1.7 LOCATION OF BOILER

The boiler must be installed on a flat and vertical internal 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.
For electrical safety reasons there must be no access available
from the back of the boiler.
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 - Edition 2.
Bathroom Installations
This appliance is rated IP20.
The boiler may be installed in any room or internal space,
although particular attention is drawn to the requirements of
the current IEE (BS 7671) Wiring Regulations and 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 IE reference should be made to
the current ETCI rules for electrical installations and I.S. 813.
If the appliance is to be installed in a room containing a bath
or shower then, providing water jets are not going to be used
for cleaning purposes (as in communal baths/showers), the
appliance must be installed beyond Zone 2, as detailed in BS
7671.

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 (No cupboard ventilation is required - see 'Air Supply'
for details).
• The position selected for installation MUST allow adequate
space for servicing in front of the boiler.
• For the minimum clearances required for safety and
subsequent service, see the wall mounting template and
Section 1.16. In addition, sufficient space may be required to
allow lifting access to the wall mounting plate.

1.8 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 MUST be installed on a gas supply with a governed
meter only.
A gas meter can only be connected by the local gas supplier or
by a Gas Safe Registered Engineer. In IE by a Registered Gas
Installer (RGII).
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.
It is the responsibility of the Gas Installer to size the gas
installation pipework in accordance with BS 6891. Whilst the
principle of the 1:1 gas valve ensures the Vogue range is able
to deliver it is full output at inlet pressures as low as 14mb,
other gas appliances in the property may not be as tolerant.
When operating pressures are found to be below the minimum
meter outlet of 19mb these should be checked to ensure this is
adequate for correct and safe operation.
Allowing for the acceptable pressure loss of 1mb across the
installation pipework, it can be assumed that a minimum permitted
operating pressure of 18mb will be delivered to the inlet of
the appliance. (Reference BS 6400-1 Clause 6.2 Pressure
Absorption).
The external gas cock could further reduce the operating pressure
when measured at its test point. The pressure drop is relative to
the heat input to the boiler (kW), refer to graph below.

IMPORTANT.
Installation pipes must be fitted in accordance with BS 6891. In IE
3G8913a
refer to IS.813.
The complete installation MUST be tested for gas tightness and
purged as described in the above code.

1.9 FLUE INSTALLATION

Pluming will occur at the terminal 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.
In IE refer to I.S. 813.
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 4.
