I started out burning only wood and it really took me some serious adjusting to my burning style and a lot of start coal fires and shovel them out for not staying lit.
Some swearing too!
I thought I was a professional wood burner, so how hard could it be to burn coal?
Well it was a big adjustment for me to burn coal from only wood. Wood gives you instant fire, hot now. Coal on the other hand gives you just as much heat, but over a slower build up time and a much longer burn cycle. Be patient and don't get all frustrated.
It is a learning curve. Once you got it down, you'll be even a better wood burner. :
Glad to help. Keep us posted. DOUG
