Furnace vent pipe through wall. What to know before you install b vent furnace pipe. The outer pipe draws air for combustion from outside and the smaller pipe occupies the inner position and is used to vent the exhaust fumes. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof. When the vent is withdrawing air from the house it expels the gas outside through the vent.
Each of these ameri vent gas pipes features rugged double wall construction with aluminum alloy 1100 3003 or 3105 inner pipe and corrosion resistant galvanized steel outer pipe. That depends on whether you have a standard efficiency or a high efficiency furnace. The furnace uses an exhaust vent motor that pushes the exhaust gas through the vent pipe creating a positive static pressure in the vent. The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber.
Also known as the type b this vent is operating on the natural air convection. Gas appliance direct vent clearances distances from direct gas vent to building features sidewall vent direct vent direct exhaust systems for gas fired heaters water heaters other appliances. Table illustrations of the required space between a direct or side wall vent for a gas fired heating appliance and building windows doors corners gas meter air intakes sidewalks balconies. Piping can be set horizontally to allow venting through a sidewall or vertical installation can also be undertaken to allow venting through the roof.
Should my furnace flue pipe go through the roof or the side of the house. So which type of venting system should your furnace have. Direct venting uses a power ventilating blower or fan and in some models a heat exchanger plenum to cool outgoing gases passing through the building wall sidewall direct exhaust or roof or through an existing unused chimney through which a vent pipe is passed vertical direct exhaust. A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace.
