Hello, I've been researching to build my own gasifier for 3-4yrs now. I've studied them all. Indoor & outdoor, small &large, popular names & the uncommon. I've learned from forums to avoid a CB OWB. Most negativity originates with the old style of non gassers. I watched your vid and found it interesting because, I was interested in learning it's construction. You've given me a clear vision of why I would absolutely not want one. The maintenance procedure purely sucks. Since these gassers require more maintenance, the ease of it is a must. One thing I can point out is, the dryer your wood, the less creosol you will have. In my boiler research I have learned something on reaction chambers. Line the steel with ceramic blanket and or firebrick. As long as it doesn,t interfere with your bypass. If I had your boiler, I'd get conventional woodstove fire brick, line the floor and sides. Possibly a rear wall or a full U shaped area, around the factory refractory center piece. Forcing the gasses toward the front before they can exit the rear. Transferring the heat into the brick will help faster lighting of the secondary flame, between cycles. It will also help force more heat through the stoves heat exchangers. 😉

Thanks for sharing what you've learned. I don't have anything to compare mine to, but all-in-all I'm satisfied with it. Had an indoor wood boiler prior and I much prefer an OWB to that for many reasons.

@@timberterra Me too. I'm building an outdoor.

Where did you get the brush to clean the heat exchangers? I have the same boiler, and that looks like a much faster way to clean them.

Wood furnace world. I think this is the part: www.woodfurnaceworld.com/products/kit-flue-brush-m250-m255-ecl-e-24 I replaced mine a couple years ago and got it from my local dealer - brush only, not the handle. I didn't like the fiberglass handle it came with. I made a rigid handle with 3/8 pipe.

@@timberterra Thank you! I will give this a try.

What moisture content do you require your wood to be before burning in your boiler?

From what I've measured, it is normally just under 20%. I'm finally getting a year ahead on my wood, so it's probably closer to 15%. The first year I had it, I spent my time installing it rather than getting wood ready, so I cut up and burned dead standing trees. That was probably in the 20's. A noticeable difference.

@@timberterra Thanks for the reply. I have a classic edge 750. I burn wood that is between 15 and 20% MC. I am having trouble with proper burn after loading the furnace with wood. I load the firebox less than half full in the morning with a decent coal bed. Quite often the fire will smoke itself out, and I will return to find the 'fire out' code. Sometimes the water temp drops to 90. I have cleaned everything just as you show in your videos. Sometimes I try leaving the bypass door open. That kind of works, but it seems like it just needs more fresh air. Once the wood has smoldered enough it will eventually gasify, and I will get reaction temps of 1300. Dealer didn't offer much advice.

Sounds like it's air-related as you mention. All your critical airways are clear? When I burned wet wood, the reaction temp would seldom get above 1000F, but I didn't have issues with the fire going out.
