Hi .. My first post here! I just installed the M55 insert into my fireplace. Love the look of it. I also got a Mag to adjust it. I cannot seem to find in any of my searches what settings the stove is to be on when performing the Mag readings and adjustments. I see that you are supposed to run it on heat level 5 for 1 hour prior .. but then what? ???Turn it down to 3 and take a reading to adjust the damper to 14 - 17???
