gas hot water vent pipe-sooty
Posted by Becky on August 14, 1999 at 17:11:23:
Vent pipe from furnace angles over at a 45 degree to the hot water vent pipe which joins into furnace vent pipe also at a 45 degree then on up straight thru roof/ furnace has not been running. H2O tank brand new and still have black soot coming back down H2o vent pipe and landing on top of tank. Whats the problem? We replace tank, old one did this too. Thought it had something to do with furnace but its not running/summer! Have looked down thru pipe from top of roof with flash lite and see no blockage. Any Ideas?
