Can You Vent A Gas Furnace Through A Wall

I think don t it is possible to vent a 95 efficiency furnace up through an existing chimney.

Can you vent a gas furnace through a wall.

You can go through the wall then run a vent pipe straight up above the roofline. Only units designed for it can have a vent go thru the wall and end there without a vertical stack. Adhere to them even if you are building the vent on your own. Proper sidewall venting requires installing separate vent pipes horizontally so that they vent to the outdoors through a wall of your home.

I have not heard of high efficieny only lasting 10 13 years. The answer is yes and no. The exhaust gas is too cool for it to rise. I would be very leary of a hvac contractor would not do this.

Distances pertaining to the furnace combustion air intake and exhaust vent distances from the indoor furnace cabinet itself and nearby surfaces materials or combustibles. These ventilation pipes should be isolated from the furnace combustion chamber and made airtight to eliminate the possibility of combustion gas leakage. The vent pipe must overlap at each joint to prevent gas from leaking. You cannot just take the vent off an 80 efficient furnace and run it out a side wall.

Gas furnaces usually come with their own specifications. So what does this mean. When installing a direct vent wall furnace there will be two sets of clearance distances that must be respected.
