My house was built in '72. I bought it in 97. I believe the furnace is the same as was installed at the time of construction. I assume it is a very low efficiency unit.
Here is my situation. My roof needs to be replaced. I've discovered that my chimney is no longer sound. There is a very large gap(at least 1" iirc) separating the top half of the chimney, and the lower. There is a SS liner that I installed last year so at least I don't have to worry about CO, or other gases, entering the living space. The gap has come from the ground settling. The lower half sank with the concrete, and the upper half is basically being held up by the rafters.
My furnace is in my utility room which is simply a bricked enclosure. It is only a few feet from the outside wall. I was hoping that I could tear down the chimney and run the flue out of the brick. I see that on high efficiency units, you have to have a fan that pulls the exhaust out of a direct vent configuration. Does that mean that I don't have to have a fan? If I could simply vent it out the brick, that would be awesome.
Thanks
