2.2 Heater Mounting
The heater and flue must be adequately
supported by one of the following methods ;
a) Suspension by steel drop rods or
straps from the M10 fixing points
located on top of the heater.
These must be of sufficient strength to
safely carry the weight of the unit and
ancillary equipment. The straps may only
drop vertically to eyebolts, if used; I.E. They
must not be joined to the eyebolt at an angle
to the vertical, and eyebolts if used should
be of an approved type.
b) VRA heaters can be mounted on
specifically designed cantilever wall or
vertical stanchion brackets which
locate directly to the four M10 fixings
on the heater casing.
Alternatively VRA or VRC units can be
mounted on cantilever type wall brackets
however consideration must be given to
ensure that the bracket is large enough to
support the heater whilst providing the
necessary clearances
In either case the installer should ensure
that the wall wall fixings or other support
medium is capable of supporting the weight
c) On a level non-combustible surface
capable of adequately supporting the
weight of the unit and ancillary
equipment .
