High temps osburn 2400

[Sully]

I've been reading different post on how to modify primary air on osburn stoves. I have not tried it but have def been thinking about it. With only the one air control I feel like there is almost no way of getting the fire to burn slow. I've seen temps go up 350 degrees once air is shut down. Unless I close it down at 450 it's 800 degree burn every time. I don't get it. When I load stove full if I let all the wood char the fire is burning so hard that I can close air completely down and see almost zero change in the flame. I rarely see the lazy flame. Just wondering if anyone else has this style burn

800 degres is on the high end of where you want to be, but acceptable in my book.

How long can you go between full loads? How are you running your blower?

 

[Sully]

I try to go at least 8 hours between loads. Blower is on automatic and set on low setting.
Stove does great job of heating, I'm just curious on a way to cut the air back more to make it not such a giant burn. Seems like 300 is a lot of a climb after I shut air down

Where are you measuring the 800 on the unit?

 

[Sully]

On top towards the back

Hmm, 8 hours between loads on that unit doesn't sound too bad for the unit though.

I guess I'd be looking at trying to slow that down a bit too as 800 for each fire does seem excessive, however, I don't know the specifics of the osburn enough to direct you there.

The 8 hours is just what I'm trying to do. Let it run in cycles. To effectively heat house it is less than that but it than starts to accumulate to much coaling and is sorta pointless to me because loading half the wood. It's a 3.2 fire box and I've gone almost 16 hours and have been able to light new fire of coals. The stove is awesome. Everyone says it likes to run hot, I'm assuming they mean the temperatures I am getting. Would be nice to be able to control the inferno a little better. When it's going there is no way to slow it down

Hmm, well if that's the case, then limiting your air would actually increase the amount of coaling you are getting.

If I really need to run the stove hard to keep things warm, I wind up needing to open the air control up fully at about 2:30 or 3am for a 5:15am reload if I loaded things up at 9pm.

That does seem hot, but I'm afraid limiting things might give you other problems from what you describe.

Sully- not sure if you figured anything out - and I just got this stove this week, but I have found that with my air closed all the way down, I don't get the climb you have. It sounds like maybe a second air leak somewhere. Could be the gasket, or the holes for the over lay. You could also take a bit of fireproof insulation, and put it in the front hole to see if that helps blocking something. I got a good 12 hours of a burn, with some coaling but what was left was perfect for me to relight with no real issues.

I difference in chimney setup, as well as wood of course, could also make a huge difference in performance that one user can have versus another.

My 2300 cruises around 700+/- 75 degrees.

As Pen mentioned, too many coals is because the primary is turned down very low. Personally I NEVER load my stove completely (jam it solid). It just goes too nuclear. I usually load it to just above the fire bricks and can reload after 10 hours which is fine by me.

My Napoleon ran really hot too. I found my wood was very dry and I had a tonne of draft. Recently my wood has been soaked due to weather conditions, however not wet like unseasoned wood. Also I installed a flue damper. The combination of these two things made all the difference in the world. First my burns last longer and second I have fewer large chunks of coal. The flue damper really helps when it starts taking off even after you've closed the draft. It stops the temperature rise dead, and and the stove will only rise a bit more then cruise away. I tried all the tricks (blockIng sections of the primary and secondary) but nothing had real world results for me. I really think 20% moisture is perfect for my stove, but the 12-14% that my wood is at made it burn very fast and hot. I checked my door gasket, and baffles. Being a simple stove I don't have a lot of gaskets to worry about.

Have you checked your door seal? When flames are good turn out the light if you see flame flicker where the door seal should be sealing your sucking in air, a common problem with these stoves. I run my 2000 between 600 and 800 and love it , if your doing yjis with your blower on low move it to medium ! Ive got emails from SBI claiming 800 is ok , but i wouldnt go anymore than that lol

I tend to run 600-700 range. There was a cord of super dry oak that would take off every load just like sully is describing. But with that exception I can usually keep the unit below 750. Sully, forgive me if you told me this already, but what is your chimney height?

Also worth mentioning I often cut back the air to about 1/2 at 250 if I have a good char going on a decent bed of coals. Then cut back all the way by 450. Then I leave the fan off until it climbs up to around 550, then I turn the fan on low. I like to operate my fan manually.

Just in case I missed something here, especially since this is an insert, where is everyone taking there temp measurements from on the unit?

A difference in where the temp is taken can make a huge difference in explaining what's going on or explaining what should be happening.

Just want to make sure everyone is on the same page.

I see so many of these insert posts about trying to control the fire.

Ok, what's your point?

 

[Huntindog1]

Seems like there are more variables involved in an insert situation.

The 2400 has a good surface area on the top plate to keep a stove top magnetic thermometer.

 

[etiger2007]

I take my temp as fatkidd does, its called out in the manual that way!

 

[Alan W]

could also be a difference in the models. I do have the 2400 insert, and although its new, I don't see anything running away. When I close down, it slows right away. The unit does run hotter than my past. I do not have any thermometer but I can boil water if I fire it up. But the concern was it not shlowing down when cutting the draft, and I do not see that issue at all- but I also note that the knob on the draft, could be set too far in, causing the draft to not fully close.

Only been running my Osburn 2400 for just over a week. Installed on the 19th all I can say is what a great stove! ! What a great monster! So your saying the Draft control does very little on your stove wow. Mine goes from a full blown inferno to a lazy fire. Keep in mine with a full load there is still lots of flames cuz the secondaries are going full bore! If you would like to see the difference I could post a video of wide open vs closed Draft.

yes - when I get home, clean things up and actually put the face on.

Here is a video of my Osburn 2400 open Draft vs closed Draft. Not very cold out so I only have half a load in there.
