What is piezo ignition on water heaters?
What is piezo ignition on water heaters?
The Piezo ignition button is located either on the gas valve or nearby. Its purpose is to manually light the gas burner for the first time or after a prolonged shutdown for maintenance or other reason.
Where is the piezo igniter button on water heater?
On some water heater models, you press and hold down a separate red button to start the pilot burner gas flow. If your heater has a built-in piezo-electric spark pilot igniter, look for a red or black button labeled “Ignition” on the top or side of the gas valve. Push the button to ignite the pilot.
How do you light a piezo water heater?
Manually ignite this pilot gas using the piezo igniter button by depressing the igniter until you hear a loud click. Continue to hold the button for up to one minute after the pilot light is lit to let the flame heat the thermocouple and generate sufficient voltage to the gas valve.
How do you test a piezo igniter?
Connect the piezo igniter to the electrode (figure 3), holding the electrode about ¼” to ½” away from the shell of the heater with the insulated pliers depress the piezo igniter. If a spark is present every time the igniter is pressed, the piezo igniter is fine, if no spark is seen, replace the piezo igniter.
Do piezo crystals wear out?
Piezoelectric materials, whether natural or synthetic, are crystalline in nature. They should last forever, but being very brittle can be damaged if dropped or even if driven at too high power. Such crystals used in electronics should last at least until the contacts touching the crystal faces wear out.
What is automatic Piezo ignition?
Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. Piezo ignition systems can be operated by either a lever, push-button or built into the control knob. An electric spark is usually generated once per turn of the knob or press of the button.
How long does a piezo igniter last?
How long does it last? While matches and lighters must be replaced or refilled, matchfree ignition systems are built to last for life. While malfunctions do occur, the average piezo lighter lasts for a minimum of ten years, far longer than even a whole box of matches!
