I hope someone can Help me out. I cannot get the unit to produce a nice inner blue flame. I am getting all kinds of flair up, tried different propane bottles same result. Also when shutting down it takes about 7 minutes for the flame to go out! Is this normal. I have used regular plumbers torches to anneal for years and never had a problem. Any suggestions? Do I have a bad valve?
thx Ted
