How to Light the Water Heater Pilot Easily: 1 Minute to Understand Lighting Your Water Heater Pilot

Lighting the pilot on your water heater doesn't have to be daunting, whether you own a gas or propane model. Here’s a straightforward guide to help you light your water heater pilot easily and safely:

1. Find the Access Panel: Start by locating the small access panel near the bottom of your water heater. This protects the burner and pilot assembly.
2. Turn Off the Gas: For safety, turn the gas control knob to the OFF position and wait at least 5 minutes for any residual gas to dissipate.
3. Set the Control to Pilot: Switch the knob to the PILOT setting. Hold it down; this sends gas to the pilot for ignition.
4. Ignite the Pilot: Use the built-in igniter button (if equipped) or a long barbecue lighter to ignite the pilot. Keep holding the knob for about 60 seconds to let the thermocouple warm up and keep the flame lit.
5. Release and Set to ON: Slowly release the knob, making sure the pilot stays lit. If it goes out, repeat the process. Once successful, set the knob to ON and replace the access panel.

Tip from a Designer’s Perspective: Consider how lighting affects the usability and safety of your utility room. Adding layered lighting—like a ceiling fixture paired with an under-cabinet task light—makes maintenance on appliances like your water heater much easier and safer. For clients designing or remodeling their utility space, I often recommend integrating these lighting solutions into their home designer plans.

Tips 1:

Always check your manufacturer’s instructions. Models can vary—some have sealed burners and electric igniters, while older units require manual lighting. Additionally, regularly inspect for exhaust obstructions and ensure there are no gas leaks before attempting to light the pilot.

FAQ

Q: Why won’t my water heater pilot stay lit?

A: The most common reasons are a faulty thermocouple, dirty pilot tube, or issues with the gas supply. Replacing or cleaning the thermocouple often solves the issue.

Q: How do I know if my pilot light is out?

A: If you have no hot water, inspect the small window or access door on your water heater—no visible flame means the pilot is out.

Q: Can I light my water heater pilot if I smell gas?

A: No. If you smell gas, do not attempt to light the pilot. Leave the area and immediately contact your gas provider or emergency services.

Q: How often should I check my water heater pilot?

A: Check annually during routine maintenance, or whenever you notice a drop in hot water availability.

Q: Is it safe to relight the pilot myself?

A: If you follow the manufacturer’s directions and basic safety precautions, it’s generally safe. However, if you ever feel unsure or encounter issues, consult a licensed plumber or technician.
