So, how do you use the plug? How do you re-seat it, if you're keeping the recommended 2" of ash in the firebox?
Does bk really recommend 2" of ash? The bottom of my princess is two layers of brick thick and seems to burn just great with no ashes. Why give up the firebox volume?
To accumulate 2" of ash with Doug fir would take me three months of 24/7 burning. I've only emptied it once this year and that wasn't even a full ash can.
The ash plug seems to seal well and is not easy to knock out of place.
