I have a basic horizontal venting 18’’ away from the house with a Term cap, no 3-5 feet of recommended vertical that it is says in my manual (professionally done, if that’s what you want to call it). I have an inspection setup in a few weeks and was wondering if anyone has had any issue getting passed with this type of setup. I know I have read of sparks being seen coming out of a setup like this, to me that sounds like a deal breaker!
