How do venting systems need to be installed for furnace units?
Proper sidewall venting requires installing separate vent pipes horizontally so that they vent to the outdoors through a wall of your home. These ventilation pipes should be isolated from the furnace combustion chamber and made airtight to eliminate the possibility of combustion gas leakage.
Does gas furnace need exhaust?
Furnace Venting Systems Vent systems are an important component of the combustion process of a gas furnace. A venting system ensures that the hazardous gasses are removed from the heat exchangers and burners at the end of a heating cycle.
Does a furnace exhaust have to be straight?
The vent connector should exit the furnace straight for at least 18 in. before any turns are made. This allows the flue gases to gain some velocity before meeting any resistance to flow.
What is the code for venting a gas furnace?
503.6. A gas vent shall terminate in accordance with one of the following: 1. Gas vents that are 12 inches (305 mm) or less in size and located not less than 8 feet (2438 mm) from a vertical wall or similar obstruction shall terminate above the roof in accordance with Figure 503.6. 5.
Where is furnace exhaust pipe?
They should be near where your furnace is on the inside. Normally, they are a set of curved pipes (PVC, CPVC, or ABS) near the foundation, although sometimes they are on or near the roof.
What type of pipe is used for furnace exhaust?
Traditional gas-fired, forced-air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes, or chimneys. In contrast, modern high-efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials—such as SS, PVC, CPVC, or ABS—for their exhaust vents.
How far can you run a furnace exhaust?
The maximum vertical distance you can run a furnace exhaust vent is about 15 feet. If there is a forced air inlet within 10 feet of the exhaust vent, the exhaust gas ventilation terminal should be positioned at least 3 feet above it.
What exhaust comes out of a gas furnace?
The exhaust is mainly water vapor and carbon dioxide, but the absolute majority of furnaces also form a wide range of byproducts (particulate matter, nitrogen dioxide, sulfur dioxide, hydrocarbons, carbon monoxide, etc.); carbon monoxide is especially dangerous as this invisible, odorless gas can lead to poisoning.
Where does a gas furnace vent?
In a standard-efficiency furnace, a flue pipe is attached to the heat exchanger and combustion gases exit the heat exchanger through that pipe. The flue pipe typically extends upwards and out of the home's roof, where the gases are expelled outside.
What is the minimum size flue pipe that should be attached to a gas furnace?
What is the minimum size flue pipe that should be attached to a gas furnace? The inside diameter of the hole should match the inside diameter of the pipe you buy. It must never be smaller or it will leak. The average stove and furnace requires a 3 inch diameter pipe, but can be as large as 8 inches.
