I've always had poor draft. I imagine I've got the stacking effect working against me, but you never know. I live in a chalet style house with the furnace in the basement and a 25-30' chimney. Chimney was cleaned, new piping, etc at the beginning of the wood burning season.
Question is, do I NEED a flue collar, and/or will it help with better draft? My piping goes directly into my concrete wall and I've sealed it up with the Rutland 800 degree Latex goop. It's since cracked, and I've been considering ripping it all out and applying some red RTV in it instead or something. I've tried 2 high temperature sealants, and both have cracked and separated at that location. RTV can't crack.
The way my setup is designed, there's no way I can fit a flue collar on there unless I custom cut or fit one, as right above the hole into the concrete, there's a bar that runs into the wall also to secure the piping to the wall.
Worth the time, or just seal with RTV?
