Instantaneous Gas-heated Systems,
e.g. combination boilers (
The mixer shower MUST be installed with a
multi-point gas water heater or combination
boiler of a fully modulating design i.e. to
maintain relatively stable hot water temperatures.
A drop tight pressure reducing valve MUST
be fitted if the supply pressures exceed 5 bar
running.
An expansion vessel MAY be fitted and regularly
maintained, to prevent the mixer shower
being damaged by excess pressures. This may
already be installed within the boiler (check with
manufacturer) and is in addition to the normally
larger central heating expansion vessel.
Unvented Mains Pressure Systems (
The mixer shower can be installed with an
unvented, stored hot water cylinder.
For systems with no cold water take off after the
appliance reducing valve, it will be necessary to
fit an additional drop tight pressure reducing
valve when the mains pressure is over 5 bar. The
drop tight pressure reducing valve must be set at
the same value as the unvented package pressure
reducing valve.
NOTE: An additional expansion vessel may be
required if a second pressure reducing valve is
installed. This does not apply to packages with
a cold take off after the pressure reducing
valve to the cylinder.
