Installation & Operation Manual

￿WARNING

NOTICE

￿CAUTION

ELECTRICAL SHOCK HAZARD – For your safety, turn off electrical power supply before making any electrical connections to avoid possible electric shock hazard. Failure to do so can cause severe personal injury or death.

Wiring must be N.E.C. Class 1.

If original wiring as supplied with boiler must be replaced, use only type 105°C wire or equivalent.

Boiler must be electrically grounded as required by National Electrical Code ANSI/NFPA 70 – latest edition.

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

Installation must comply with:

1.National Electrical Code and any other national, state, provincial, or local codes, or regulations.

2.In Canada, CSA C22.1 Canadian Electrical Code Part 1, and any local codes.

Line voltage connections

1.Connect 120 VAC power wiring to the line voltage terminal strip in the junction box, as shown in FIG. 8-1.

2.Provide and install a fused disconnect or service switch (15 amp recommended) as required by the code (see FIG. 8-1).

3.When connecting a domestic hot water (DHW) pump, connect the wiring to the line voltage terminal strip as shown in FIG. 8-1.

4.To activate a system pump, wire as shown in FIG. 8-1. Dry contacts are sized for 1.5 hp/120V, 3 hp/240V or 30 amps.
