Do over fired stoves smell from outside near flue

So I have a new insert with 6 inch flex steel liner. Love it. I'm real careful to watch the flames so i know I'm burning properly ( no smoke, lazy flame, secondary burns here and there ) I don't have a thermometer no idea where I'd put it.

I had a full load of white oak and it over fired ( looked and felt that way anyways ) for about 7 minutes or so. I simply shut the air off, the insert started to cool off, I heard the metal ticking as it cooled etc. All is fine, flame went back to normal.

But I went outside just after and there was a funny smell in the air. Not bad smell. Not burning smell. But different. I'm assuming the exhaust coming out was much hotter than usual. Smelled odd. The insert is fine, nothing's changed.

Any thoughts what the smell was ? Any reason to be concerned ?

Thanks for the replies.

So I wasn't probably over firing then ?

It just seemed really hot and ofcourse the flames were huge. And then that smell i described but only from outside no smell inside the house.

I accidentally left my primary air valve open is what caused it. Then I walked away and got distracted. My start up valve was closed though or else it would have been over the top too hot.

Well thanks again I won't worry about the smell .
