After noticing the threads about the baffle for the heat exchanger tubes for the M55 I was curious why my cast insert did not have one. Finally had an unrelated reason to call my dealer and ask them where the heck it was and was informed that the insert does not have a baffle covering the exchanger tubes and the freestanding model does. So...I was curious if anyone with a M55 insert has the baffle or not. It was mentioned on the forum that possible issues without a baffle include burn through of the exchanger and increased hopper temps. The heat exchanger tubes are cast just like the rest of the unit so I don't see them burning through unless I was burning some of that real expensive exotic chit Jtakeman gets. Just curious to put my mind at ease. Hopefully there's a consensus or else I'm going to have to call a Canadian to find out for sure. The Canadians are already convinced we're a bunch of morons (in general) so I'd prefer to save the stupid question for later...lol. Thanks in advance guys.
