Page 27

Typically, control wiring between the appliance and the indoor thermostat, and if used, electronic air cleaner or humidifier, will be required. Field wiring of control circuits should consist of copper conductors rated for at least 15 amp service with an insulation temperature rating conforming to Type T wire, 35°C temperature rise. Depending upon code requirements, rigid or flexible conduit is recommended, and may be required. Make connections between the thermostat, and electronic air cleaner or humidifier (if used), and the fan control module, inside the vestibule. Consult the wiring diagram for the appropriate connection points on the thermostat and the fan control module.

Table 10: Typical Electrical Requirements

Wire size selections in Table 10 are based upon Table 310-16 of the National Electrical Code for three copper conductors, with insulation rated for 75 degrees Celsius, contained in raceway at 30 degrees Celsius. For other wire insulation temperature ratings and ambient conditions, refer to the National Electrical Code for the minimum wire sizing requirements.

NOTICE: Before the unit is started, the installer and/or electrician must check the following items:

1.Check every electrical connection of “push-on” or “screw-on” type terminals to ensure that all wires and wire connectors are firmly secured. A loose terminal can cause poor flow of electrical power to motors. This may result in very high current draws by these components. If great enough, high current draw will cause blown fuses, burned wires and contactor points, and pre- mature motor failure. Each electrical connection has been factory checked, however, connections may loosen, due to vibration, while the appliance is in transit. Please be certain that all electrical connections remain tight.

2.Review wiring diagram for proper routing and connection of all field wiring.

3.All wiring sizes must comply with local codes or the National Electrical Code. To minimize voltage drop to the appliance, the next larger size wire should be used when long wiring runs, in excess of 100 ft., are employed. Refer to the wiring diagrams when wiring or servicing.

In the event a circuit breaker trips or a fuse blows as a result of the operation of this appliance, investigate the appliance electrical system to determine the cause. Correct any electrical faults and abnormal conditions before putting the unit back into operation. Do not put in a larger fuse and do not exceed maximum fuse size listed on the rating label in order to temporarily “fix” the problem. The rating label is located on the inside of the burner compartment cover.

Electronic Air Cleaner (EAC) and Humidifier Installation:

The fan timer on this unit has designated terminals to control the operation of an electronic air cleaner and/or humidifier. These terminals provide line voltage for the control of these accessories, refer to Figure 15 on the next page. Connection between EAC and N6 provides a switched 115 vac to power an electronic fan cleaner. The same-switched 115 vac is available between EAC and N7 and may be used
