Thanks for the replies.....I will give the one I have a try. It's a garage....so I think it will be fine. If the fumes are bad, I'll sell the thing and buy something else.
If that kero-heater is an older one....even before you look at it,,you best take in and get it tuned up or it will smoke you out and stink like He//..your room will look like the fog came in...
