Hi, I run a wood stove, burning clean logs as far as I know, and this year the stove has started to give off a plastic-type smell when it runs super hot. I was a bit concerned about this but thought maybe it was just paint overheating.

Then tonight, after running the stove hot for a few minutes to set it up for its overnight burn, i noticed the chimney cap was glowing red and small sparks were coming from it. Cooled down rapidly after I closed down the vent on the stove. The fire had gotten very fierce before I closed the vent.

Did I have a chimney fire? I cleaned the chimney myself in November. First time I've done it but it seemed good and clean after. I've never seen the cap do that before.

Any advice? Many thanks for your help! This is only my third winter with a wood stove so I am pretty new to it.
 
sounds like a fire is definitely possible. check the flue - if you did have a fire the creosote will either be expanded blown up looking or it will be all gone and flue with be sparkling clean. check for damage/cracks too!
 
Glowing red cap and sparks coming out of the chimney . . . while there is a possibility that some errant sparks may make their way up the chimney (a relative slim possibility) combine the sparks with the glowing red cap and I would say there is a very strong possibility that you had a chimney fire.
 
What's you setup as far as stove, chimney and wood? New to you?
 
I assume your stove has a bypass damper? Stoves of this design are more likely to have small flue fires, since flames have a direct path to the flue outlet. Definitely not a must to spark a fire, but more common to see these little short lived flue fires.

I've had my cap do this before, it barely had a film of build up, but was able to ignite and then burn out as quick as it caught.

Yes absolutely a chimney fire. Inspect everything well before burning again.
