The BoilerMate acts as the
neutral point of the system
and therefore the cold feed
and open vent must be piped
to the appropriate connections
on the BoilerMate.
A draining tap conforming to
he overflow/warning pipe
The sealed central heating system
the current issue of BS 2879,
must be provided at the
lowest point of the system,
which will allow the entire
central heating and hot water
system to be drained.
T
should be in 20mm internal
diameter pipe of suitable
material for use in heating
systems in accordance with
BS 5449 (such as copper). It
should have continuous fall
and discharge in a conspicuous external position. It should not have any other pipework directly branched
into it.

3.5.4. Gledhill SysteMate Heating System
The Gledhill Boiler is also suitable for
use with a Gledhill SysteMate; an
integrated sealed heating system
and mains pressure hot water
appliance The SysteMate uses an
indirectly heated open vented hot
water only primary store. The central
heating circuit is suitable for sealed
heating systems as shown
schematically in diagram 3.8. For
further details refer to Gledhill
SysteMate manual.
When using the boiler with a
SysteMate, the pressure safety valve
must be fitted on the boiler flow pipe
adjacent to the boiler. The expansion
vessel should be fitted adjacent to
the SysteMate and connected to the
connector on the SysteMate.
design and component selection and
sizing including filling arrangements
should follow the guidelines
discussed in section 3.5.2 ‘Sealed Heating Systems’.

above the BoilerMate should not be greater than 10m.
