Ok, here’s the scenario…It’s cold, really cold. When cold weather like this hits your area, you go on vacation to significantly warmer climates. While you’re away, lying on tropical beaches soaking up the sun’s rays, the power goes out for about 6 hours in your neighborhood because of fallen power lines. You can’t remember the brand name of your gas furnace, but you know it has a pilot light. Once you find out about the power outage you begin to get nervous. Does that mean your pilot light will go out and your furnace will not be running? Will your pipes freeze? Should you get on the next plane back home?
The most general and safe answer to these questions would be to call a professional technician to have your system checked out, just in case. There is no way to guarantee that, in this scenario, your pilot will remain lit during a power outage. It is also a much safer choice to have a technician service the unit considering the potential for carbon monoxide or gas leaking into the residence.
