Figure 9: Recommendations for Thimble and Wall Penetration

VI. Electrical

A.General. Install wiring and ground boiler in accordance with requirements of authority having jurisdiction, or in absence of such requirements the National Electrical Code, ANSI/NFPA 70, and/or the CSA C22.1 Electric Code.

B.Install thermostat. Locate on inside wall approximately 4 feet above floor. Do not install on outside wall, near fireplace, or where influenced by drafts or restricted air flow, hot or cold water pipes, lighting fixtures, television, or sunlight. Allow free air movement by avoiding placement of furniture near thermostat.

C.Wire thermostat. Provide Class II circuit between thermostat and boiler. Run wires through grommet in Jacket Left Side Panel. Set thermostat heat anticipator to 0.6 amps. See Figure 10.

D.Wire boiler. Boiler is rated for 120 VAC, 60 hertz, less than 12 amperes. Provide individual branch circuit with fused disconnect. Connect to black and white wires and green ground screw. See Figure 10.

E.Alliance water heater (if used). See Figure 10. Also refer to Alliance Installation, Operating and Service

Instructions.

1.Zoning with Circulators, Domestic Hot Water Priority. Provide DPDT relay (included with PAL). Connect coil to Alliance thermostat (prewired with PAL). Connect normally open contacts (red and white wires in PAL control harness) to transformer terminals 'R' and 'Y'. Disconnect yellow circulator wire. Connect normally closed contacts (violet wires in PAL boiler harness) to yellow relay wire and yellow circulator wire.

2.Zoning with Circulators, Nonpriority. Connect Alliance circulator zone control (or red and white wires in PAL control harness) to transformer terminals 'R' and 'Y'.

3.Zoning with Zone Valves. Connect Alliance thermostat to zone valve. Connect zone valve end switch to relay terminals 'R' and 'G'. See Paragraph F.

F.For installations using zone valves provide separate transformer for zone valve wiring. Consult zone valve manufacturer for assistance.
