Hot water heater flue vent connection

Yeah, I know it’s not a hot water heatr, but I like to see who reacts.
Is it ok to use aluminum foil hvac tape to connect the vent pipe to the top of the heater? I don’t have a picture of the finished product, but here is a pic of the problem. The pipe pulled loose, and they stuck it back in place and wrapped it with tape. Seems to me that the heat would cause the goo to breakdown pretty quickly, and then the joint would open again.

Note that the flue pipe in question is galvanized (as req'd), not aluminum. That should answer your question.

Why didn't they just raise the WH up a few inches? A stack of old, unused code books probably would have done it. ;-)

Obviously there's more to the story. The heater is in a finished basement. It was moved by non-plumbers who were doing other work in the basement, and they did not reconnect the pipe when they were done.
I kinda figgered that the goo acts as a dielectric break ... :)

Can you dumb down your response a bit for those of us who don't know what you're getting at?
Madness takes its toll. Please have exact change.
I think since FastEddie asked if Aluminum tape was ok, MikeHennessey said that only galvanized pipe is ok, therefore aluminum is a no-go
O.K., I believe ya. But why?Not trying to stir up trouble - Just trying to learn something.Even us good lookin' rednecks don't know EVERYTHING.(-:

Don't have a book in front of me -- it's under my water heater ;-) -- but I'm pretty sure code specifies steel, stainless or galv, for flue pipe. I assume because Aluminum will melt/deform at such a low temp and quickly corrode from the flue gasses.
I didn't write it, I just do what the inspector tells me & smile!

3 sheet metal screws.
I was told in the past 2-3 days by a Home Inspector that tape is NOT allowed on flue pipe joints.
