It is normally envisaged that the feed and
expansion cistern will be located in the same
cupboard as the BoilerMate appliance itself to
maintain a dry roof space.
The cold feed/open vent pipework assembly (as
supplied) is all that is required if it is intended
to install the F & E cistern directly on top of the
appliance
However, if it is necessary to locate the cistern
in the roof space (or on a higher floor) the
cold feed/open vent pipework assembly (as
supplied) should be used to connect to the
F & E cistern and pipework site run by the
installer to connect this to the appliance.
Note: When fi tting the cistern at a higher level
this must not be fi tted more than 6 metres
above the base of the BoilerMate A Class
appliance.
Obviously, if installed in the roof space the feed
and expansion cistern and any pipework will
need to be adequately insulated to protect
against frost damage.
Combined feed and open vent pipe
arrangements must not be used.
No valves should be fi tted in the safety open
vent which must be a minimum of 22mm
copper pipe or equivalent.
If the automatic fi ll version appliance is used the
overfl ow/warning pipe shall have a continuous
fall, be fi tted 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.
