Secondary Burn

[billdad1]

I have a Jotul F3CB and have not used a stove in years.
How do you achieve a secondary burn?
How do you know when you are getting it?
What steps do you take to maintain it?
Any tips would be greatly appreciated!!

Feed the stove dry wood, not too big splits (about 3-4"). When they are burning well, close the air back about 50-75%. (The amount depends on the strength of draft.) Enjoy the show for about 30 minutes.

BG,

what happens after 30 minutes? Does the absence of secondary burn indicate incomplete combustion? It's not to the coal stage yet.

This is a small stove. tutusue, myzamboni or bbart may be seeing longer secondary burning with hardwood. I didn't get long secondary burns with softwood in the 1 cu ft firebox.

If the upper part of the stove is hot (1100+F) and there is no secondary combustion it is because all the volatiles are being consumed by the primary fire.
