I turned the fireplace completely off using the instructions I found down beneath it. (At least now I'll know how to turn the pilot light off in the summer. ) Then relight the pilot and then turned the gas back on. I turned it on from the wall switch and it burned yellow for a while then flickered off then on then off for a little while. I turned it off and turned it back on after a while and it light but didn't stay on long. It behaves as if there is air in the gas line, interruptions, not like it's overheating or anything. Here is my wild guess as to what may be going on. Last summer we saw yellow jackets or hornets coming out of the outside vent for the fireplace. I can't see up inside there but we have a real problem with the nests here. Is it possible that they have built nests up in there enough to block the flow of air? I can still try getting through to the gas company but if it's something like that they probably won't deal with it. Does anyone have any idea if this is possibly my problem. I don't want to stand out in the freezing cold to try to open that vent if I'm completely wrong. Since it was able to relight that must eliminate some possibilities? Sunny
