My first puffback of the season happened today. I loaded some coal into the sf250, and left the ash door open to get it caught. I left a corner of the firebox uncovered, but maybe I didn't have flames there to burn off the gases. I started poking through my grates from underneath to help clear ash when Whoosh--there was the puffback. All the ash came out the ash door and onto my face. I'm glad I wear glasses. No damage to the stove. Baro didn't pop out or anything. I think all the force came through the ash door as the gases ignited.

I think I just put too big of a load of coal onto it all at once.

Yes, one lesson I also learned the hard way... Never gaze obliviously into the ash pan area at close range after loading fresh coal on.... :lol:

Unless you have big bushy eyebrows that need a quick trimming... :D

Yee Hawwww. I love it when I can see the fire but it will mess up your day when you get it so close it trims your eyebrows and leaves the little bright circles in your vision!!! I had fire come out of my Bucket a Day at every joint and crevice that I didn't even know it had with a puff back.

I checked the baro and pushed open the flap because I could hear a low rumble coming from inside the pipe. I still had flames swirling around inside the stove pipe. It looked like the northern lights in there!!! I had loaded it to the hilt, opened the MPD, opened the lower ash door and then opened the top loading door to see if I could get some more coal in it. I let it go closed and that's when it happened. The little Bucket a Day made a moaning sound and then it parumpfd.

Won't do that again any time soon.

Sure will wake you up! I have shoveled a little too much into the Harman twice this season-so far-and knew I did wrong. Opened the loading door a bit for some overtire air, got a small POOF, no flying ash though. :D
