I have an old model that didn’t come with a roll over switch. In installing one, do I take one wire from the gas valve 24 volt tabs and wire it thru the switch and back ?

Yeah you want it to break power to the gas valve. How old is the boiler? Most boilers do not have a resettable rollout switch, they usually have a fusible link

Thank you ! The boiler is circa 1990. I purchased the after market reset able roll over switch to add on for safety.

This is a Rollout switch.
Check the diagram of a more recent revision of your model boiler and install it in the same location. You will need wire rated for high temperature.
And this is a Spill switch.
If your boiler doesn't have one, do it as well. For that you can use typical 18/2 low volt wire.
