Fresh Air Ducting

It is an open duct that goes from an outside vent that serves as a path for clean fresh air into the home. It often goes to the room where the furnace is or the basement.These fresh air vents are commonly installed for fireplaces, gas dryers, or even gas heaters. They work by allowing a passageway for air from the inside air to the exterior air through a vent and flue. If you did not have fresh air intake vents, your gas appliances might solely use your oxygen in your home as fuel.
