For those of you in Southern NH, I called Abundant Life in Chichester (just outside Concord) to see if they had an "End of the Season Dealer Cleaning Service" They do. $129 for the works (chimney pipe for insert included). This is our first season so I wanted to see just how to remove the insert and see just what the procedure is for cleaning the various fans etc, Just need to call the service department whenever we're reaqdy to schedule the cleaning. Just an FYI....
