Electrical Wiring

The electrical power supply requirement for these boil- ers is 120 VAC, 60 Hz. Field wiring connections and electrical grounding must comply with the local codes, or in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70.

Provide a separate fused circuit from the main electri- cal panel to the boiler, and a disconnecting means within sight of the boiler.

Remove the control box cover and make the power supply connections in the field wiring compartment. (See general location of controls drawing on page 28). The pump is supplied and factory-wired to operate with the boiler. The "TH" wire leads are for the room thermostat or zone valve connections.

The room thermostat should be installed in accor- dance with the manufacturer's instructions. The thermostat heat anticipator should be set at 1.0 ampere (automatic ignition) and 0.60 ampere (stand- ing pilot) for single- zone installations. For multi-zone applications, the heat anticipator setting should be based on the ampere load in the thermostat circuit.

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105°C wire or its equivalent, except 150°C black wire must be replaced with 150°C wire or its equivalent. See Fig. 19 for 150°C wire indication.
