Being licensed, In all honesty guys, unless you are licensed to be working on a gas appliance, i would not recomend it. It can lean toward unsafe operating conditions and potential further expenses. Some gas fireplaces come with a ppilot assembly that you need to replace the whole thing as opposed to replacing the pilot tube, thermocouple or thermopile. The potential for more damage while replacing parts is great too, if you don't know what you are doing. Please call a licensed contractor or maybe a local guy can check it out for you. I'm not trying to drum up busines lol just trying to keep people safe.
