INSTALLATION
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. However, if
it is necessary, the cistern can be installed in the roof space.
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 BP 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.
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 Overfl ow 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.
