The LX 24 Fi is a convectional boiler designed to provide both central heating and domestic hot water (DHW). It is particularly well-suited for standard 3–4 bedroom family homes or apartments with up to 15 radiators.

The Lx 24 Fi model is a "room sealed" (Fi) fan-assisted boiler, meaning it draws combustion air from outside and exhausts gases through a coaxial chimney system, making it safe for modern indoor installation. Key Technical Specifications

Before performing any task described in this guide, ensure the boiler is isolated from the electrical and gas supplies unless otherwise stated.
