Just about ready to install and I was doing a quick overview what will be going down. I have a stainless steel liner and they gave me a Tee for a clean out for in back of the stove, The only thing is I think it is going to be tight to put that in back. I've been told it is not nessary to put in, But me being anal and not trusting the dealers all the time, can I just attach the stainless to my exhaust pipe. I'm just wondering about ash and fines. It's a full reline by the way. Thanks!
