  then  do  not  use  the trapeze  method  and,  instead,  use 
individual chains on each tube support/hanger bracket.
