Most old gas furnaces use such a mechanism while modern furnaces use the b pipes.
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.
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.

The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber.
This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner.
A conventional furnace vents these combustion gases through a vertical exhaust system that is attached to the furnace.
When the vent is withdrawing air from the house it expels the gas outside through the vent.
Features vary by model 90 afue furnaces.
Also known as the type b this vent is operating on the natural air convection.
The condensing furnace produces condensed exhaust gases that contain water and carbon dioxide which together form carbonic acid that results in a corrosive condensate.
These pipes are not only environmentally friendly for residential use but also authorized for use by regulatory bodies and insurance companies.
It draws air from within the house for combustion.
The furnace uses an exhaust vent motor that pushes the exhaust gas through the vent pipe creating a positive static pressure in the vent.
Gases produced during combustion are very hot and as such easily rise through the flue.
Natural vent pipes can be installed fairly easily and costs are fairly modest making them a popular choice.
These byproducts in the form of combustion gases must be removed from your home via a venting system.
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.
A furnace that uses natural gas to heat your home produces byproducts as part of this process.
Type b vents are a standard design that most modern gas furnaces use.
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.
Should my furnace flue pipe go through the roof or the side of the house.
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.
Measure the distance from the furnace vent to the chimney.
The air is then vented outside through a b vent pipe which is set vertically to expel combustion air through the roof.
So which type of venting system should your furnace have.
