I was referring more to the idea that the regulator could be knocked off
or the fitting between it and the tank split. That POL device on my
Marshall 290 says .9 gpm. So I guess as long as the leak is greater than
what, 1000 unlit burners on full, the safety device will shut it off?
Don't know, but if that .9 means gallons per minute, it could make a
pretty large cloud fast. Is this correct?
