Why do most gas fireplaces have standing pilots?
Most gas fireplaces use a standing pilot ignition system, just like a gas water heater. This system operates with a pilot light so there is always a flame to ignite the gas. The pilot light also generates the power needed to operate the valve, so that if the pilot light gets blown out accidentally, the valve shuts off and the gas flow stops. The pilot light feature makes operation both easy and safe.
