ELECTRICAL WIRING

Electrical Power Connections

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

ATTENTION: Au moment de l’entretien des commandes, étiquetez tous les fils avant de les débrancher. Des erreurs de câblage peuvent entraîner un fonctionnement in-adéquat et dangereux. S’assurer que l’appareil fonc-tionne adéquatement une fois l’entretirn terminé.

The electrical connections to this boiler must be made in accordance with all applicable local codes and the latest edition of the National Electrical Code, ANSI/NFPA-70. Installation should also conform with CSA C22.1 Canadian Electrical Code Part I if installed in Canada. Install a separate 120 volt 15 amp circuit for the boiler. A shut-off switch should be located at the boiler. The boilermust be grounded in accordance with the authority having jurisdiction, or if none, the latest edition of the National Electrical Code, ANSI/NFPA-70.

Line voltage field wiring of controls and other devices must conform to the temperature limitation of type T wire at 95°F, 35°C, above room temperature. Use copper conductors with a minimum size of #14 awg. Low voltage wiring must not be less than #18 awg with a neoprene, thermoplastic or other equivalent insulation having a minimum insulation thickness of 0.012 in, 0.3 mm.

THERMOSTAT INSTALLATION

Always follow the instructions included with the thermostat to be used to control the boiler. Proper location of the thermostat will ensure efficient trouble-free operation of the boiler. Mount the thermostat to an inside wall at a height approximately five feet above the floor. Avoid placing the thermostat in areas that will not provide an accurate measurement of the room temperature. Locating the thermostat behind a door, in an alcove, close to a source of thermal radiation or in a drafty area will cause poor or sporadic heating.

CO DETECTORS

WARNING: Installers must follow local regulations with respect to the installation of CO detectors and follow the manufacturer’s stated maintenance schedule for this boiler!

ATTENTION: Observer les règlements règional à l'egard des détecteurs de monoxyde de carbone et observer entretien de manufacturier pour cette chaudière!
