How to Light Gas Water Heater Pilot: A Step-by-Step Guide

A gas water heater is an essential appliance in every home, providing hot water for daily use. However, when the pilot light goes out, it can be frustrating and challenging to relight it. Don’t worry! This article will provide you with a step-by-step guide on how to light a gas water heater pilot.

Before You Begin

Before attempting to relight the pilot light, make sure you:

• Turn off the main gas supply: Switch the gas valve to the "off" position to ensure your safety while working with gas appliances.
• Ensure the water heater is turned off: Check that the water heater’s thermostats are in the "off" position or have been disconnected to prevent accidental ignition.
• Check the pilot light mechanism: Verify that the pilot light mechanism is free from debris and obstructions, which can prevent proper lighting.

Step-by-Step Instructions

Follow these steps to relight your gas water heater pilot:

Step 1: Prepare the Gas Water Heater

1. Identify the pilot light assembly: Locate the pilot light assembly, usually situated near the bottom of the water heater.
2. Remove any protective caps: Take off any caps or covers that may be blocking access to the pilot light.
3. Clear any debris: Use a soft brush or cloth to remove any debris or soot that may have accumulated around the pilot light opening.

1. Press the pilot light button: Hold the pilot light button down for 3-5 seconds to release the gas pressure and open the pilot light port.
2. Light the pilot light: Hold a lit match or lighter flame to the pilot light orifice (usually located about 1 inch away). Keep the flame steady and consistent until the pilot light ignites.
3. Hold for 30 seconds: Continue holding the flame until you hear a gentle whooshing sound, indicating the gas is flowing properly.
4. Release the pilot light button: Once the pilot light is ignited, release the button, and the gas supply will shut off.

Step 3: Adjust the Pilot Light**

1. **Check the pilot light flame**: Adjust the pilot light flame height to the recommended **blue-tipped flame**, as specified in your water heater’s manual.
2. **Verify the flame stability**: Ensure the pilot light flame is stable and **not flickering or leaning**.

Step 4: Reset the Thermostat and Restart the Water Heater

1. **Reset the thermostat**: Switch the thermostat to the “on” position to re-establish the heating cycle.
2. **Restart the water heater**: Allow the water heater to re-start and begin heating the water.

**Tips and Considerations**

• **Pilot light troubleshooting**: If the pilot light still fails to ignite, **check for blockages or gas leaks** in the system.
• **Proper maintenance**: Regularly check and clean the pilot light mechanism to prevent malfunctions.
• **Annual professional inspection**: Schedule annual professional inspections to ensure your water heater is functioning safely and efficiently.
