Sometimes the reason a chimney is not able to function properly is not because there are issues with the hearth. Possibly, it is because you need to have better accessory equipment. With the OAC4 Outside Combustion Air Kit, you have a tool that is intended to elevate the efficiency of your fireplace by allowing it to draw in air from the outside so that it can burn effectively, keeping both you and your loved ones warm.
