Gas Furnace Venting Options

A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace.

Gas furnace venting options. It draws air from within the house for combustion. This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner. These pipes are not only environmentally friendly for residential use but also authorized for use by regulatory bodies and insurance companies. Measure the distance from the furnace vent to the chimney.

Purchase the correct size metal vent pipe from a home improvement store and make sure you get enough elbow joints to give the vent s path the necessary twists and turns. So which type of venting system should your furnace have. When the vent is withdrawing air from the house it expels the gas outside through 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. So no matter where you live or whether your home is small or large goodman probably has a gas furnace to help keep your home warm and comfortable. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof. Gases produced during combustion are very hot and as such easily rise through the flue.

These byproducts in the form of combustion gases must be removed from your home via a venting system. The 90 afue rating on these gas furnaces means that 90 cents of every energy dollar warms your home thus wasting very few energy dollars. Type b vents are a standard design that most modern gas furnaces use. The condensing furnace produces condensed exhaust gases that contain water and carbon dioxide which together form carbonic acid that results in a corrosive condensate.

A conventional furnace vents these combustion gases through a vertical exhaust system that is attached to the furnace. The air is then vented outside through a b vent pipe which is set vertically to expel combustion air through the roof. Features vary by model 90 afue furnaces. That s because the combustion byproducts are in a gaseous form so the gases can float up through the flue pipe and out of your roof.

Natural vent pipes can be installed fairly easily and costs are fairly modest making them a popular choice. In comparing the venting of exhaust gases from a high efficiency furnace boiler or water heater with the venting of exhaust gases from a conventional heating system it will be immediately obvious that the high efficiency equipment exhaust is produced at a low enough temperature that it is vented through comparably small diameter plastic piping rather than a cooled fire protected metal heating vent. Should my furnace flue pipe go through the roof or the side of the house. Therefore only special types of plastic are recommended by furnace manufacturers for venting and condensate drainage in a condensing furnace.

That depends on whether you have a standard efficiency or a high efficiency furnace. Also known as the type b this vent is operating on the natural air convection.
