and are so marked.

F. The standard heaters are approved for
installations between 0 - 2000ft (0 - 610m)
for the US and 0 - 4500 ft (1370m) for
Canada. Conversion kits are available for

H. Massachusetts Requirement: If the heater
is being installed in the Commonwealth of
Massachusetts, this unit must be installed
by a licensed plumber or licenced gas fitter.
1.2 Heater Suspension
Attachment to the heater support lugs should
be made by D shackle. The hanging
attachments to overhead steelwork etc. must
be purpose made to sound engineering
practice or supplied to others. They must be
adequately fixed and designed to carry the
whole weight of the heater. In the event of
suitable roof steelwork being unavailable,
additional steelwork should be fitted to enable
vertical hangers to be used for suspending the
heaters.
These methods are illustrated in Figure 1. If
there are any doubts as to the strength or
suitability of roof steelwork to which heaters are
to be suspended, please refer to a Consultant,
Architect or owner of the building.
It is recommended that the heater is raised to its
final position once the assembly of the tube/
bracket/reflector has been completed. Longer
tube assemblies may be raised in more than
one sub-assembly with final tube connection
made in the air.
Ensure that the installer uses the burner roof
support mounting bracket when suspending the
heater. This is situated on the front of the
burner. When packed the bracket is reversed
and must be turned to its correct state for
mounting. (ref page 15)
