I need to do a better job gathering my thoughts before I post. First I misread the model number in the original post, and then I forget to mention that I have a Hydrostat 3150 on my EFM.
Good thing others are watching.
The only issue I had with the 3150 was lack of clearance between the aquastat well and the newly installed extended coil mount. That issue is probably unique to my boiler because it was retrofitted with the new coil mount. I didn't know they offered a remote mounting kit at the time, so I mounted the control on the boiler jacket and had to run a ground wire to the theromwell to make the LWCO function work properly.
