GRAVITY FED SHOWERS
The shower valve
must
be fed from a
cold water storage tank and a hot water
cylinder. The use of a Surrey or Essex
flange connection to the hot water
cylinder will ensure an independent
supply of hot water to the valve; this
action will stop air being drawn into the
system.
N.B. Keep all pipework runs as short as
possible for maximum shower
performance.
N.B. Wherever possible 22mm
pipework should be used.
GAS HEATED/COMBI-BOILER
SHOWERS
The shower valve must be installed with a
modulating type combi-boiler or multi-
point gas water heater. This system will
produce a constant flow of water within
the operating specifications of the
appliance.
N.B. The outlet temperature of the system
must
be capable of supplying hot water
in
excess of 60°C.
A pressure reducing valve may be
required to ensure that cold water
pressures do not exceed 4 Bar static.
