We had a new fireplace built with a direct vent gas log insert installed. It vents straight out the back of the house. The problem is that it is on the windy side of the house. Every time the wind blows the flames grow big and blue then go out. I had a guy come in to look at it and he said its probably not the wind but i disagree fully because i can watch the wind blow then it happens. Plus on a calm day it will burn all day long. Any suggestions on what to do? I have put to much money into this for it not to work.
