GENERAL
GAS SUPPLY
The local gas supplier should be consulted, at the installation
planning stage, in order to establish the availability of an adequate
supply of gas. An existing service pipe must NOT be used without
prior consultation with the local gas supplier.
The boiler is to be installed only on a gas supply with a governed
meter.
A gas meter can only be connected by the local gas supplier or by
a local regional contractor.
Check that the appliance is suitable for the proposed gas supply.
An existing meter should be checked, preferably by the gas supplier,
to ensure that the meter is adequate to deal with the rate of gas
supply required. A minimum gas pressure of
20 mbar MUST be available at the boiler inlet, with the boiler
operating.
Installation pipes MUST be fitted in accordance with BS. 6891.
Pipework from the meter to the boiler MUST be of an adequate
size.
The complete installation MUST be tested for gas soundness and
purged as described in the above code.
FLUE INSTALLATION
Some pluming may occur at the termination so terminal
positions where this could cause a nuisance should be avoided.
The flue must be installed in accordance with the
recommendations of BS. 5440:1.
The following notes are intended for general guidance:-
1. The boiler MUST be installed so that the terminal is exposed
to external air.
2. It is important that the position of the terminal allows the free
passage of air across it at all times.
3. Minimum acceptable spacing from the terminal to
obstructions and ventilation openings are specified in

GENERAL
WATER CIRCULATION SYSTEM
The boiler must NOT be used for direct hot water supply. The boiler
is suitable for connection to pumped open vent central heating
systems, pumped central heating combined with pumped or gravity
indirect domestic hot water supply systems.
The boiler is NOT suitable for gravity heating systems. The hydraulic
resistance of the boilers at maximum output with 11
temperature differentials are shown in the graph below.
The central heating system should be in accordance with
BS. 6798 and, in addition, for smallbore and microbore systems,
BS. 5449:1.
The domestic hot water system, if applicable, should be in
accordance with the relevant recommendations of BS. 5546.
Copper tubing to BS. 2871:1 is recommended for water carrying
pipework.
The hot water storage cylinder MUST be of the indirect type and
should preferably be manufactured of copper.
Single feed, indirect cylinders are not recommended and MUST
NOT be used on sealed systems.
The hot water cylinder and ancillary pipework not forming part of
the useful heating surface should be lagged to prevent heat loss
and any possible freezing - particularly where pipes run through
roof spaces and ventilated underfloor spaces.
IMPORTANT
The boiler must be vented. If venting cannot be done via a flow
connection a separate vent MUST be fitted by the installer.
Draining taps MUST be located in accessible positions, which
permit the draining of the whole system - including the boiler and
hot water storage vessel. They should be at least
size and be in accordance with BS. 2879.
If required, a drain tap (not supplied) may be fitted to an unused
bottom (1" BSP) tapping on the front of the boiler.

THERMOSTATIC RADIATOR VALVES
Caradon Plumbing Limited recommend that heating systems
utilising full thermostatic radiator valve control of temperature in
individual rooms should also be fitted with a room thermostat
controlling the temperature in a space served by radiators not fitted
with such a valve, as stated in BS. 5449.
When thermostatic radiator valves are used, the space heating
temperature control over a living / dining area or hallway having a
heating requirement of at least 10% of the boiler heat output should
be achieved using a room thermostat, whilst other rooms are
individually controlled by thermostatic radiator valves. However, if
the system employs thermostatic radiator valves on all radiators
or two port valves without end switches then a bypass must be
fitted in order to ensure a flow of water should all the valves be in
the closed position.
ELECTRICAL SUPPLY
WARNING. The appliance MUST be efficiently earthed.
Wiring external to the appliance MUST be in accordance with the
current I.E.E. (BS 7671) Wiring Regulations and any local
regulations which apply.
The boiler is supplied for 230 V ~ 50 Hz single phase. The fuse
rating is 3A.
Connection must be made in a way that allows complete isolation
of the electrical supply - such as a double pole switch, having a
1/8") contact separation in both poles, or a plug and socket
3mm (
serving only the boiler and system controls.
The means of isolation must be accessible to the user after
installation.
For bathroom installations the point of connection to the mains
must be situated outside the bathroom.
