IMPORTANT NOTICE
4.4.1
If the combination boiler is to be fitted in a
timber framed building it should be fitted in
accordance with the British Gas Publication
Guide for Gas Installations in Timber Frame
Housing Reference DM2. If in doubt advice
must be sought from the local gas supplier.
The combination boiler may be installed in
any room or internal space, although partic-
ular attention is drawn to the requirements
of the current I.E.E. Wiring Regulations, and
in Scotland the electrical provisions of the
Building Regulations applicable in Scot-
land, with respect to the installation of the
combination boiler in a room or internal
space containing a bath or shower.
Where a room sealed appliance is installed
in a room containing a bath or shower, any
electrical switch or appliance control, utilis-
ing mains electricity should be so situated
that it cannot be touched by a person using
a bath or shower.
A compartment used to enclose the combi-
nation boiler MUST be designed and con-
structed specifically for this purpose. An
existing cupboard, or compartment, may be
used provided it is modified accordingly.
Samples of the CSI combination boiler have
been examined by B.G. Technology Notified
Body, and is certified to comply with the
essential requirements of the Gas Appli-
ance Directive 90/396/EEC, the Low Voltage
Directive 72/23/EEC and shows compliance
with the Electro Magnetic Compatibility
Directive 89/336/EEC and are therefore per-
mitted to carry the CE Mark.

4.5 GAS SUPPLY
4.5.1
A gas meter is connected to the service
pipe by the Local Gas Region or the Local
Gas Region contractor. An existing meter
should be checked preferably by the Gas
Region to ensure that the meter is ade-
quate to deal with the rate of gas supply
required for all appliances it serves. Instal-
lation pipes should be fitted in accordance
with BS 6891. Pipework from the meter to
the boiler must be of adequate size (22 mm)
min. To within at least 3 metre of the boiler
(15 mm) min. can then be used for remain-
ing pipe work to the appliance. A smaller
size than the boiler inlet gas connection
should not be used. The complete installa-
tion must be tested for soundness as
described in the above Code.
N.B. if the gas supply for the boiler serves
other appliances ensure an adequate sup-
ply is available both to the boiler and the
other appliances when they are in use at
the same time.
4.6 FLUE SYSTEM
4.6.1
The terminal should be located where dis-
persal of combustion products is not imped-
ed and with due regard for the damage or
discolouration that might occur to building
products in the vicinity (see fig. 6).
The terminal must not be located in a place
where it is likely to cause a nuisance.
In cold and/or humid weather water vapour
may condense on leaving the flue terminal.
The effect of such steaming must be con-
sidered.
The terminal must not be closer than 25
mm. (1 in) to any combustible material. For
protection of combustibles, refer to BS
5440.1.
Where a flue terminal is installed less than
1000 mm. from a plastic, or painted gutter;
or 500 mm from painted eaves, an alumini-
um shield 1000 mm. long, should be fitted
to the underside of the gutter or painted
surface.
Pluming will occur at the terminal so, where
possible, terminal positions which could
cause a nuisance should be avoided.
The flue must be installed in accordance with
the recommendations of BS 5440: Part 1.
IMPORTANT NOTES
For greater flue lengths see twin flue
instructions.
Flue must be positioned in a place not likely
to cause a nuisance.
IMPORTANT: The following notes are
intended for general guidance.
The boiler MUST be installed so that the
terminal is exposed to external air.
It is important that the position of the termi-
nal allows the free passage of air across it
at all times.
Minimum acceptable spacing from the ter-
minal to obstructions and ventilation open-
ing are specified in Fig. 6.
Note positions: Due
to the
terminal
design,
installation is possible with clearances less
than those specified in BS 5440, Part 1.
