I recently replaced my cracked door glass in my whitfield II. Since then, my ash seems to buildup around the burn grate alot more and much less down in the ash pan. Otherwise it is burning just fine. Having it sealed up better allows me to keep it burning on lower settings when needed. Thanks to many Hearth members who suggested I buy ceramic glass instead of just tempered. I did and I'm happy for it! Have been burning American wood fibers all year. Best pellets I can get locally. Others are Presto-logs and Penningtons. Anyone have a remedy for ash not falling into ash pan very much?
