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
