Loud pilot light? (i.imgur.com)

New house, 1940s, natural gas fireplace insert. The pilot light makes a high pitch hiss.

Sometimes it doesn't, for moments, but mostly it does it all the time.

In this video I've turned the knob back past pilot and towards off, I can make it stop.

Is this dangerous?

I know nothing about the systems in question, but it seems the "hiss" is in time with the flame changing shape. So, perhaps a blower or valve turning on/off, open/closing.

Again, I know nothing, but if it's a sound from the equipment turning on/off, I don't think it would be potentially hazardous. Probably very annoying though.

    I was twisting the valve ever so slightly to demonstrate that the noise can come and go with the pilot still lit.

    But yes, the flame was changing shape slightly when it was doing it by itself earlier, so something is definitely happening.

    Others say dust up in the nozzle, which makes sense it sat unused for awhile
