Propane Installation & Servicing

GENERAL

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 should 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 :

BS. 6798.

The position selected for installation MUST allow adequate
space for servicing in front of the boiler and for air circulation
around the boiler, see section on 'Air Supply'.

For the minimum clearances required for safety and
subsequent service, see 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. 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.

7. Where it is essential that the terminal wall plate is fitted, i.e.

wall thicknesses over 600mm (23

1/2

") or with an inaccurately

cut hole, the minimum spacing in Table 3 Nos. 2,3, 4, 5 and 6
would be 60mm (2

1/2

") in order to allow the terminal wall

plate to be fitted.

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 Frame 10.

Terminals guards are available from boiler suppliers. Ask for
TFC Flue Guard, Model K1. 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.
