Before attempting to relight the pilot, it's crucial to take safety precautions. If the pilot went out unintentionally, turn the gas control knob on the water heater to the 'OFF' position. Then, turn the handle on the main gas supply line valve so it is perpendicular to the pipe, shutting off the gas. Wait for 5 to 10 minutes to allow any excess gas to dissipate. If you still smell a strong gas odor after waiting, evacuate the house and call your gas company or the fire department immediately.

Goal: Prepare for a Safe Relighting

  • Always wait 5-10 minutes after shutting off the gas to allow any residual gas to clear out before attempting to relight the pilot.
  • A strong, persistent smell of gas indicates a potential leak. Do not proceed. Evacuate and call for emergency assistance.

FAQs

What are the crucial safety steps to take before and during relighting the pilot light?

Always ensure there's no smell of gas before you begin. If you smell gas, immediately turn off the main gas supply, ventilate the area thoroughly, and do not attempt to light anything; call a professional. Always work in a well-ventilated area.

My pilot light won't stay lit after I release the gas control knob. What should I do?

This often indicates a problem with the thermocouple, which is a safety device that senses the pilot flame. Try holding the gas control knob in for a full 60 seconds (or even 90 seconds) after lighting to ensure the thermocouple heats sufficiently. If it still won't stay lit, the thermocouple may be dirty or faulty and might need cleaning or replacement by a professional.

Do I need the exact "Scripto Aim-n-Flame Max Flex Utility Lighter" or will any long lighter work?

While the specific Scripto model is recommended for its flexibility and length, any long-nosed utility lighter designed for fireplaces or grills will work, as long as it allows you to safely reach the pilot light without getting too close to the flame. Avoid using short matches or standard lighters, as they pose a burn risk.

I'm having trouble locating the access panel or the pilot light itself. Where are they usually found?

Most gas water heaters have an access panel located at the bottom front of the unit, covering the burner and pilot assembly. For older models, you might need to remove an outer metal cover first. If you're still unsure, consult your water heater's owner's manual for exact diagrams and instructions specific to your model.
