for air and where possible, the system pipe
work should have a gradient to ensure any
excess air is carried naturally to other purpose
made, air release points.
5.8 The system's water must always be
allowed to circulate whenever the circulation
pump is running. A return by-pass must be
provided.
NOTE – It is no longer permissible to use
non-thermostatic radiator valves to allow
by-pass through a radiator.
5.9 In high water volume systems or under
floor heating
operation of the boiler is expected at
temperatures below 60
installed on the boiler outlet in order to
prevent condensation forming inside the boiler
body. Failure to comply with this requirement
will invalidate the manufacturer's guarantee.
5.10 The pressure relief discharge must be
directed away from any electrical equipment
or where it could cause a hazardous situation

and terminated in a safe but visible position.
5.11 To enable adequate drainage of the
system drain cocks compliant with BS2879
must be fitted at the lowest points in the
system pipe-work.
5.12 To obtain the best hot water performance
from your boiler it is suggested that the cold
water supply to the boiler is taken directly
from the incoming mains water supply.
Note that the boiler will not operate unless
there is a minimum pressure of 0.25bar with a
flow rate of 2.5l/min. Where inlet pressures
exceed 8bar, a pressure regulator must be
fitted to the cold water supply.
5.13 Where cold water mains are fitted with a
water meter, check valve(s) or loose jumper
stopcock it is recommended that a domestic
hot water mini-expansion vessel may need to
be fitted.

5.14 Although the boiler is designed to inhibit the
formation of scale, in hard water areas above
200mg/l, a proprietary scale reduced should be
fitted in the cold water supply to the boiler.
5.15 To obtain the best hot water performance
from your boiler it is suggested that supplies to
faucets are run in 15mm copper, as short as
possible and where practical, be insulated to
reduce heat loss.
5.16 The boiler incorporates a frost protection
thermostat. Therefore if the boiler will not be
used for long periods of time during cold weather,
in order to avoid freezing the electric supply must
be left ON and all the central heating isolation
valves must be left open.
thermostat will then operate the boiler if the
temperature falls too low.
electrical supply is to be turned off the boiler, the
heating system and domestic hot water circuit
must be drained.
6. Appliance Sitting
6.1 If the boiler is to be installed in any room or
compartment, it requires no purpose made
ventilation for combustion air. If sited in a room
containing a bath or shower then particular
reference is drawn to the current I.E.E. Wiring
Regulations and local Building Regulations.
.
6.2 The boiler is not suitable for external
installation unless protected by a purpose made
building such as a boiler house.
6.3. The following clearances are recommended
for installation purposes; 200mm above, 300mm
below and 20mm at each side. 600mm is required
at the front but this may be upon opening a
cupboard door.
6.4 The boiler must be sited at least 1m away from
flammable materials and combustible walls must
be protected with appropriate insulation.
.
6.5 The wall on which the boiler is mounted must
be sufficiently strong enough to support the
weight of the boiler.
