How to Light Gas Logs With a Piezo Igniter

A piezo igniter is an electronic ignition device that produces a spark when pressing the plunger switch. Because it delivers a single spark rather than a continuous flame, the piezo igniter offers a safer way to light gas appliances, such as fireplace gas logs. Many gas log fireplace inserts are equipped with an igniter for lighting the fire. The push-button operation enables you to start the logs without risking a flare-up that could occur with a lighted match or hand-held butane lighter.

Skill level:
Moderately Easy


  1. 1

    Open the glass doors or screen covering the fireplace.

  2. 2

    Push in and turn the burner control knob clockwise to the "Light" or "Ignite" position. The precise wording will vary, depending on your model.

  3. 3

    Immediately press the red button on the piezo igniter fully until you hear a click. Closing the plunger below the button produces a spark at the burner to light the gas logs.

  4. 4

    Press the igniter button not more than twice if the burner fails to light.

  5. 5

    Twist the burner control knob to the locked "Off" position. Wait 10 minutes for the gas to dissipate before trying again to light the logs.

Tips and warnings

  • Contact a qualified repair technician to replace the piezo igniter if it fails to light the fire after numerous attempts. The igniter can go bad and wear out over time, requiring replacement.
