This is a retro-fitted combustion air vent for low kilowatt stoves and fires. The mini draught reducing internal panel easily disperses air in an even manner in to the room, allowing for improved comfort. You can simply wallpaper or paint the panel to match your room, thus allowing it to blend in to the surroundings.
The transfer of water across the cavity is prevented by the external water baffle. You'll find this component very easy to position and align thanks to the interlocking components, and as a reminder, the grille is embossed with the words 'DO NOT BLOCK'.
The component is HETAS approved of course, allowing it to be used safely with solid fuel appliances. Packaged with screws to allow the securing of the panel and the external grille is UV stabilised, thus slowing down any sunlight effects.
