I think the standard answers are: 1 loading N/S. However, I have a shallow firebox in my insert so that is not always possible; 2, Use the andiron. However, My insert only have one door so the andiron get in the way of loading and shoveling so I took it out often. Then ash will get into the andiron socket and will accumulate there. The andiron can become wobbly and it may be wobbling so much to hit the glass itself, which is even worse than log hitting the glass. Any other way?
