Gas stove in fifth wheel

Yes, any gas line can be terminated...shut off.

I have a valve that runs to my gas stove that I can turn off.

ditto above

Perhaps the OP wants to disconnect the gas stove (like ... remove it???) and still have gas available to the water heater. Or perhaps he is replacing the gas stove for an all electric one????

If that is the case, you'll need to simply add a shut off valve or cap it to the end of pipe leading to the gas stove when you remove it???? replace it????

But "no" there is no separate shut off factory installed for each individual appliance that is dependent upon gas. The expectation is to turn the propane tanks off, then do the work on the appliance, then turn the propane tank back on.

Your water heater should run on propane regardless of any other appliances (stove, refrigerator) connected or running at the same time. If it does not operate correctly, it's possibly due to (1) it being in the "electric" mode, (2) no 12V power (some models) (3) some switch not in the right position, (4) pilot light not lit (some models).

If you are trying to remove the stove and still have the water heater operational, you will need to turn the propane off, disconnect and cap the gas line to the stove, and turn the propane back on.

If you are having problems with gas flow and hence the water heater won't work, chances are you opened the propane valve at the tank to fast. In which case you need to close the valve, bleed some propane off (like light a stove burner for second or two), and re-open the valve very slowly.

If none of these are your problem, you need to be more specific about what you're trying to do, what is -or- is not happening, if everything worked fine before, and/or if this is a first time problem.

No shutoff valves on individual service lines to the appliances

IF propane to stove is LEAKING you will need to disconnect the propane line and cap/plug using a 3/8" gas fitting

Good grief. This is a new member's first post. And a question they need an answer to. No wonder participation in this forum is falling off.

To the original poster (OP). No reason to shut off gas individually to the stove. Just do as DrewE said above.

:?

Turn off all the stove control knobs and you should be good to go. Typically in an RV there are no individual gas shutoffs for each appliance, just the usual control valves and the main shutoff at the tank. The stove is no different in that regard than the furnace or fridge (if it's not a residential fridge)...or, for that matter, the water heater.
