Let me first say,I have a Harman tlc-2000 wood\coal stove. I had the strangest thing happen last night while loading with wood for the night.. I had a solid bed or coals going [all wood, not coal], and loaded it up with splits of oak for an overnight burn. I had the ash pan door open and wood air contols open to get the fire cranking before closing the dampers down. The coals were not igniting the wood, it was strange, it just kept smoking; about a minute of this and then a loud WOOSH!! it ignites all at once. Scared the crap out of me..a huge puff of ash shot out the ash door[which was open]. I've heard of this happending with coal, when all the coal gases ignite all at once; Has anyone experieced this with wood? I never have, it was very strange..
