I'm glad to learn that I'm not the only one who has wrestled with the smoke problem. I have an attached shed to my house so the smoke filled jacket, gloves, etc... stay out there. They are dedicated to furnace service.
Because the furnace is new to me and a learning curve is involved, I too have to deal with the smoke issue. My problem is everytime I go outside to service the OWB I find a few unburned pieces that are smoldering to beat the band. I remove them to rake the ash out and comb the coals a bit. I then put the unburned pieces back in and add to what I think I need to get me through the next 12 hours. The weather has been so unusual this year that's it's difficult to get a handle on what will last 12 hours and have enough coals available to get the fire rekindled once serviced. This past weekend the temps were in the 40's, by midweek, however, they are expected to be below zero. We have had a few of these heat/cols cycles that make it difficult, for me, to know what I need for a fuel load for the day. I guess as I use the OWB, over time I'll know what will work and what will simply leave unburned pieces in OWB. One thing I did late last week was I had some piece that were quite wet. So, I put those on the very top of the new stuff I put in the firebox. It offered me a way of drying out the pieces before any pieces got to the oint of being burned.
