I recently purchased a small space heater that accepts those miniature propane tanks that are used with camping equipment etc.
Example:
I screwed the tank into the heater, but the question is, is it safe to just unscrew it before it's empty? I've always dealt with normal size tanks with shutoff valves, so I'm not quite sure.
Thanks
