I saw the message where the gas fireplace kept going out and the flue was stopped up.

I have a 98%effecient LP gas fireplace w/o flue. When the outside temperature falls below 30 it keeps going out. I can relight it and just before it goes out it sounds like air is coming through the line and the flame turns yellow and clicks off.

Someone suggested a "cold weather" regulator to give more gas. What do you think?

Thanks
