How to Light a Gas Water Heater Pilot: A Step-by-Step Guide
Lighting the pilot of a gas water heater is a relatively straightforward process, but it requires attention to detail and safety precautions to avoid accidents or damage to the unit. In this article, we will provide a comprehensive step-by-step guide on how to light a gas water heater pilot, so you can get back to enjoying warm water with peace of mind.
Step 1: Safety First
Before attempting to light the pilot, ensure the following:
- Turn off the main gas supply switch or valve to the gas water heater.
- Do not attempt to light the pilot with the burners or thermostat on.
- Make sure the room where you will be lighting the pilot is well-ventilated and free from explosive gases.
- Have the user manual or a maintenance guide nearby for reference, if needed.
What You’ll Need:
- A gas water heater with a pilot ignition
- A screwdriver
- A wrench ( adjustable or open-end)
- A non-flammable holder or stand for the pot or lighter
- The pilot assembly (including the pilot light, gas shutoff valve, and T-stat valve)
The Lighting Process:
Follow these steps closely to ensure a safe and successful pilot lighting.

Step 2: Remove the access panel
- Access Panel: Locate the access panel on the front or side of the water heater. This panel will require a screwdriver to remove. Some heaters may have a lock clip or screws, while others may simply lift off with a slight pull. The panel may also be accessed from the top by twisting and pulling the plastic frame.
Step 3: Locate the Pilot Assembly
- Identify the Pilot: On most water heaters, you’ll find the pilot light assembly attached to the thermocouple or situated directly above the burner.
- Remove any caps: Remove any caps, wires, or clips holding the pilot light assembly in place.
Step 4: Turn off the Gas Valve
- Shut Off Gas Flow: Use a wrench or adjustable wrench to turn the gas valve counterclockwise. Turn it as far as possible to shut off gas supply to the pilot. Remember to always turn the gas valve counterclockwise to ensure it shuts off completely.
Step 5: De-burr and Clean the Tip
- Inspect Tip: Use a flashlight, if needed, to check the pilot tip for buildup or debris. Debur the tip using a thin, pointed tool, such as a safety match or a small nail cleaner.
- Soak in Water (if necessary): If rust or debris is significant, soak the tip in warm water and baking soda for about an hour to help loosen buildup before attempting to light.
Step 6: Light the Pilot
- Hold the lighter or matches near the de-burred pilot tip with the burner cap or plastic cover still removed. Do not let the flame fall onto the pilot tube assembly.
- Suffocate the flame: Release the pilot gas slightly (about ½ turn clockwise). Hold the flame for the recommended 1-5 seconds (dependent on the model) while making sure not to cover any openings or holes.
Step 7: Observe the Pilot Light and Adjust as Needed
- Wait for Pilot Spark: Once the flame begins to appear, carefully let go of the matches/lighter and remove the burner cap/plastic cover. If the flame is flickering or too high, shut off the gas supply momentarily and readjust the pilots’ alignment or position **(turn the adjustment mechanism clockwise to lower or counter-clockwise to raise).
Step 8: Restore Gas Flow (and verify the Pilot Function)
- Flip the gas valve open by turning it clockwise only half a turn (about 1.25 turns total).
- Listen for gas supply: Wait for about 30 seconds and test the pilot light with an insulated handheld pyrometer or a simple finger test. You might feel the gentle stream of gas when the valve reaches the "on" position.
Troubleshooting Common Issues
In case of difficulties:
Failed Pilot Attempts: If the pilot does not light:
- Repeal and re-do these steps carefully.
Re-check gas supply connections to ensure proper flow.
- Sputtering flame: Check for airflow within the room and make necessary adjustments to ensure adequate supply.
Maintain Your Pilot Light for Success
Regular Pilot Maintenances:
Schedule an annual professional cleaning and inspection of the water heater to avoid wear and tear, especially as the appliance ages. Be sure to follow these guides and keep your gas water heater pilot light functional.
