  1. Hi I have a White mountain hearth model VFSR-18 NF burner. The pilot light comes on fine and stays lit. It will ignite on low and will stay on but as soon as I touch the knob to turn it to high it instantly goes out. Any assistance would be appreciated.

    • Hi Janet

      To fix your White Mountain gas fireplace pilot not lighting issue, clean the dirt & debris between the igniter & thermocouple. Also, blowing compressed air into the pilot area is a good idea to clean it. Then, wait for a few minutes & try to ignite the unit. Hopefully, the problem will be fixed.

      Well, if the pilot light ignites but won’t stay lit, you may need to replace the igniter.

      Best of luck!
