That what my dealer told me! We went through 2 different Mt Vernons with multiple problems, error codes, etc. To make things right, the dealer gave us two 1200i's, painted them sienna bronze, place the cast surrounds on them, and provided free installation. So far, so good. I'll post pictures soon. He has been checking in with us to see how the new stoves are working, and he called today to say that Quadrafire is pulling the Mt Vernon AE for now until the technology is improved. Has anyone else heard this information?
