Pipework connections
The position of the pipework connections is
shown opposite . The connection sizes and
dimensions are listed in Section 1.2 Technical
Data.
All the connections are also labelled on the
appliance. It is essential that the pipework is
connected to the correct connection.
The connections can be hard piped but we
recommend the use of flexible connections
(available as an optional extra).
When using the push fit connectors with the
flexible hose kits it is important to check that
they are compatible. Written approval has
already been obtained for :-
Hepworth - Hep O BiTite
2
John Guest - Speedfit
Yorkshire - Tectite
However, as similar assurances cannot be
obtained for Polypipe fittings we cannot
recommend their use at this time.
Connections :-
A. Primary flow (from boiler)
B. Primary return (to boiler)
C. Central heating flow
D. Central heating return
E. Drain assembly
F. Incoming mains water
G. Balanced pressure cold outlet
H. Domestic hot water
I. Discharge from the ERV
J. Discharge from the P & T valve
Ensure the discharge pipes from the P & T valve
and ERV are laid to a continuous fall and that
there is at least 300mm of vertical pipework
below the tundish before any bends.
