Venting gas furnace through wall.

The space saving direct vent furnace design mounts to an exterior wall and the adjustable vent assembly adjusts to fit walls from 4 1 2 in. Gas or oil fired side wall power vents are provided by several manufacturers listed at the end of this article. These ventilation pipes should be isolated from the furnace combustion chamber and made airtight to eliminate the possibility of combustion gas leakage. Adhere to them even if you are building the vent on your own.

Not familiar with your specific furnace but there were literally thousands of 80 furnaces horizontally vented through sidewalls in the late 80s and 90s. The basement ceiling is about 6 1 2 or 7 feet high. If your furnace has an afue rating below 90 percent it will most likely have a flue pipe that goes up through your roof. Gas furnaces usually come with their own specifications.

The diameter of the vent pipe should always be larger than that of the gas furnace flue ensuring that no gas escapes from the pipe. For clean comfortable heat when and where you want it the gas flame is completely sealed inside away from all contact with room air. That depends on whether you have a standard efficiency or a high efficiency furnace. Should my furnace flue pipe go through the roof or the side of the house.

Direct venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort. The vent pipe must overlap at each joint to prevent gas from leaking. Proper sidewall venting requires installing separate vent pipes horizontally so that they vent to the outdoors through a wall of your home. It also increases living space by cutting out interior chases.

The fix was to use double wall b vent with an external power venter. 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. If it went out the chimney it would leave more headroom.
