I've heard that coal is the way to go but I'm having trouble believing it.
welcome to the forum bub. hmm, does the fire go out? let us know what your set up is, paint us a picture. whats the dampers set at? you have a barometric damper? what is everything set at? and the biggest thing im thinkin right now, are you loading the coal high and deep? make sure each load you throw on as much coal as you can. right up to the top of the fire brick. my hotblast says 70 pounds but their are days (like this frigid day) i will put in at least 100
