Not getting a complete burn on my Greenfire

Trzebs,

Check the flex pipe (combustion air) that goes from the damper down into the ashpan. Mine had pulled out at one time.

edit: I was writing this before your last post...

I would be surprised if you didn't, unless Mark changed the design. Mine was one of the first ones made... I have 4 inlet holes in the refractory and five flex pipes in the back. The middle flex pipe goes to the ash pan, letting combustion air come through the grates. Easy enough to figure out with out taking unit apart. pull ash pan all the way out and see if there is a hole in the back of the boiler (above ashpan).

My input may be of minimal use . . .

I thought I heard you say the CC was 'empty'. On the GW that means there is (guesstimating here) 4-5" below the bottom of the air inlets. If you only put one load of wood in and the coals are up to or over the inlets, why are you putting more wood in? Again, you guys running closed systems have some intricacies that I don't understand but on my unit, a fresh load after cleaning the CC will leave basically no ash and no coals! This is the hardest time to keep up with the unit in my experience. My unit needs ash -unlike the operator, who needs _ _ _ - to function correctly. The trick part is being able to move the coals to the back, rake the ash, and do not reload until the water goes below 170 °F LOL, 'course that is easy to say when the temps stay 20 or above . . . .

Everyday, sometimes twice, I pull the ash back from the air intake.
It has to be clean. I've got a 'backdoor tool' to make sure the tubes are clean thru.
Get familiar with it.

i burn alot of pine when its warmer out but when i do burn hardwood and the coals build up i either let it burn down on its own or fill it up with dry pine and let it rip. that gets rid of any coal build up for me.

1) CC is a b!tch 2 heat. Don't try to raise temps more than 1 deg at a time.
2)Shoot for 3 loads a day (possibly 4) In my unit, loads big enough to go all day on 2 will create huge mounds of coals.
3)Do not add fuel until coals are completely below air inlets.
