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

G.
Massachusetts Requirement:

a licensed plumber or licenced gas fitter.
Note: Any outdoor installations must be
installed with a vent cap at the inlet and
the flue end.
1.2 Heater
Suspension
Attachment to the heater support lugs should
be made by D shackle. The hanging
attachments to overhead steelwork etc. have to
be designed and produced in accordance with
sound engineering practices. 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 emitter
tube/bracket/reflector has been completed.
Longer tube assemblies may be raised in more
than one sub-assembly with final emitter 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 22.)
WARNING:
If not installed, operated and maintained in accordance with the manufacturer’s
instructions, this product could expose you to substances in fuel or from fuel combustion
which are known to the state of California to cause cancer, birth defects or other
