Overnite sucess A couple days with the stove running, and after 8 hrs of unattended burning, once again I awoke to a "relatively" good fire. The stove had cooled down to about 250*, but still had a good portion of the coal bed still visibly burning. the draft was about -.04, and with a good scraping, poking and refueling, we're good to go this morning. Didn't do any major adjustments before bed. MPD was "almost" shut, and my thermostat was up around 2. (A tad higher than usual.). I also M/Td the ash pan B4 bed, even tho it was only barely 1/2 full. Am wondering if this has any effect on primary air as the stove runs thru the nite. Anyway, it's Fri now, 1/2 way thru my winter vacation. Also have all next week off from work, so it will be interesting to see how the stove performs on a daily examination. 20* outside, and a rising 70* inside.

Yes, Its evident in some of the pictures. Look at this one below.. Blow the picture up and look where the arrows are pointing. See how its dark there on the fire box wall? Fly ash is not settling there.. This tells me your primary combustion air IS being routed between the coal bed liner and the fire box wall.. We don't want that. Your primary air is bypassing here instead of up thru the grates and starving the coal bed as ash collects on the grates. It pins the symptoms you are seeing.

Yes, fiberglass will take 1200 degrees. I have some tucked around my coal bed liner. It lasts all winter.

Excellent!! Lets see how things are going in about a week or so. If your fire starts to die again before 8 hours, I advise the fiberglass seal around the coal bed liner. :D

That will be the test. How it will last after a weeks worth of ash build-up. I look fwd to the experiment. I'm also curious with my new technique of riddling and poking with the glass door open, to lessen the draft and prevent fly ash from heading out the pipes, will hopefully keep the stove and system cleaner. I'll have to admit, I did order an RC field baro-damper, which will come next week, but it'll be the last mod I'll do.

If you do decide to seal the liner against the fire box wall with the fiberglass, you'll wanna do the entire perimeter around that ledge I pointed out in a previous post. Take some pictures during the task :D

The small panes of glass were there, from what Ive read and been told, to allow some of the heat to escape. I think it was 2 or 3% more efficient with those panes. A person would think they would allow some air in too. Mine had them when it was new but I replaced it with a solid piece. I have no real opinion which way is better (but I like the looks better without) but I knew my panes were warping as I burn some wood in it too, so I went with one piece.

I know my stove throws more heat out those panes of glass, than any other part of the stove, including the heat exchanger.
So warmin, you were able to fit a single piece in yours? Is there any special glass needed for the heat, or can it be a piece from any hardware store?
Lee, next time my stove goes out, I'll jamb in some Owens/Corning and shoot you some photos. I'll be able to do 3 sides, but not sure about the front of the box where the door is. It'll be interesting. Thanx again for the tips.

Yes, I put in the single piece. It is a special glass I had to order. Wood stove glass wont work. I cant remember what its called but if you search for glass on this site you will find the name. I think its the 3rd year Ive used mine. Like I said, I have no opinion which is better. I just didnt want to keep warping the thin panes while wood burning.

Im looking forward to your results with the fiberglass and hope it solves your problem. Just keep pegging away at it and you will find your problem. It has to be frustrating. I tried many, many things and ways and it did pay off when I found what works for me.

Sorry to butt in but are you saying your running the stove with openings in the glass ? 2 missing thin panes.

Im not sure if you are asking me or joeq, but if me, I have one piece of glass that covers the whole door, instead of the panes that it came with it new. A lot of the Euro stoves came with many slim pieces of glass in the door instead on one large piece, like American made stoves have. There are slim gaps in the Euro door glass pieces.

welcome aboard Lewis, and don't be sorry. The more interested and participating personal, the better. I wasn't saying I was running my door with missing glass, just that the single panes "theoretically" allow air to pass thru them. (between the cracks.) Do you have good success with your Nestor Martin?

Went to bed at midnite, and needed a morning "trickle" at about 5:30 am. Coal burning good, so I gave it a quick riddle only, and went back to the sack. the girls got up B4 me, so I'm assuming they did a little scraping and refilling, so can't accurately say how long the fire would've gone. we've been home off and on thru the day, but the coals have been going fine, with little tending. The temps did go to almost 50, but tonite we're back in the high 20s.
Lee, you asked quite a few posts back about a lever on the frt of the door. I didn't see what you meant until just now. The lever is the one that locks the door shut. You can get a good view of it in my reply just underneath it.
Tomorrow I'll be heading to Boston, to visit my son, so I'm assuming my stove will be out when I/we get home. (Probably about 12 hrs gone). At that time, I will clean the stove of all ash, and stuff some insulation around the skirting/liner, and see if that cuts down on any "secondary" air. Unfortunately I will also be gone the 31st, (my birthday :( ), till the 1st, so once again, the stove will go out. Tough to learn this thing, when I have to keep leaving it. Out for now.

Ehh,on the bright side,you'll be able to incorporate your mods and see the results bringing it back on line. They seem to make good sense to force that combustion air up through your coal bed. Thanx for this excellent Thread ! :up:

Hi joeq, I wanted to mention that franco b said your stove has drilled holes somewhere in the front of it for a fixed secondary air contribution. This is a good thing since it should get some secondary air. The fiberglass seal will simply prevent any of the primary air from routing around the coal bed and becoming more secondary air which is the result we're looking for.. :D

Have a safe trip and Happy Birthday!! :happy:
