So I purchased an old Hearth Mate wood stove back in the fall. I installed the stove and it ran pretty well for a few weeks. I found that if I ran it with the air intake wide open along with exhaust and an already warm stove I could overfire the stove if I was not paying attention. So running it at 400-500 degrees was not an issue. However, due to the way the unit is constructed, the ash sits in the burn chamber and there is no tray to pull out. Over time the chamber fills up with ash and started blocking the air inlet at the front of the stove, right below the door. When this became an issue I let the stove cool down and shoveled out maybe 70% of the coals and ash to open the burn chamber back up and eliminate all the ash falling into the air inlet. However, since I cleaned out the stove the other day, it wants to run around 350, no hotter and wants to smoke out when I open the door, even if I do it slowly. Once the door is opened, the fire erupts and begins to better draw the smoke out. This was never an issue before. The fact that opening the door seems to solve the problem tells me for whatever reason the fire is not getting enough air and maybe I have to clean out the area around the air inlet better? Any ideas what to look at first?
