Testing the New Thermopile

After installing the new thermopile, I wanted to ensure everything was working correctly. I turned on the gas supply and ignited the fireplace to observe the flame. A steady and bright flame indicated that the new thermopile was functioning as expected. I also listened for any unusual sounds, which could signal an issue.
