Installation

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.
The boiler is to be installed only on a gas supply with a
governed meter.
A gas meter can only be connected by the local gas supplier or
by a local regional contractor.
Check that the appliance is suitable for the proposed gas
supply. 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 gas pressure of
20 mbar MUST be available at the boiler inlet, with the boiler
operating.
Installation pipes MUST be fitted in accordance with BS. 6891.
In IE refer to I.S. 813:2002. Pipework from the meter to the
boiler MUST be of an adequate size. Both 100 FF and 125 FF
models should be piped in 22mm minimum. The final metre
may be run in 15mm if it is visible.
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.5440-1:2000. 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.

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 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.

6. 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 & 6 - would be 60mm (2

1/2

") in order to allow

the terminal wall plate to be fitted.

7. The flue assembly shall be so placed or shielded as to

prevent ignition or damage to any part of any building.

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

WARNING

For top outlet installation (100 FF only) the flue terminal MUST
always be in the horizontal position.

The terminal assembly can be adapted to accommodate various
wall thicknesses. Refer to Frames 7 & 36.

AIR SUPPLY

Detailed recommendations for air supply are given in
BS.5440:2. In IE refer to I.S. 813:2002.

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.
