Got my propane
system inspected today. Clogged and pierced tubing, dysfunctional pilot, etc. After a couple hours of work and a couple hundred bucks of expenses, everything's working fine! ...well, almost.
Apparently, the air intake is taking in the exhaust fumes so the heater stops working after a few minutes. "The guy" said that my exhaust pipe should stick out further than the wall (i.e. stick out from the vent) to allow exhaust fumes to leave and to allow air intake.
I told him that I understood but that the original vent was one piece and didn't allow the exhaust pipe to stick out. In a nutshell, I'm not sure he even believed me. I understand that my vent might not allow the exhaust fumes to leave as well as the original vent that had slits from one edge to the other instead of a series of three louvers. But the guy insisted that it's almost possible that it was designed like that.
My options are:
1) Connect a piece of exhaust pipe to the existing pipe and make a hole in my vent so that the exhaust pipe sticks out.
2) Sell the heater since there's apparently a market for those...
3) Just put everything back together and not use it. (Our original plan as we are not planning on using the heater this summer.)
(Am I right to assume that I shouldn't put any butyl tape and any sealant since the vent will become hot?)
-heater exhaust (round pipe in the middle) and air intake (opening around the exhaust pipe).
