3. Installation
14 PNEG-1425 50" Galvanized Butterfly Fan
Butterfly Assembly
1. Install the spring clip 16-0108 onto the butterfly frame bar using one (1) 1/4" x 20" x 1" bolt (S-6998)
and one (1) 1/4" x 20" whiz nut (S-7215) as shown in Figure 3G .
2. The 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.
