Posting this to a separate thread to keep stove-specific threads and/or rants about VC from polluting this thread: Here is the procedure that I follow once the stove (Dutchwest 2479 everburn) is up to temp and needs to be reloaded: 1) Open bypass 2) poke residual logs to collapse into coals (if necessary). Needs a good 2+" of coals, so plan accordingly 3) load fresh splits (see note below on orientation) 4) open air inlet 100% for about 10-15 minutes or until fire is very active (about 475 on the flu connector magnetic thermometer) 5) Damper down to about 1/3 air and let burn for another 10 minutes. This reduces wasteful burning that is just rocketing right up the chimney, but is necessary to pre-heat the new splits on the top 6) Open air inlet to 100% again for about 2 minutes to get an active fire again 7) Close bypass/engage everburn. 8) If rumble persists, temps are good, smoke-free at the top of the stack, I damper down to about 3/4 then 1/2 then 1/4. If the everburn "stalls", it means that the coals werent oriented right, there weren't enough of them, or the fresh splits were 'ready' for that stage yet. All the above assumes dry, seasoned hardwood. Also, I have a thick masonry chimney which has to be properly heated before it drafts well enough to use everburn. This takes about 2 hours in my set up. Also, when the drafting is good and outdoor temps are low, lately I've been experimenting with the following to reduce 'thermonuclear' incidents. A freshly loaded stove holds about 6 medium sized splits on top of the coal bed. I have been putting two less-seasoned splits on the top row. That way they bake for a while and dry out before the splits below them reduce to coals. I dont mind the extra energy required to heat the water in the unseasoned splits because this stove throws more heat than I need when everburn is working properly.
