I came across a heating unit that was installed up side down. The burner area was over the exhaust pipe. Does any one know if this is acceptable on a newer heating unit?

Thanks’

Mark,

I’d make sure your client gets verification of inspection by the local inspection dept. on this absurd installation. I can honestly say I’ve never seen this type of mistake/ignorance in action.

I had told them to have it corrected. I just wanted to make sure I was correct. I couldn’t believe that the installed did it this way.

Thanks’
