The appliance, when installed, must be electrically grounded in accordance with the requirements of the authority having jurisdiction or in the absence of such requirements, with the latest edition of the National Electrical Code ANSI/NFPA No.
70.When the unit is installed in Canada, it must conform to the CAE C22.1, Canadian Electrical Code, Part I and/or local Electrical Codes. Multiple units connected in a Cascade must be grounded to the same ground connection.
1.All wiring between the appliance and field installed devices shall be made with type T wire [63°F (35°C) rise].
2.All line voltage wire exterior to the appliance must be enclosed in approved conduit or approved metal clad cable.
3.The circulating pump must run continuously when the appliance is being fired.
4.To avoid serious damage, DO NOT energize the appliance until the system is full of water. Ensure that all air is removed from the heat exchanger and piping before beginning initial operation. Serious damage may result if the appliance is operated without proper flow.
