New spectrum delivered today! A couple of questions for the group... One brick on the back sticks out farther than the other. On the parts diagram, there is no brick in this spot. Behind this brick is a vertical steel bar which is about flush with the other bricks. Is this brick in front of the bar needed? Without it, I could certainly fit in longer logs. Also, there is a wire thingy sticking out right above the brick - whats that for? Enclosed is a pic without the brick in place.
