I need to replace the flexpipe between my steel pipe and the propane insert. The one installed is too short.
Alas, there wasn't a shut-off installed at the fireplace, so I needed to shut off the LP from the tank outside.
I figured before I unhook anything, I should try and burn out the LP in the line via the gas range.
Question 1: Is that a necessary step? Seems that's safer than letting what propane is in the piles leak out into the room as I decouple the connections.
Question 2: How long should it take to burn out what's left in the line? I've been running the burners for about 10 minutes now. The flame has gone down, but it's still going (there's maybe 40' of pipe between tank outside and range).
(PS, I will be installing a proper shut off valve as I replace the flex pipe to avoid this in the future.)
