I just bought my insert last feb and I had the same thing happen to me. My burn times wern't that great. I was getting 5 hours of burn time. One thing I noticed is that you have to have a really good bed of ash to get long burn times. They say that ash is a insulature and your coals wont burn out as fast.
So for my napoleon insert I have to have at least two inches or more of ash to get a good eight hour burn and harder woods like oak and hick
Also my box is only 2.7
I hope this will help as it did for this newbe.
