If you have an older gas furnace, your heating unit relies on a little blue flame known as a pilot light to ensure ignition of the burners. Water heaters, gas fireplaces and old gas stoves also often have similar pilot lights. … Since the pilot light needs to remain active, your furnace is always consuming some gas.
Once the gas has had time to dissipate, turn the knob to “Pilot.” Then, hold down the “Reset” button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button.
Thereof, Where is the pilot light on furnace?

Do I need to turn gas off if pilot light goes out?
If the pilot light goes out on a storage or instantaneous hot water heater, space heater or a ducted heater, you will not have a gas leak.
