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 240/280 range of boilers are wall mounted, fan assisted room-sealed combination boilers. 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.
