Venting Jotul QT - Hearth Installation

I would insulate and see if that works before extending the chimney or buying a fan.

Have you thought about pulling the stove out some and installing a rear heat shield so all your heat doesn't get absorbed by the masonary? I think you would notice a big difference in heat!

I don't know too many tripple or quad EEEEE widths Little humor here nothing more than I read your post

Point being there has to be enought verticle hight for smoke to develop momentun. Restric the flow, elbows or change in direction one has to add to the verticle height to allow momentum to be built up again. If you should need help with Math formulars or lineal equasions, I can not help but would call on my three brothers to smooth over the interpetation. One PHD MIT U Pitts and dean Chemistry. Secomd PHD Math Math Carnigie mellon Working some where in the Pentagon. Third Phd in electrical engineering
Me working on my PHD in English and have a long way to go. but a sense of humor

I'll give the liner insulation a try.. At the least, I should have drier wood on my side.. The wood that I used last season seemed not to be quite ready for prime time.

I suppose that if nothing works, I can resort to the fan.. I'm not crazy about having to introduce mechanical ventilation into the picture, but at least I would be assured of getting a good draft.
