SECTION 1 - GENERAL

1.5 SAFETY

Current Gas Safety (installation and use) regulations or rules 

in force: 

The appliance is suitable only for installation in GB and IE and 

should be installed in accordance with the rules in force.
In GB, the installation must be carried out by a Gas Safe 

Registered Engineer.  It must be carried out in accordance with 

the relevant requirements of the:
•  Gas Safety (Installation and Use) Regulations
•  The appropriate Building Regulations, either The Building 

Regulations, The Building Regulations (Scotland), Building 

Regulations (Northern Ireland)

•  The Water Fittings Regulations or Water byelaws in Scotland
•  The Current I.E.E. Wiring Regulations

Where no specific instructions are given, reference should be 

made to the relevant British Standard Code of Practice.
In IE, the installation must be carried out by a Registered Gas 

Installer (RGII) and installed in accordance with the current edition 

of I.S.813 “Domestic Gas Installations”, the current Building 

Regulations and reference should be made to the current ETCI 

rules for electrical installation.
Detailed recommendations are contained in the following British 

Standard Codes of Practice:

BS. 5440:1

IMPORTANT.

 These appliances are CE certificated for safety 

and performance. It is, therefore, important that no external 

control devices, e.g. flue dampers, economisers etc., are 

directly connected to these appliances unless covered by 

these Installation and Servicing Instructions or as otherwise 

recommended by 

Ideal Boilers

 in writing. If in doubt please 

enquire.
Any direct connection of a control device not approved by 

Ideal 

Boilers

 could invalidate the certification and the normal appliance 

warranty.  It could also infringe the Gas Safety Regulations and 

the above regulations.

1.6  SAFE HANDLING OF SUBSTANCES

No asbestos, mercury or CFCs are included in any part of the 

boiler or its manufacture.

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/7:2006 - 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. 813:2002.
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 

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.

Braces for compartments must be easily removable for service access.
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.
