Butterfly Assembly
1. Install the spring clips (12-0457) (2 pieces) as shown in Figure 3G onto the butterfly frame.
2. The V-shaped center bar of the butterfly frame weldment should be positioned vertically, with the
bottom lining up with the slots farthest out on the cone and the top lined up with the slots farthest in
on the cone. This will give the butterfly frame weldment a slight tilt back (~ 1"). This aids the closing
of the butterfly flaps.
3. Use 1/4" x 1-1/4" bolts and nuts to fasten the butterfly frame weldment to the panels. Tighten the
1/4" nuts. Attach the springs from the doors to the spring clip and push the flaps open and they should
close automatically from the spring tension, completely sealed by the magnets on the butterfly frame
weldment assembly. See Figure 3H for assembly inside of cone.
