Installation & Servicing
GENERAL
LOCATION OF BOILER
The boiler must be installed on a flat and vertical wall, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.
The boiler may be fitted on a combustible wall and insulation
between the wall and the boiler is not necessary - unless required
by the local authority.
The boiler must not be fitted outside.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it should be
fitted in accordance with the Institute of Gas Engineering document
IGE/UP/7:1998.
Bathrooms
This range of appliances is rated
IP 1XB.
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. For Ireland reference should be
made to the current ETCI rules for electrical installations and
I.S.813:2002.
If the appliance is to be installed in a room containing a bath or
shower then, providing waterjets are not going to be used for
cleaning purposes (such as communal baths/showers), the
appliance can be installed in Zone 3, as detailed in BS.7671.
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 MUST be designed
and constructed specially for this purpose.
An existing cupboard or compartment may be used, provided it
is modified for the purpose.
In both cases details of essential features of cupboards/
compartment design, including airing cupboard installation, are
to conform to the following :
z
BS. 6798.
z
The position selected for installation MUST allow adequate
space for servicing in front of the boiler and for air circulation
around the boiler. Refer to 'Air Supply'.
z
For the minimum clearances required for safety and
subsequent service refer to the wall mounting diagram,
Frame 2. In addition, sufficient space may be required to allow
lifting access to the wall mounting plate.
GAS SUPPLY
A local propane supplier should be consulted, at the installation
planning stage, in order to establish the availability of an adequate
supply of gas.
Installation pipes, cylinders and pressure regulators MUST be
fitted in accordance with BS. 5482.1. In IE refer to I.S. 813:2002.
Pipework from the supply to the boiler MUST be of an adequate
size.
Bulk tank installations must comply with the Home Office code of
practice for the storage of liquefied petroleum gas at fixed
installations.
The complete installation MUST be tested for gas soundness and
purged as described in the above code.
FLUE INSTALLATION
Pluming may occur at the terminal so terminal positions which
would cause a nuisance should be avoided.
The flue must be installed in accordance with the
recommendations of BS. 5440-1:2000. In IE refer to I.S. 813:2002.
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 Table 3.
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.
Terminals guards are available from boiler suppliers - ask for
TFC Flue Guard, Model No. K6-round, plastic coated. In case of
difficulty seek advice from:
Grasslin (UK) Ltd., Tower House, Vale Rise, Tonbridge,
Kent TN9 1TB.
Tel: +44 (0) 1732 359 888. Fax: +44 (0) 1732 354 445
www.tfc-group.co.uk
Ensure that the guard is fitted centrally.
5.
The flue assembly shall be so placed or shielded as to prevent
ignition or damage to any part of any building.
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.5440-1:2000. In IE refer to I.S. 813:2002.
IMPORTANT
. It is absolutely ESSENTIAL to ensure, in practice, that
products of combustion discharging from the terminal cannot re-
enter the building or any other adjacent building through ventilators,
windows, doors, other sources of natural air infiltration, or forced
ventilation/air conditioning.
If this should occur, the appliance MUST be turned OFF, labelled
'unsafe' and corrective action taken.
