Is tape ever used to seal the seams of a WH or furnace flue? If so, is it something other than the metal tape used to seal HVAC ductwork?
I'm asking because my home's WH has a 3" single wall that is poked into a 6" single wall that comes off the furnace. The 6" goes into 6" B that goes up and out the roof. They sealed the 3"->6" connection with metal foil tape that looks pretty sloppy.
