High temps osburn 2400

[dafattkidd]

Also a method I use to avoid runaways: rake coals forward, cut a valley in the ashes from front to back in the center of the fire box, load two large splits on top of one another in the very back, load a medium split on the ashes next to the large splits, place another medium- large split on top of that, place a small to medium split on the hot coals, place another small to medium split on top of that. Leave the door open for a few minutes while it catches (if necessary). Allow time for front splits to fully engulf in flames. Shut down as early as possible to keep temps down but keep the burn clean.

A simpler way to say this is: rake coals forward and load EW, packed tightly with larger splits in the back and progressively smaller splits towards the front.

I've found this to be a great method if I have a large coal bed and don't want the stove top to run up to 800. Hope that's helpful.

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.

A picture would be much more efficient..I need a pen and paper to draw that one out. LOL.

Here is a pretty close example from last night. I loaded the stove around 12:30. Notice the coals are raked forward and a valley is carved in the ashes in the center of the fire box floor. This allows air to flow under the splits from the front of the fire box to the back. The two large splits in the back are black walnut. The smaller rounds in the front are cedar and pine. The stove top temps topped out around 600.

Obviously I didn't fully load the fire box as the outside temps weren't super low, there was little to no wind and the house was already pretty warm. I reloaded this morning around 9:00 am. Stove top was 200 (same as the start temp). House was low 70s in the stove room and 66 in the bedrooms. Outside temps were mid twenties as a low over night and lower thirties when I reloaded in the morning.

I hope this is helpful, because for some reason this post took me forever to put together.

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.

I have about 28 feet. On a cold day I can hear the draft , this morning 7 logs. Coals from night before 15 min 800 and I completely closed at 800. Door gasket looks fine. Just a big draft I guess

I think this morning quick heat up is due to high chimney and smaller splits. Also n/s load. Going to try the varying size in splits and the e/w load on next load up

strong drafts make a big difference on the amount of air pulled through the firebox. Instead of a lazy flame you can get an incinerator

EW will probably help a bit but 28 ft is a long way. I have 15 feet and I hear the draft howling on cold days, too.
