does anyone by chance know what the clearence to top trim with a mantle shield is on a JOtul 350 Winterport? The manual doesn't say, and Jotul has yet to call back my dealer/my dealer has yet to call ME back. So just wondering if anyone in here has run into this at all. Does anyone even own one of these or seen in person? Because of my particular install, this insert is leading the small pack... THANKS!
