The secondary air feed at the top of the firebox is igniting the gases coming off the wood, creating a blue flame. This gives a more thorough burn, generating more heat and less smoke and particulates from the chimney.
Incredibly, these blue flames are coming from tinder dry balsam, generally considered a low caliber firewood. (See blog a few postings back)
To get the blue flame you must first get a hot fire burning, then check down the draft so it is only open a smidgen.
Half an armload of the balsam keeps the sunroom cozy for about six hours.
We should get even better performance when we burn dry birch next fall.

Dan: With that very nice new sun room and the addition of the Napoleon Banff 1100, wood burner, a person could be tempted to spend a lot of time in there, and maybe
just maybe catch a little nap.
Enjoy

It is tempting, very tempting.
Here's a really neat thing about the sunroom: in the heart of the winter -- when the sun was lowest in the sky -- the temperature in the sunroom would get up to 28 C (82 F), just from the sunlight. Now that spring is here (as far as the sun goes anyway) it only warms up to 24 C (75 F) since the sun is higher. By summer it should be one of the coolest places in the house since the sunroom is on the south side and the sun will be on the north side.
