New question... chamber not staying at temp
« on: January 26, 2014, 08:10:16 AM »

So...  my quest to figure out the temp discrepancy is on a brief hold as I try and remedy another problem.  (but I think it is that my indoor gauge was just off a bit) 

I have had this problem for the last few days...   Put wood in in top of a hot coal bed.   when I shut the door, the temp races through all 3 stages...  up to 1300+ degrees...   [I get excited] then it slowly ticks down...  and settles around 435.  It does not always go as high as 1300...  sometimes 950+   but it always peaks... and then settles back down to 435 after about 20 min... [I get sad]  the water temp is never getting higher then 165ish. 

When I open the door to check...  with in a couple seconds I have a roaring fire...  shut the door and the bypass... and who thing repeats... high temp then settles back down around 435. 

This has been happening with All Oak, All Pine... or a mix of both.  (I thought maybe I had bad wood, so I have been mixing it up)   All wood is seasoned.

My thought is that it is not getting enough air when the door is closed and the bypass door is engaged...   But I have cleans all the solenoids, checked the air holes in the fire box... etc.

thoughts?

thank you!

Sure sounds like a lack of oxygen issue. If you open the door and she fires back up, burns hot and then comes back down it sounds like a ventilation controlled fire. Check everything all the way from where the fan blows air in to the flue pipe for restriction.

Will do... thanks Hondaracer.   

I will say... I redid my goal bed and it seems to be getting a lot better.    Although my Pine is only getting the combustion chamber to about 750 degrees consistently.. but that might be the nature of Pine? 

I am starting to throw a couple pieces of Oak in the bottom when I fill to keep the coal bed nice and hot... and then Pine on top.   And it seems to keep it going better.

Living and learning the ways of my OWF.

of course I went into the basement this am and found water...   result of a broken water pressure gauge... water was coming out of the back... weird...   8 dollars later we are back up and running.   Always something!

Thanks for all the help...   Hopefully I can get through this week and give the system another
 good cleaning this weekend.

I would do the self diagnostic check  you can put it in that mode where it runs everything opens solenoids runs the fan etc.   are you familiar with this    I would try this and watch solenoids just to make sure it's everything is working correctly

Boy I wish my E2300 had some of these luxuries you guys are talking about.  I have to open my combustion chamber to check my fire/gasification.  No fancy temp gauges to go by.  That being said, I've been there with this problem  PMo.  This haunted me for a few years.  Really sounds like restricted primary air flow to me.  I'm not familiar with your models design or how easy or hard it is to clean out, but that is, in my opinion, the root of your problem.  Clean all the outlet holes, and make sure the tube(s) is/are clear and that the solenoid is functioning properly.  I would think that should take care of it.

The original E2300 had no way to clean out the air channel.  Mine plugged right up full and was a nightmare to keep running.  I ended up ripping out the old channel and replacing it with my own pipe assembly which is removable for cleaning.

Hope this helps.

Thanks for all the suggestions everyone...   such a great resource this site is.   

So I cleaned the thing from top to bottom today...   to my disappointment, there was no real blockages anywhere.   

I re-did my coal bed with oak and burned only oak today... thing worked like a champ. 

I think the root of my problems was the wood... I was burning a lot of pine... that was "seasoned" in log length...  and then split just last friday.   I was having huge problems keeping a coal bed the last few days... climaxing to a NO FIRE this am, but 3 full logs that were clearly on fire at one point. 

Burned oak today... and presto...   of course I did do the full cleaning...  so for now...  I will keep it clean.. and burn oak.   

Thanks all!

Wood can be the culprit of a lot of problems for people. I know that sometimes I will have a problem getting a load of wood to burn well and it usually has to do with moisture content since I burn only hardwood. Pine that is not split can be ridiculously full of water. I had some pine that I left for a year like that and then tried to burn it, it wouldn't burn.
