Be sure that you extend the bare copper wire down all branches of the system. Do not forget to connect the wires to each other with wire nuts when two branches meet at a “Y” or “T” connec- tion.
Ensure that the entire system is grounded. If using plastic blast gates to direct air flow, the ground- ing wire must be jumped (Figure 44) around the blast gate without interruption to the grounding system.
