Turn the gas control knob back to the 'PILOT' position. Push and hold the control knob in. While holding it, press the piezo igniter button multiple times until you see the pilot flame ignite in the sight glass. Continue to hold the control knob in for approximately one minute to allow the thermocouple to heat up. After a minute, release the knob. The pilot flame should remain lit. Finally, rotate the control knob to your desired temperature setting to allow the main burner to operate.

Goal: Restore operation

  • If you smell gas after attempting to light the pilot, stop immediately and ventilate the area before trying again. If the smell persists, call a professional.

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.
