The vent cap installs on the outside wall of the home.Click to see full answer. Keeping this in view, what does direct vent furnace mean?”Direct vent” refers to a sealed-combustion system in which air for combustion is drawn from the outdoors, and waste combustion gasses are exhausted to the outdoors. “Direct vent” does not simply mean that all gasses from combustion are vented to the exterior of the structure in which it is installed.Beside above, how is a gas furnace vented? Natural Vent Gases produced during combustion are very hot and as such, easily rise through the flue. The air is then vented outside through a B-vent pipe which is set vertically to expel combustion air through the roof. The tendency to back-draft also raises questions over furnace safety where such pipes are used. Correspondingly, how does direct vent furnace work? A direct vent heater pulls its air from the outside and then vents it back outside again, directly through the wall behind the heater—no need for a complex system of exhaust ducts or a chimney to carry the fumes to the roof.Where are furnace vents located?Combustion vents must be located at least 3 feet above any building opening within 10 feet. Non-combustion appliance vents should be located 3 feet from any building opening.
