I'm really glad you are ok. Good call on 911. This scenario has happened before, even to some pros. It's easy to get distracted and forget about the fire. I strongly recommend getting a clip on kitchen timer that has a persistent alarm. Set it for 10 minutes after a reload and clip it on you. This has saved me multiple times. Note, we've seen clogged stacks happening in a month here. It all depends on the wood, the flue, outside temps and how the stove is run. Your setup looks ok, but have it checked. Note that this is why we insist on safe installations. Chit happens. The flue system did its job and protected your house and family.
