Termination of furnace vent

[Gerald C. Wilcox]

Power vented furnace terminated underneath a deck. The termination was 5ft away from opening slider panel on glass sliding door and 5 ft away from an opening window. If I remember correctly that was an acceptable distance. Is that correct?

Thanks Larry, I was thinking it was 3 ft. The fall colors are probably well over by now I suppose.....I lived in Alpena, MI for about 14 years, you know the wrong side of I-75. Used to work for a fellow that owned Great Lakes Pipe and Supply. We had supply house's in Petoskey, Gaylord, Alpena etc.
