Thanks for the advice, both posters.
I was wondering if it was possible, only because I don't want to throw
away a perfectly good furnace, and I know this thing is probably only
worth $100. I didn't want to use a space heater, because I will only
use it occasionally, but when I do, I'd like to be able to heat it
Tank price isn't a problem, I have a couple of portable tanks I can
use, and shouldn't have to refill all that often if I'm not using it
often (probably only about once a week, for 6-8 hours.)
I'll check with the manufacturer to see if I can get parts, in any
Thanks, I'll let you know how it works out.
