B.BURNER WIRING

1. See Section 5 for mounting burner.

2Install junction box, limit harness, and Heyco bushing, each located in the trim carton. See Figure 4.1. Mount junction box to the holes in the left side of jacket with (2) #10 x 1/2" sheet metal screws. Attach Heyco bushing to 7/8" knockout in front side of junction box. Connect limit harness to 7/8" knockout on top of junction box and insert limit harness Molex connector into Heyco bushing until it snaps firmly in place.

Improper installation of burner WARNING harness can allow burner to energize

with burner mounting plate open, creating a severe burn hazard to boiler maintenance personnel.
