What is a piezo igniter button on water heater?
Your water heater won’t work properly if the igniter won’t spark. When the piezo igniter is pressed down and released, an electric spark is produced to light the primary gas burner in the water heater. The electrode should release a spark simply by pressing the piezo igniter.
Do gas water heaters have electronic ignition?
* Caution: Most modern water heaters no longer use standing pilots. They use electronic ignition to ignite the gas. Do not attempt to manually light an electronic ignition system.
How do you light a piezo water heater?
Turn the gas control knob to the pilot position (Robertshaw gas valve). Depress and hold down the pilot set button or gas control knob to let the gas flow to the pilot burner only. Manually ignite this pilot gas using the piezo igniter button by depressing the igniter until you hear a loud click.
How long does piezo ignition 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!
Can you light a gas water heater with a lighter?
Turn the water temperature dial to Low and the On/Off/Pilot dial to Pilot. Push the On/Off/Pilot dial downward with one hand while lighting the barbecue lighter with the other. Quickly hold the barbecue lighter over the end of the pipe by the burner. The flame should light instantly.
How does the ignition of a water heater work?
A millivolt ignition system is a method of igniting gas furnaces, gas logs, and gas-fired water heaters. They utilize either a thermocouple or thermopile. These devices, when heated, provide the millivolts to a pilot solenoid valve in a gas valve. Thus the pilot light burning to heat the thermocouple or thermopile.
Should my water heater be on or pilot?
The water heater pilot light needs to stay lit for a number of reasons. Not only does it ignite the gas inside your heater, but it also helps to maintain the internal temperature of your water heater, which cools over time. Igniting the pilot light is the first step you take to turning on the water heater.
How do I replace the thermocouple on my water heater?
How to Replace a Hot Water Heater Thermocouple Step 1: Familiarize Yourself with Your Water Heater Step 2: Access the Thermocouple Step 3: Release the Thermocouple Step 4: Install Replacement Thermocouple Step 5: Re-insert Burner Unit Step 6: Test Water Heater and Finish
Do all water heaters have a thermocouple?
Not all gas water heaters have a thermocouple. Some newer models have an advanced temperature control system. Essentially, it is a microprocessor that constantly monitors and controls burner operation and maintains consistent and accurate water temperature levels.
