1.3 Heater
Suspension
Attachment to the heater support lugs should be
made by a ‘speed link’, D shackle or in the case
of drop rods, a closed formed hook. The
hanging attachments to overhead steelwork
etc. must be purpose made to good sound
engineering practice or of a proprietary type
fixing. 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.
The suggested mounting heights for AmbiRad
heaters are given in table 1 below.
1.4 Wall
Mounting
These radiant tube heaters can be wall mounted
using the appropriate bracket.
When using the wall mounting brackets the
heater must be inclined at an angle between 35°
and 55°.
