With my gas furnace, the only way to extinguish the pilot light is by shutting off the gas at the entry point of the house - the master shut off. And yes, if you do manage to blow out the pilot flame without shutting off the gas first, there will be a continual leak into your home - very dangerous!
there is no danger of gas leak. the thermacouple cools when there is no gas burning, shutting off the gas flow. notice how you have to hold the pilot light in for 30 seconds. that is just enough time to heat the thermacouple allowing the gas to continue to flow. add a comment
