Twist this to the "OFF" position. Once the gas is turned off, you need to find the main power switch to the furnace. The power switch might not be on the actual furnace. Often, it is in a small breaker box that is mounted to the wall. Either way, it should be clearly marked and easy to find.

Most modern furnaces have self-igniting switches, so you don't need a match or anything. Your best bet is to simply follow the instructions for your specific model.
