Well, believe it or not I took an empty can such as you find in the
supermarket filled with green beans and cut off the other end (both ends
removed) and used that to go over the vent on top of the water heater,
and attached it to the duct that leads to the wall. I don't remember why
I had to do that. Maybe a section of the duct had broken or worn
through. Anyway, the duct tape I used to join all this together has
never given up the ghost. It's tight and hard at this point and it's
charcoal black.
