1.Install electric wiring in accordance with National Electrical Code or the Canadian Electrical Code and local regulations. See Figure 11 for the wiring diagram and the boiler's Installation manual.

2. The Alliance™ models contain an aquastat assembly and will require an installer supplied double pole, single throw (DPST) relay with a normally open (NO) contact, a normally closed (NC) contact, and a 120 volt coil for priority domestic water. A Honeywell R4222D1013 is an appropriate relay. Refer to Figure 11. For non- priority, a SPST relay with one NO contact is sufficient. For non-priority and space heating with zone circulators, treat the water heater as an additional zone.
