Banish water heater woes: the step-by-step guide to lighting pilots

Water heaters are essential appliances in our homes, providing us with warm water for showers, baths, and various household tasks. When the pilot light goes out, it can be frustrating and inconvenient. However, lighting a gas water heater pilot is not as daunting as it may seem. Follow this comprehensive guide to restore your hot water supply in no time.

Safety First: Essential Precautions

Before embarking on this task, ensure the following safety precautions are taken:

• Turn off the gas supply to the water heater.
• Open windows or doors to ventilate the area.
• Have a fire extinguisher nearby in case of emergencies.

Step-by-Step Guide to Lighting the Pilot

1. Locate the Pilot Light Assembly

Identify the pilot light assembly on the front or side of the water heater. It typically consists of a small metal tube with a small flame burning at the end.

2. Turn the Gas Valve to “Pilot”

Locate the gas control valve and turn it to the “Pilot” position. This allows gas to flow to the pilot light.

3. Press and Hold the Igniter Button

Press and hold the igniter button, which is usually located near the pilot light assembly. This ignites the gas and creates a spark to light the pilot light.

4. Release the Igniter Button

Once the pilot light is lit, release the igniter button. The flame should remain steady.

5. Adjust the Pilot Light Flame

If the pilot light flame is too small or too large, adjust the flame height using the adjustment screw located near the pilot light.

6. Relight the Pilot Light if Necessary

If the pilot light does not ignite after several attempts, repeat steps 3 to 5. If it still fails to light, there may be an issue with the igniter, thermocouple, or gas supply.

Troubleshooting Common Issues

Pilot Light Goes Out Frequently

• Check for drafts or wind near the water heater.
• Ensure the thermocouple is clean and not damaged.
• Inspect the gas line for leaks or obstructions.

Pilot Light Will Not Light

• Replace the igniter or thermocouple if they are faulty.
• Check the gas supply and ensure it is turned on.
• Clean the pilot light assembly and burner tube.

Maintenance Tips for a Stable Pilot Light

• Clean the pilot light assembly and burner tube regularly.
• Check the thermocouple and igniter for any damage or corrosion.
• Inspect the gas line for leaks or obstructions annually.

Call for Professional Assistance

If you encounter any difficulties or safety concerns while lighting the pilot light, do not hesitate to contact a qualified gas plumber or HVAC technician.
