I purchased my Firelight(non cat) about a year and a half ago. So last year was my first full season burning with it. Loved the stove last season, no problems at all, never been overfired etc. So I went to clean it out this morning, to do so I took off the top plate and I found a decent sized crack on the flange underneath the plate. Is this a big deal? Should I call my dealer and see what they say?
