Bathroom Installations
The boiler may be installed in any room or internal space, although
particular attention is drawn to the requirements of the current I.E.E.
(BS.7671) Wiring Regulations and, in Scotland, the electrical
provisions of the building regulations applicable in Scotland with
respect to the installation of the 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 then the appliance and any electrical switch or
appliance control utilising mains electricity should be so situated
that it cannot be touched by a person using the bath or shower.
Where installation will be in an unusual location, special procedures
may be necessary and BS 6798 gives detailed guidance on this
aspect.
Compartment Installations
A compartment used to enclose the boiler should be designed
and constructed specially for this purpose.
An existing cupboard or compartment may be used, provided
that it is modified for the purpose.
In both cases details of essential features of cupboard /
compartment design, including airing cupboard installation, are to
conform to the following:
!
BS. 6798.
!
The position selected for installation MUST allow adequate
space for servicing in front of the boiler. Ventilation of the
compartment is not necessary.
!
For the minimum clearances required for safety and subsequent
service, see the wall mounting template and Frame 2. In
addition, sufficient space may be required to allow lifting access
to the wall mounting plate.
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.
A gas meter can only be connected by the local gas supplier or by
a registered CORGI engineer.
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 working gas pressure of
20 mbar MUST be available at the boiler inlet.
Installation pipes MUST be fitted in accordance with BS. 6891.
Pipework from the meter to the boiler MUST be of an adequate
size, i.e. not less than 15mm O.D. Note.
For pipe runs greater
than 3m (10'), 22mm O.D. pipe must be used.
Do not use pipes of smaller size than the boiler inlet gas connection.
The complete installation MUST be tested for gas soundness and
purged as described in the above code.
FLUE INSTALLATION
Pluming will occur at the termination 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.
The following notes are intended for general guidance.
GENERAL
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
Table 3.
Note positions 2-6
: Due to the terminal design, installation is
possible with clearances less than those specified in BS 5440,
Part 1.
Table 3 - Balanced flue terminal position
4. Where the lowest part of the terminal is fitted less than 2m
(6'6") above a balcony, above ground or above a flat roof to
which people have access, then the terminal MUST be
protected by a purpose designed guard. The minimum spacing
in Table 3, Nos. 2, 3, 4, 5 and 6 would be 75mm, in order to
allow a terminal guard to be fitted.
Terminals guards are available from boiler suppliers - ask for
Tower Flue Guard, Model K1. In case of difficulty seek advice
from:
Tower Flue Components Ltd.,
Vale Rise, Tonbridge, Kent TN9 1TB
Telephone No. 01732 351 555.
Ensure that the guard is fitted centrally.
5. Where the terminal is fitted within 850mm (34") of a plastic or
painted gutter or 450mm (18") of painted eaves then an
aluminium shield at least 750mm (30") long should be fitted to
the underside of the gutter or painted surface.
6. The air inlet/products outlet duct and the terminal of the boiler
MUST NOT be closer than 25mm (1") to combustible material.
Detailed recommendations on the protection of combustible
material are given in BS. 5440: 1990.
7. Where it is essential that the terminal wall plate
is fitted, i.e.
wall thicknesses over 610mm (24") or with an inaccurately cut
hole, the minimum spacing in Table 3, Nos. 2, 3, 4, 5 and 6
would be 60mm (2.4") in order to allow the terminal wall plate
to be fitted.
Terminal Position
Minimum Spacing
1. Directly below or alongside an
opening window, air vent or other
300 mm (12")
ventilation opening
2. Below guttering, drain pipes or soil
pipes
25 mm
( 1")
3. Below eaves
25 mm
( 1")
4. Below balconies or a car port roof
25 mm
( 1")
5. From vertical drain pipes or soil pipes
25 mm
( 1")
6. From internal or external corners
25 mm
( 1")
7. Above adjacent ground, roof or
balcony level
300 mm (12")
8. From a surface facing the terminal
600 mm (24")
9. From a terminal facing a terminal
1200 mm (48")
10. From an opening in a car port
(e.g. door or window) into dwelling
1200 mm (48")
11. Vertically from a terminal on the
same wall
1500 mm (60")
12. Horizontally from a terminal on the wall
300 mm (12")
