Hi all. My dealer seems to have disappeared; no responses to phone nor email. I purchased a demo steel fs M55 under under warranty in 2013. It has the old convection fan. Prior to purchase, he contacted enviro and relayed to me that unless I had overtemp shut downs that I was to stay w/ the old fan. Been running 9 weeks, levels 1-3; 3 overtemp shut downs to date. If anyone can provide an email contact, that would be appreciated.
