I'm installing a gas shutoff behind the stove in the kitchen. In the basement beneath that room is a gas water heater and a gas furance. I will be shutting off the gas to the house, of course. Should I close the gas lines to those two appliances as well? Should I power both of them completely down? I appreciate your advice. TIA.

Hi Pgraves...

If you are planning to shut the gas main off then I would recommend that you go the gas water heater and turn the gas valve to the off position... not the gas shutoff... but the gas valve to the off position. I would also tell you to shut off the power supply to the gas furnace and to turn the gas valve to the off position.

Do your work at the stove... be sure to install an ANTI-TIP device if it is supplied with your stove. This device saves lives!

If you care to test the new shutoff/fittings for leaks. Let me know.

Then you would turn on the gas and purge air/gas through to the new shutoff. Once you connect the stove and confirm that gas flows to the stove then you can go to the gas valves at the other appliances and light the pilots as directed on each appliance... there should be an obvious sticker/plate showing how.

It may take a little while to relight pilots. You can speed the process by releasing air at the unions at each appliance.. but be careful and use common sense here... OK? :)

Turn power back on to the furnace, set the water heater thermostat to correct setting and you should be all set.

Be careful!

MARK

Gas seeks the lowest level. Any appliance capable of creating a flame, nned to be OFF and guaranteed to stay off.

Anything with a standing pilot needs to be off. Don't use the stove or oven.

Don't operate any switches, especially ones at a lower level.

Ventilate well.

Yes, turn off any gas appliance you have. Install the gas valve then when you turn the gas back on purge the airout of the lines at the furthest point. Make sure that it is well ventilated, and wait a while to give time for any gas to clear out of the area.

Thank you for your advice gentlemen.
