I’ve got a kuuma and it like wood in the 15-25% moisture range. Im down to 10% on my stack I have in the basement. The furnace will over temp and set off an alarm if I run the draft controller any higher then the lowest. Although it is nice that it burst into flames without any kindling. Just use the mag torch and in one minute, close the door. Sent from my iPhone using Tapatalk
I'll trade you an Energy King 480 for that vapor fire.....win win! Manufactured in the dells area.....
Furnace. The stuff I’m burning now is left over from last winter before I buried it with this winters wood in my basement. Normally that wood pile is 4 1/2 rows wide and two rows are 9’ high. It’s time to reload with the rows outside. Sent from my iPhone using Tapatalk
I burn wood that is dryer than that. I love that the wood just takes off with no problem at all. I just crank down the damper. I believe my wood goes a lot further when I am not burning water with it.
I have a similar furnace. The moisture content needs to be higher, I think due to the amount of combustion air available. My manual states burn green wood for example. I choke the damper down and it runs fine with dry wood. I do however try to burn hickory, locust, beech and maple that just barely fits through the door. What species are you burning.
Just lower your draft if it's a concern. I snipped the wire for the audible alarm on my Kuuma. It's nothing to worry about. It will happen when loading a decent load on a pile of hot coals from all the off-gassing. The stuff I'm burning is in the 12-18% area and is 6.5 years old. You can also turn the secondary "hidden" pot CCW that will raise the temp at which it sets the alarm off at. It also gives one more heat if needed. I also had to add a washer to my BD in order to pull my draft down.
Forgive my ignorance, but what’s wrong with running the draft controller at the lowest setting if that works for the dry wood? Did you contact the manufacturer? You can’t be the only person who has wood stacked in the furnace room that ends up getting super dry. I would think that an inability to burn very dry wood is a design defect for which they should engineer a fix.
The lowest what...the lowest setting on the baro? Or the lowest the Lamppa recommends? They will flat out tell you to take it down a lil more if you need to...my ole Yukon furnace ran at -0.02" WC. Agreed. Oh yeah, what is it?
The lowest setting on the draft controller. My baro damper is set to achieve the lowest flue vacuum. They recommend .03-.06 and I’m at .04-.05 most of the time. I’m not worried about over heating the furnace. It has protection by closing the draft door to idle mode and kicking the fan into high speed to keep from melting down the reactor. I never thought about holding or weighting the baro damper to get less draft on the stove. Usually my wood going in the basement is in the 18% on average. I don’t need any more heat outta my furnace. I can get sweated out without too much effort. Sent from my iPhone using Tapatalk
I’m burning ash and some oak mixed in. I gotta get the pieces down to 4x6 or it won’t slide down my chute into the basement. Sent from my iPhone using Tapatalk
They officially recommend-0.04 to -0.06", but also say you can go to -0.03" no problem...I'd do it in a heartbeat if you are not struggling for heat! And yes, if the weight is fully out already, you will need to add a lil washer or something behind the weight so that you can run a true 0-0.03" on a manometer. Oh, check and make sure your baro flapper is moving freely too...I caught mine worked over against one side last week and it appeared to be working fine, until I cycled it fully open and closed by hand, I realized it was rubbing a lil on one side and keeping my draft more like -0.05 to -0.06" when I have it set to run -0.04"...and I had noticed my flue temps running a bit higher a few days prior...shoulda checked it then!
That's only when your plenum temps reach a certain point. I think it would take one hell of an out of control fire to ever reach the point to where the high limit gets set off.
