Before starting, always read your appliance's manual, since different models have specific instructions. Generally, you'll need to first locate the gas control knob, usually marked with settings like "Pilot," "On," and "Off." Turn the knob to "Off" and wait at least 5 minutes to let any residual gas dissipate. Then, switch to "Pilot" and simultaneously press and hold the knob while pressing the ignition button or using a long lighter at the pilot opening. Once you see the pilot flame, continue holding the knob for 30-60 seconds to ensure the thermocouple heats up and keeps the gas flow. Release the knob gently and turn it to "On." Finally, reattach any access panels and set your desired temperature.As a designer, I consider how efficient lighting and safe access to controls contribute to both functionality and the overall user experience. If you’re planning a remodel or installing a new system, optimizing the heater’s location in your utility space—factoring in clear sightlines to the controls and adequate workspace—can make regular maintenance much more user-friendly. Such thoughtful home utility layouts not only improve safety but also add value to your living environment.Tips 1:If your pilot doesn’t stay lit, check for drafts, dirty pilot orifice, or a faulty thermocouple.
