GENERAL
GAS SUPPLY
The local Propane supplier should be consulted at the
installation planning stage, in order to establish the availability of
an adequate supply of gas.
Check that the appliance is suitable for the proposed gas supply.
Installation pipes, cylinders and pressure regulators should be
fitted in accordance with BS.5482.1.
Bulk tank installations must comply with the Home Office code
of practice for the storage of liquified petroleum gas at fixed
installations.
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
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. 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 1000mm (39
1/2
") of a
plastic or painted gutter or 500mm (19
1/2
") of painted eaves
then an aluminium shield at least 1000mm (39
1/2
") 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.
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.
TERMINAL
The terminal assembly can be adapted to accommodate various
wall thicknesses. Refer to Frames 9 and 10.
AIR SUPPLY
Detailed recommendations for air supply are given in BS.5440:2.
The following notes are for general guidance:
1.
It is NOT necessary to have a purpose provided air vent in
the room or internal space in which the boiler is installed.
2.
If the boiler is to be installed in a cupboard or compartment,
permanent air vents are required (for cooling purposes) in
the cupboard/compartment, at both high and low levels. The
air vents must either communicate with room/internal space,
or be direct to outside air. The minimum effective areas of the
permanent air vents, required in the cupboard/compartment,
are specified as follows and are related to maximum rated
heat input.
3.
Both air vents MUST communicate with the same room or
internal space or MUST be on the same wall to outside air.
4.
In siting the air vents care must be taken to avoid the
freezing of pipework.
