In the past, fireplaces were often installed without side vents, relying on indoor air to fuel the fire. However, this approach had several drawbacks, including reduced combustion efficiency, increased particulate matter, and a higher risk of carbon monoxide poisoning. Side vents were introduced to address these issues by providing a direct supply of outside air to the fireplace. This outside air is cleaner and contains more oxygen than indoor air, resulting in better combustion, reduced emissions, and a safer burning experience.
How Side Vents Work
Side vents work by drawing in outside air through a duct or pipe that connects to the exterior of the home. This outside air is then directed into the fireplace, where it mixes with the fuel (wood, gas, or other combustible materials) and ignites. The resulting combustion process produces heat, light, and a small amount of exhaust gases, which are vented out of the home through the chimney. The side vents play a crucial role in this process, as they provide the necessary oxygen for complete combustion, reducing the risk of unburned particles, carbon monoxide, and other pollutants.
