Pressure Switch Tubing
Figure 15 displays the proper routing of pressure switch
tubing for *TC furnaces. All upfl ow / horizontal furnaces
have two pairs of switches. One set is connected to the
static tap on the inducer assembly and the other to the
collector box. Downfl ow (*TL) furnaces require only one
pair of switches to be connected to the inducer’s static
tap. See Figure 16.
