Hi New here, can’t find ‘post new message’ button but my question is about Heatilators so I hope this is okay:

We had a Pacific Energy insert installed in the 1970s era Heatilator that was in our old masonry fireplace. The installers put a flexible SS liner down the old clay flue and connected it to the insert. Our masonry chimney fell over due to so much snow this winter. We would like to replace it with a modern round insulated SS chimney but the guy who installed the insert said there is no way to do this - we have to have the outside chimney rebuilt with a clay flue and then have a new flexible SS liner installed in that. I just wanted to be sure there wasn’t a product out there that allows a rigid insulated SS chimney to be mounted to a Heatilator that has a wood burning insert.

Thanks!
 
@marcospeechli, I created a new thread for you. The big orange button is at the upper right of the page.
There are adapter plates that can attach class A chimney to a stub of a masonry chimney if there is still one left. However, there may be complications that make this hard or impossible that the installer is seeing. Can you post some pictures of the chimney?
 
Thanks Be! Pics attached. Unfortunately there isn’t one showing a clear pic of the top but hopefully you can get the gist. You can see the flexible liner coming out of the top of the stone. We were thinking of demolishing the chimney and converting to a through the wall SS fitting and insulated SS chimney with siding behind. Plan B would be keep what’s left of the chimney and adapting to SS from there up. The main reason we want to get away from liner-in-masonry is that it takes a long time with a space heater blowing right into our Pacific Energy insert to heat the chimney enough to get convection going so we don’t fill the building with smoke when we light a fire. The second reason is that snow that collected behind the chimney melted and leaked [Hearth.com] Broken chimney on 1970s Heatilator through our standing seam steel roof.

Any ideas gratefully received!
