We have had ventless for years. Like you, we have a flu and on the recommendation of the plumber who hooked up the fireplace, we leave it open slightly. The advantage of more heat is nice at the cost of looking slightly less realistic than vented logs. I have never encountered any issues with moisture. YMMV.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
