How to Relight Your Pilot Light: A Step-by-Step Guide
If your gas boiler, furnace, or water heater has stopped functioning properly, the first step you should take is to relight the pilot light. The pilot light is the small flame that ignites the main burner to generate heat. Relighting it is usually a straightforward process, but it may take some trial and error, especially if you’ve never done it before. Here’s a step-by-step guide to help you get your appliance up and running again.
What Is the Pilot Light?
The pilot light is the small flame that lights the main burner in your boiler, furnace, or water heater. It’s an essential part of these devices, as it ignites the gas that generates the heat you need for various purposes, such as central heating, hot water, or space heating. Typically, the pilot light is located near the base of the appliance and is marked with a small diagram of a flame.
Equipment Needed
Before you begin, make sure you have the following equipment:
- A pilot light or lighter
- A pair of safety goggles
- Gloves
- A match, lighter, or torch lighter
Step-by-Step Instructions
Preparation
- Locate the pilot light and nearby shut-off valves. Look for the pilot light marking or a diagram showing where it’s located. Write down the location for later reference.
- If your appliance has multiple ignition points, identify which pilot light you need to relight.
Safety Reminders
- Keep a bucket of sand nearby in case of accidents involving sparks or flames.
- Keep children and pets away from the appliance when relighting the pilot.
- Make sure to ventilate the area or use a fan to ensure proper air circulation.
- Avoid smoking or wearing clothes with loose threads around flammable materials.
Lighting the Pilot
Method 1: Matches or Lighter
- Open the pilot gas valve by turning the control clockwise.
- Turn the gas valve fully in one direction (not too tight, just one position).
- Press down on the pilot light to release any gas buildups.
- Use matches or a lighter to gently touch the pilot light head.
- Adjust the flame so it’s in the correct position.
- Release the pilot button or light switch and quickly check the flame for normal operation.
Method 2: Torch Lighter
- Attach a pilot light or flame booster to the pilot light (if equipped).
- Follow the manufacturer’s instructions for attachment and ignition.
- Check that the pilot light is positioned correctly.
- Gradually turn the pilot control valve counterclockwise until the flame disappears and then release.
- Reopen the gas valve by turning it clockwise while keeping the pilot control in the middle position.
After Relighting the Pilot
- Inspect the appliance for normal function, checking for adequate warmth or water flow.
- Monitor the appliance and pilot light for leaks, unusual sounds, or foul odors.
- Record the date of repair for future reference.
- Keep the appliance records handy in case you need to schedule maintenance or need to share information with HVAC professionals.
Tips and Precautions
- Relighting the pilot light regularly can prevent longer, more costly issues, such as clogged tubes or rust buildup.
- Make sure you purchase a high-quality replacement gas valve and pilot assembly parts if you need to upgrade.
- Regular inspection and maintenance can extend appliance lifespan and reduce potential emergencies.
- When possible, contact a qualified heating technician for assistance or annual maintenance, especially for systems that pose a significant health or safety risk if poorly maintained.
By following this step-by-step guide and exercising caution, you can successfully relight your pilot light and get your essential appliances running smoothly. However, if you’re uncomfortable with this process or need additional assistance, don’t hesitate to consult a trained HVAC professional.
