[quote="alpineboard"]I have am in the same situation with a tarm 202 , I have just purchased a 202 with shaker grates, they operate by opening the bottom door and hooking onto a hole at the end of the bottom connector bar. This bar connects the lower part of all the grates, so shake away. Now I can see that I need a plate at the lower door opening, so I do not fry that windowed little door and then the outside door. It looks like there is a 1"x1"x9" bar that will be removed, put the plate in that will be cut to fit, and put that 1x1x9 back in place to hold the plate there. This is all a guess but it seems to be that simple. Now my big question is, does a back plate exist? The front plate that I just described does not make the firebox any shorter, but in the manual it say that when burning coal, the fire box depth goes from 14" to 12". There are lower tabs on the bottom that are 2" inward. There are also horizontal 1/2" bars welded on both sides just below the 3 tubes. I will have to post some pictures soon so You can see. The good news is this 202 came with the two tube baffle plates that fit nicely between the 2 spaces.
Does any one have pics or drawings of the front and rear plate. The older link to woodboiler.com does not work anymore. I can get out to Lyme sometime to see if they have those plates(to look at?) thank you all, Robert
