Gonna convert existing elec cooktop to gas cooktop; there's a pre-plumbed gas line to that area.
Gonna shut the gas to the house in order to install shutoff valve, pressure regulator and a flex line.
My Q is: after I shut off the main gas, how long do I need to wait until furnace and water heater pilot lights consume residual gas in the line?? Or, is there a better way to bleed off gas??
Do water heater & furnace need to be electrically disconnected when I shut gas off??
Is regular teflon tape good enough to use at the connections??
Thanks in advance.

Hello masterjoe and Welcome to my Gas Appliances topic.
Residual gas in the lines is a very tiny amount. The pilots on the two appliances will consume the gas in the line in least than 1 minute. By the time you get back into the house the pilots will be out.
Neither water heater or furnace will need the power turned of. They will have to have the pilots relited when the project is completed.
Pipe tape is fine for the pipe threads only. The shut off valve connects to the supply pipe. Tape can be used on those threads. But not on the flex line connection ends. Use oil. Any type is ok.
The regulator for the stove does not get connected to the supply pipe. It gets installed in the gas inlet supply manifold on the appliance. Read the installations instructions carefully.
The regulator has an arrow to indicate the gas flow direction. The arrow face in towards the appliance. Look for that arrow prior to installing it.
No pipe tape on the threads. Use oil. Any type or pipe thread compound if you have it. No tape is to be used on any pipe the regulator gets installed on.
Do not over tighten the regulator onto the manifold pipe not over tighten the adapter that threads in to the other end. The metal cracks easily. Snug but not overly tight.
Complete the connections, soap yest every connection. Leak soap available at all appliance parts stores & most hardware stores.
