1) Line Voltage (120 VAC) Field Connections – See Figure 10.2 for line voltage connections. Provide a dedicated circuit for the
boiler of 15A or greater. A service switch is recommended and is required by many local codes. Locate this switch in accor-
dance with local codes or, in the absence of any, in a location where it can be safely accessed in an emergency involving the
boiler. All 120VAC connections to the boiler itself are made on the terminal strip on the high voltage PCB located on the left
side if the wiring compartment. From top to bottom, the connections on the terminal strip are:
• 120VAC Hot
• 120VAC Neutral
• Ground
• System Pump Hot
• System Pump Neutral
• DHW Pump Hot
• DHW Pump Neutral
