accommodate the Accolade Estate is
700mm.
The base chosen for the cylinder should be
level and capable of supporting the weight
of the unit when full of water as shown in
General Data. The discharge pipework for the
safety valves must have a minimum fall of 1 :
00 from the unit to a safe discharge point. All
exposed pipework should be insulated and the
600 mm
unit should NOT be fixed in a location where
minimum
the contents could freeze.

There should be no valves or other
mm
equipment in the pipe connecting the
boiler flow to the appliance.
MAINS WATER SUPPLY
Existing properties with a 15mm supply will be
satisfactory provided the local mains pressure
is good, but should be confined to single
bathroom properties. For new properties
where simultaneous demand is required to
more than one bathroom or a bathroom and
one or more en-suites, the communication
and service pipe into the dwelling should
be a minimum of mm (usually in the form
of a 5mm MDPE supply). The minimum
recommended static pressure to operate an
Accolade Estate domestic system is bar.
There should be a flow of at least 5 litres per
minute or above available into the property.
Normally Accolade Estate provides well in
excess of 30 litres/min in most conditions.
Flow rates for ALL mains pressure systems
are subject to district pressures and system
dynamic loss.
GENERAL RESTRICTIONS
a. The highest hot or cold water draw off
point should not exceed 4 metres above
the Pressure Reducing Valve.
b. An ascending spray type bidet or any other
appliance with a Class 1 back-syphonage
risk requiring a type A air gap should not
be used.
c. Accolade Estate should not be used where
steam is the primary heating medium, or in
a situation where maintenance is likely to
be neglected.
d. Unvented cylinders are not suitable for use
with solid fuel boilers.
