Venting High Efficiency Furnace Through Wall

When this happens the exhaust gases cool and condense creating a slightly acidic by product.

These are connected to the furnace and routed out to the side of your home. To combat this issue a high efficiency condensing furnace uses pvc pipes to extract the acidic water from your home. The basement ceiling is about 6 1 2 or 7 feet high. The venting system is installed at the same time as your high efficiency furnace.

Don t confuse direct vent heating equipment with the through wall venting and air intake of high efficiency boilers and furnaces. 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 potential danger from the exhaust of a condensing furnace is two fold. To avoid this problem high efficiency furnace venting requires the use of pvc pipes instead of metal pipes to remove the acidic condensate from your home.

This high efficiency venting system must be installed when you install the new furnace. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof. Should my furnace flue pipe go through the roof or the side of the house. 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.

You need to make sure your furnace is venting properly. That depends on whether you have a standard efficiency or a high efficiency furnace. They include a second heat exchanger that reclaims additional heat from the system s exhaust gases before they are vented away. Condensing gas furnaces achieve their high levels of efficiency by adding another step to the fuel burning and venting process.

It is easier to go through the wall next to the furnace and makes it a lot easier to deal with. If it went out the chimney it would leave more headroom.
