The LH one is about where you added the flange for connecting the scat. I like it- puts the heat down low where it warms your lower half, then when the heat rises (as it does) it warms your upper body. I took a photo yesterday but it was too big to load here- I guess it's gotta be smaller than 4 MB.....
