Location Of Boiler; Flue Installation; Gas Supply - IDEAL HE15 Installation And Servicing

LOCATION OF BOILER

The boiler must be installed on a flat and level floor, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.
The boiler may be fitted on a combustible floor. Insulation is
not necessary, unless required by the local authority.
For electrical safety reasons there must be no access 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/7:1998.
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, 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 water jets are not going to be used for
cleaning purposes (as in communal baths/showers), the
appliance can be installed in Zone 3, 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 Frame 2.
! This position MUST also permit the provision of a
satisfactory flue termination.
! Boiler may be fitted under a worktop/surface. Boiler can be
fitted behind a kitchen cupboard door without need for
ventilation.

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 CORGI registered engineer. In IE by a Competent Person.
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.
N.B. The principle of the 1:1 gas valve ensures that the
mexico HE range is able to deliver their full output at inlet
pressures down to 14mb. However if dynamic pressures
below 20mb are experienced ensure this is adequate for ALL
other gas appliances in the property.

GENERAL
IMPORTANT.
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, i.e. no longer than 20m and not
less than 15mm O.D.
The complete installation MUST be tested for gas soundness
and purged as described in the above code.

FLUE INSTALLATION

Pluming will 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.
Table 3 - Balanced flue terminal position
Terminal Position
1. Directly below or alongside an
opening window, air brick or other
ventilation opening
2. Below guttering, drain pipes or soil
pipes
3. Below eaves
4. Below balconies or a car port roof
5. From vertical drain pipes or soil pipes
6. From an internal or external corner or
to a boundary along side the terminal.
7. Above adjacent ground, roof or
balcony level
8. From a surface or boundary facing
the terminal
9. From a terminal facing a terminal
10. From an opening in a car port
(e.g. door or window) into dwelling
11. Vertically from a terminal on the
same wall
12. Horizontally from a terminal on the wall
* Only 1 reduction down to 25mm is allowable per installation.
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.
Ensure that the guard is fitted centrally.
Terminal guards are available from boiler suppliers. Ask for
TFC Flue Guard Model No. K6 (round plastic-coated). In
