Last night in the middle of a burn cycle, I opened the door to top it off with wood.  Fire was roaring pretty good and there was a flame just like you see out of a jet fighter afterburner coming out the top of the flue pipe.  No roaring or noise.  Was this creosote burning off??

It was cool!!

I call it chimney cleaning. Good point, It would be nice to recover that heat.

could be some creosete burning off but more than likley if it was near the end of a burn cycle the fire was going good and had the chimney hot and when you opened the dorr you supplied enough air to rush up the chimney and ignite the gasses i the chimney...you need "heat' "fuel" and "oxygen" to have a fire..you have both when you have a good fire going but in the chimney you don't enough oxygen to fuel the fire, until you open the door and the air can be drawn in, in the amounts needed to ignite this gas in the hot  chimney.

Must be what gassers do.

Sounds like a good old fashioned creosote burn out of the chimney to me.
Did you happen to have a good wind blowing in through the open loading door at the time?
Not sure about your gasser comment. Your CL5036 is not a gasser. That is a traditional model.

He just meant that a fire like that must be what gassers are able to do all the time


I think

Yes. That's what I meant.

Unless it throws embers onto something flammable like my house, or woodpile. Noooooo.......

I actually had that happen with my CB E-2300 (Gasser, by the way) a few times my first year burning.  Only happened after having the bypass damper open to add wood during a high demand time when there was a roaring fire going and I was just topping off the load.  But a couple of times it stayed burning out the chimney even after the bypass damper was closed.  Come to find out the bracket that holds my damper in position was too weak by design and wasn't holding the damper in the right place causing smoke to leak out and creosote to form around that area.

That is very similar to the way a gasser burns.  It is a very impressive sight looking at the torch-like flame coming down into the combustion chamber of a gasser.  It's not much differant than looking in through the sight hole of an oil-fired burner.   I'm sure there are other videos out there, but there is a good video of the P&M Optimizer 250 on youtube.  Worth checking out if you've never seen one.
