Also known as a Fresh Air Intake device, our Outside Air Kits are available with 3″ or 4″ diameters. These kits help prevent backdraft smoking caused by negative pressure in the home while drawing fresh air from the outside to fuel your wood-burning fireplace. Outside Air Kits assist your fireplace in burning more evenly. Meeting most building code requirements, they also dramatically reduce pollution and smoke byproducts from your fire.
