2.0 INSTALLATION
All factory made joints should be checked after installation in case they have
been loosened during transit.
OV Model
The fittings for the feed and expansion cistern should be installed and the cistern fitted
on top of the appliance/on its supports.
The 22mm safety/open vent shall rise continuously from the boiler and terminate in
the F & E Cistern.
The 15mm cold feed/expansion shall be connected from the F & E Cistern to the
connection provided on the top of the appliance.
No valves should be fitted in the safety open vent which must be a minimum of 22mm
copper pipe or equivalent.
The overflow/warning pipe shall have a continuous fall, be fitted to discharge clear of
the building and be sited so that any overflow can be easily observed. It shall also be
installed in a size and material suitable for use with heating feed and expansion cisterns
in accordance with BS 5449 and should not have any other connections to it.
SS Model
The expansion vesel should be fitted on top of the appliance/supports provided and
connected to the appliance using a manual air vent at the high point.
It is normally envisaged that the feed and expansion cistern/expansion vessel will be
located in the same cupboard as the Accolade 2000 appliance. In the case of the OV
model this will allow a dry roof space.
However, if it is necessary to locate the cistern in the roof space any pipework in the
roof space and the feed and expansion cistern will need to be adequately insulated
to protect against frost damage.
