You are experiencing either a cold plug or a newspaper plug. Burning lots of newspaper in the last cleanout is asking for a wad of blackened paper in one of the bends collecting lots of water. Sorry Max!

Peter, I agree. I believe the vertical stack was hovering around 65 f or higher, compared to 55 f ambient indoors. Unfortunately I wasn't paying attention while we burned all day yesterday what the temps were. Oddly we don't usually get smokeback failure even when the room warms.
Thanks again for the help. We're going to be away from the system for the next two weeks so I'll update upon our return.

Peter. Thanks for the plans, most excellent.
Yes. Chimneys can be larger diameters as the heater, not smaller.
You're welcome, I do sincerely hope it will solve the heating problem.

Agree. In these specific circumstances I'd think it will work.
Matt Walker wrote:Well Peter, you touched on most of my concerns. Insulating all around the flue would go a long way towards alleviating most of my concern, which is that the giant heat sink of the ground around three sides of the flue is going to keep that flue too cool to work well. Condensation and chimney stall will be constant instead of a seasonal hump to get over by warming the mass. Less surface to radiate into the space is another issue. It may work, but I'd be surprised if it isn't a constant battle.
