bought a Duluth Forge insert and the recommended blower (FIB-100). am trying to figure out how the blower goes into the insert itself. the opening on the side is too small and if i try to insert it through the front one of the gas feed lines is in the way. I do see where i can remove some screws and the whole assembly might move upwards allowing me enough room to go in and rotate the blower 90 degrees into it correct position but am afraid of damaging anything that is tied to the back where the gas line connects. any ideas?
