We have a twelve year old fire pplace insert with a side vent out the wall. We have had problems for years and many, many attempted repairs. None of these has been successful.
Problem: Mostly during high winds but often without them, the fire place just goes out. Sometimes within seconds of starting and sometimes after an hur or so. Wind comes in through the control area underneath. Mostley it starts and after fluttering for a few minutes, just extinguishes along with the pilot. It is a Heatilator. Any ideas would be welcome.
