OK, I just pulled the oven away from the wall and there is no valve to
shut off between the floor and the flexible metal pipe. There's just
the metal pipe coming up through the floor, the flexible tube and the
oven. Any ideas on how to handle this? I wonder if maybe there's a
valve below the floor, in the crawlspace. FWIW - the house was built
in 1950, and I suspect this is the original location for the oven.

Since gas is tricky and potentially bad for the house and you, I advise to
get a plumber/gasfitter to work on it, unless you really know what you are
doing. Number one: You want to get the gas shut off somewhere between the
mains coming in and the location of your oven. Without that (in real good
working order - you won't want that main shutoff to fail!), you are close
to being in grave danger, even if you knew wwaht you are doing.

Grave danger? Nuts.

0. check for and eliminate sources of ignition, such as a candle-powered
miner's helmet on your head, or a cigarette in your mouth.

1. gather together one slicer valve, preconfigured in the closed
position, one roll of teflon tape, one finger, and an appropriate
wrench.

2. remove flexible pipe from supply pipe.

3. insert finger (note that subsequent steps will be slightly easier if
the finger used is not your own.)

4. clean threads

5. wrap threads with tape

6. remove finger

7. install valve
