Ok thanks. The cool down is more annoying I agree. It pings for hours. Sometimes 6 hours. My parents have a pacific energy different model and it doesn’t make any noises so it’s strange. Seems like it’s the stove top doing it now that I fixed the baffle issues.That does sound a lot louder than mine . I usually have the t.v on and don't really notice it too much on start up , more on cool down. Funny I never gave too much thought about it because were heating the stove up from 60 f to 700 f so there is going to be a fair amount of expansion. I'm on my 3rd year of heating almost every evening from oct to april and am impressed with this stove. I will video mine sometime this week and put it up so you can compare.
