We replaced an old VC Vigilant last year with a Leyden (2007 model). Burned mostly nights and weekends from Jan. through March. In general, it gets a good review, but there are some wrinkles…We had a problem with the bypass flopping open. First time, I was absolutely sure I had closed the bypass, but when I looked, it was open. The second time it happened, I was in the room and heard the clunk as the handle released, like an invisible hand from across the room. My husband made a few adjustments with instructions from the stove shop. That helped somewhat, but from that point on we were very careful not to load up the firebox or leave the stove unattended. Stove shop called yesterday and said they had a ratchet kit for the damper which they wanted to install. Good piece of mechanical engineering…works like a charm, no chance of a “flop open” again. Also, they replaced the clips holding the glass in the doors and broke one panel of glass in the process…just went “tink” and went to pieces on one turn of the screw. Seems there has been a rather high rate of breakage because of faulty clips and heat expansion and we probably had a hairline crack we didn’t see. For Leyden owners out there who haven’t had a problem, I’m glad you didn’t. Just passing this info along for those of you who might not be aware of potential problems and the fix for them.
