BOILER INSTALLATION

1.1 INTROdUCTION.

The Alpha InTec 50CS is a floor standing, high efficiency, condensing, room-sealed combination boiler. The burner is lit electronically and the heat

output is controlled by a modulating fan and gas valve.

This is a combination boiler (for domestic use only) providing both central heating and domestic hot water at mains pressure.

The boiler is supplied with a pump, pressure relief valve, expansion vessel and pressure gauge fully assembled and tested. It is designed for use with a

fully pumped, sealed and pressurised central heating system.

The boiler must be installed indoors in a frost free environment.

IMPORTANT

This boiler meets the requirements for Building Regulations for unvented hot water storage systems and the Local Authority must be notified of the

intention to install. Therefore the installation must be carried out by a person competent to install unvented hot water systems.

It is the law that all gas appliances are installed by a competent person, i.e. Gas Safe registered personnel, in accordance with the following

recommendations:-

Current Gas Safety (Installation and Use) Regulations

All current Building Regulations issued by the Department of the Environment, i.e. Approved Document L1.

Building Standards (Scotland) (Consolidation) Regulations issued by the Scottish Development Department

UK Water Regulations/Byelaws (Scotland)

Health & Safety Document No. 635 (The Electricity At Work Regulations 1989)

The installation should also be in accordance with the following British Standard Codes of Practice:-

BS 5440:1

Flues

BS 5546:

Installation of hot water supplies for domestic purposes

BS 6700:

Design, installation, testing and maintenance of services supplying water

BS 6798:

Installation of gas fired hot water boilers

BS 6891:

Gas installation

BS 7593:

Code of Practice for treatment of water in heating systems

BS 7671:

Requirements for electrical installations, IEE Wiring Regulations

BS EN 12828

Heating systems in Buildings. Design for water based heating systems

BS EN 12831

BS EN 14336

Heating systems in Buildings. Installation and commissioning of water based heating systems

Reference should be made to DEFRA document 'Guide to condensing boiler installation assessment procedures for dwellings'.

If installation is in a timber framed building, refer to the Institute of Gas Engineers document IGE/UP/7.

This appliance meets the requirements of IPX4D, i.e. degree of protection against moisture.

This appliance contains no asbestos and no substances have been used in the construction process that contravene the COSHH Regulations (Control

of Substances Hazardous to Health).

Failure to install this appliance correctly could lead to prosecution. It is in your own interest and that of safety to ensure that the law is complied with.

Manufacturer's instructions must NOT be taken in anyway as over-riding statutory obligations.

Notes:

1. Ensure that the Benchmark Checklist has been completed after the boiler has been installed and commissioned.

2. It is the law that all boiler installations are registered by the installer through the Gas Safe Gas Work Notification Scheme.

3. The boiler must only be used with Alpha CD condensing flue components.

NOTE: The boiler can be supplied ready for use with Propane (LPG).

The LPG boiler is also designed for use with a fully pumped, sealed and pressurised heating system.

In addition to the regulations and requirements stated in these installation and servicing instructions, LPG boilers must be installed in accordance

with BS 5482:1 - The Installation of Propane Burning Appliances in Permanent Dwellings.

Installation pipes, cylinders and pressure regulators for LPG boilers should be fitted in accordance with BS5482:1. Bulk tank installations must comply

with the requirements of the Home Office code of practice for the storage of liquefied petroleum gas at fixed installations.

LPG boilers must not be installed in a room or internal space below ground level, e.g. in a basement or cellar, except where at least one side is open to

ground level.

LPG supply pipes must be capable of delivering the required quantity of gas in addition to the demand from any other appliances in the house. The

complete installation must be tested for gas soundness against leaks.

LPG boilers have been tested and factory set for use with Propane (LPG), it should only be necessary to ensure the correct gas supply pressure of 37 mbar is

available.
