Water heater wiring

PLUS-Line indirect water heaters utilize a snap-set connector for easy wiring between water heater thermostat and boiler controls (also see Section B or D). See Figure 6, below.

Terminal 1 of the snap-set is the normally-open contact; terminal 2 is the normally-closed contact; terminal C is common.
