Venting High Efficiency Furnace Through Wall

You need to make sure your furnace is venting properly.

Venting high efficiency furnace through wall.

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 this happens the exhaust gases cool and condense creating a slightly acidic by product. The potential danger from the exhaust of a condensing furnace is two fold. So which type of venting system should your furnace have.

Both types of heating systems can vent horizontally through a building wall but the exhaust products of high efficiency or condensing boilers and furnaces are generally cool and have different venting and combustible clearance specifications. The basement ceiling is about 6 1 2 or 7 feet high. These pvc pipes are connected to the furnace and expelled outside. They include a second heat exchanger that reclaims additional heat from the system s exhaust gases before they are vented away.

This high efficiency venting system must be installed when you install the new furnace. If you are venting a high efficient furnace with the pvc piping you can go through a roof or wall. It could either go out the unused walled in chimney that the oil furnace was vented through or they could cut a hole in the concrete block wall and vent it out the side of the house. Don t confuse direct vent heating equipment with the through wall venting and air intake of high efficiency boilers and furnaces.

That depends on whether you have a standard efficiency or a high efficiency furnace. If it went out the chimney it would leave more headroom. Should my furnace flue pipe go through the roof or the side of the house. These are connected to the furnace and routed out to the side of your home.

It is easier to go through the wall next to the furnace and makes it a lot easier to deal with. Condensing gas furnaces achieve their high levels of efficiency by adding another step to the fuel burning and venting process.
