A system designed to safely exhaust combustion byproducts from a specific type of heating appliance and draw in fresh air for combustion is generally comprised of specialized pipes, connectors, and terminals. For example, the components might include a length of inner and outer pipe, elbows for navigating building structures, a termination cap designed to prevent backdrafts and weather intrusion, and securing bands for leak-proof connections.
Such a system is crucial for maintaining indoor air quality and ensuring the safe operation of the appliance. It eliminates the need for a traditional chimney, offering greater flexibility in appliance placement within a building. This system has become increasingly prevalent due to its energy efficiency, ease of installation, and ability to be installed in homes without pre-existing chimneys.
