I will be installing a Mod-Moe in my cabin. (Probably early 80’s model from what I’ve been told.) With seasonal use, 10 -15 weekends a year, how often will I need to sweep the pipes? I know a lot of that will depend on the wood, type/seasoned/etc... But taking worse case scenario using well seasoned and some not so well seasoned wood how often should I look to sweep? The last thing I need is to burn down the cabin out in the middle of nowhereville! The chimney is not hard to get to but the less I have to climb the happier I will be.
