Important Do’s and Don’ts
DO check the incoming mains water pressure and fl ow rate are adequate. (The
preferred range of mains pressure is 2-3bar).
DO check that all plumbing and electrical connections are in accordance with
the labelling on the thermal store.
DO check and ensure the air pressure side of the expansion vessel is set at 1.0 bar (or
as specifi ed) - sealed heating system only.
DO ensure that if the BoilerMate BP is fi tted on a sealed primary (i.e. closed) system,
then the boiler is suitable (i.e. fi tted with an overheat thermostat)
DO adjust the ballvalve so that the water level in the appliance F & E cistern when the
system is cold is correct and does not overfl ow when the appliance is at maximum
temperature
DO turn down the servicing valve for the ballvalve in the F & E cistern, once the
system is fi nally fi lled, to the point where the warning/overfl ow pipe will cope with
the discharge arising from a ballvalve failure.
DO check that the F & E cistern is not more than 6m above the base of the BoilerMate
appliance.
DO make sure that there is adequate clearance above the appliance F & E cistern to
service the ballvalve.
DO ensure that the boiler thermostat is set to maximum for all boilers.
DO insulate any exposed pipework in the BoilerMate BP cupboard.
DO plumb the overfl ow/warning pipe (if fi tted) in a 20mm internal diameter pipe
material which is suitable for use with a heating F & E cistern, in accordance with
BS 5449 (such as copper) and ensure it has a continuous fall and discharges in a
conspicuous external position.
DO check that the primary system pressure does not exceed 2 bar when the whole
of the system is up to temperature.
DO check the pump settings. The boiler/heating pump should be set to give a
temperature difference across the fl ow and return of not more than 11°C or as
recommended by the manufacturers.
DO ensure that the bypass valve for the heating system is set correctly.
DON’T use a combined feed and vent on BoilerMate BP installations.
DON’T place any clothing or other combustible materials against or on top of this
appliance.
No annual servicing of the BoilerMate BP is
necessary.
Free of charge replacements for any faulty
components are available from Gledhill during
the in-warranty period (normally 12 months).
After this, spares can be obtained direct from
Gledhill using the ‘Speed Spares’ service, or
through any of the larger plumbers merchants/
specialist heating spares suppliers.
Help and advice is also available from the
Technical Helpline on 0906 611 0005. Please
note this is a premium rate line and will be
charged accordingly.
However, all components are readily accessible
and can be changed quickly and easily by the
installer using common plumbing practice.
