4 Cobra herringbone gas
radiant tube heaters
For herringbone heaters refer to the
relevant information leaflet
(GB/HB/134/0402).
A herringbone system allows several
Cobra heaters to be operated by one
combustion fan. This has the benefit of
only one building penetration being
required when flueing the products of
combustion.
5 Health & safety
Ambi-Rad Limited cannot be responsible
for ensuring that all site safety
procedures are adhered to during
assembly and installation. Sole liability
rests with the installer.
6 Installation - suggested
methods of heater
suspension
Attachment to the heater support lugs
should be made by either a ‘speed link’, D
shackle, nut bolt and large washer, 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, unpacked
152kg.
In the event of suitable roof steelwork not
being available, additional steelwork
should be fitted to enable vertical hangers
to be used for suspending the heaters.
If there are any doubts as to the strength
or suitability of roof steelwork to which
heaters are to be suspended, please refer
to consultant / architect / owner of the
building.
