3rd year burning with my Hampton insert. Each year seems to get a little better as I've got some great wood now. I've had about 5 cord of oak and maple split and stacked in single rows for about 2.5 years now. All covered now. Anyway.... My question is, I am unable to install a block off plate due to the extremely tight clearance I have..... I have about 3" of space above the stove to the top of my masonry fireplace.... Can I pull my stove out.... Put a layer of Roxul on the back of the stove between the bricks and then on top of the stove and up around the liner heading up the chimney? I already have some stuffed up and around the liner I'm just curious on the laying it on top of the stove part. I'd like to keep as much heat in the stove as possible as I remember last year being able to feel very warm brick outside of the house during burning. Thanks!
