Whew..... I was considering a napoleon fireplace and worried what this post might say. As long as the actual stove unit is ok then I would look into retrofitting some type of universal fan into the housing and have the power sourch checked too. It may take some time to get it right, but it may be the best solution.
Look I am just making a comment about my experience. I just thought I would see if there were any other cases like mine. I did not mean to start a war. No, Napoleon will not honor any warranty because it has expired. Like I said also the parts are a royal pain in the ass to get because NO ONE in the US of A stocks them. They have to come from the not so great white north each time. Last winter It took an extra month to get a fan because Napoleon was out of them in Canada
