Finally after a year of having problems with my M55, my dealer installed the new High Output Combustion fan today. All went well and certainly it blows more air into the room, however that is all it seems to be doing. I am noticing the I am not getting the same BTU output that I was getting with the old, original fan. I put a magnahelic gauge on it today and adjusted it down to .015 t .017 and all seems well but I can not seem to get the same level of heat that I was getting with the older fan. I am getting luke warm air and a very fast flame. I am running Okanakas and running the heat level at 3, air at 2 and feed at 2. Anyone have any ideas or advice that I can try to create more heat output from this stove. BTW - this stove is one year old and the control touch panel needed to be replaced today, the porcelain is burning off the door and the high low switch does not seem to be working and am waiting for a new switch - Go figure for $4500!!
