1 INTRODUCTION

This supplement is for the LPG model of the boiler; it must be read in conjunction with the 'Installation and Servicing

Instructions' supplied with the boiler and provides the extra information which is particular to LPG.

The Alpha 500E boiler is a wall mounted, fan assisted room-sealed combination boiler with unvented hot water storage. Heat

output is controlled by a modulating gas valve.

The boiler, providing both central heating and domestic hot water at mains pressure, is designed for use with a fully pumped,

sealed and pressurised heating system using only PROPANE gas.

2.2 GAS SUPPLY

The boiler requires a gas rate of 2.4 kg/h (5.3 lb/h) or 4.7 litres/h of liquid gas.

The supply pipes must be capable of delivering this quantity of gas in addition to the demand from any other appliances in the

house. The boiler requires at least a 22 mm gas supply pipe.

The complete installation must be tested for gas soundness against leakage.

The local Propane gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an

adequate supply of gas.

Installation pipes, cylinders and pressure regulators should be fitted in accordance with BS 5482:1. Bulk tank installation must

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

installations.

3 BOILER LOCATION

The boiler 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.

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

5 COMMISSIONING

The boiler has been tested and factory set for use with Propane gas and it should only be necessary to ensure the correct gas

supply pressure of 37 mbar is available.
