4.6 FLUE SYSTEM
4.6.1
The terminal should be located where
dispersal of combustion products is not
impeded 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
considered
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 aluminium
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 fl ue lengths see alternative fl ue
instructions. Flue must be positioned in a
place not likely to cause a nuisance from
pluming.
IMPORTANT NOTICE:
If the fl ue terminates
less a balcony, above the ground, or above
a fl at roof to which people have access,
then a suitable
terminal guard
must be
fi tted.

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 terminal
allows the free passage of air across it at all
tirnes.
Minimum acceptable spacing from the terminal to
obstructions and ventnation opening are specifi ed
in Fig. 6.
Note positions:
Due to the terminal design,
installation is possible with clearances less than
those specifi ed in BS 5440, Part 1
4.4 IMPORTANT
NOTICE
4.4.1
For installation into timber framed buildings,
please refer to the Institute of Gas Engineers
Document IGE UP/7 instead of 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
particular 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 Scotland, 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,
utilising 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 combination
boiler MUST be designed and constructed
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 Appliance
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
permitted to carry the CE Mark.
The appliance has been tested and approved
by the WRc as meeting the requirements of
G3 and L of the Building regulations and water
Bylaws Scheme - Approved Products.
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 adequate to deal with
the rate of gas supply required for all appliances
it serves. Installation 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
remaining pipe work to the appliance. A smaller
size than the boiler inlet gas connection should
not be used The complete installation 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
supply is available both to the boiler and the
other appliances when they are in use at the
same time.
