1800i floor protection width

[EbS-P]

I am trying to figure out how wide my no combustible floor protection needs to be. This is for a raised hearth >5”. I’m trying to get insurance and they will inspect my diy install. That currently only has 11” of hearth. So I need to extend to floor protection 5”.

Your looking at dimension M and N?

I think so I’m really sick and am have a difficult time reading these. So M if for USA and its 8” beyond both sides of the door? m is for Canada

I’m still trying to figure out why there is an M and N, they both state 8”. In my post #2 the diagram looks like a face on view based on the brick they are showing yet they have a circle shown that I’m ASSUMING is the flue? The door detail looks to me like it a Birds Eye view. Confusing for sure. I’m sure someone smarter than me will be able to help.

Hope you feel better soon.

If possible, exceed requirements by a couple of inches. It's better protection and helps defer concerns.
