Installation and Wiring

Installation of wiring must conform with local building codes, or in the absence of local codes, the National Electric Code ANSI/NFPA 70 - Latest Edition. The unit must be electrically grounded in conformance to this code. In Canada, wiring must comply with CSA C22.1, Part 1, Electrical Code.

Wiring Diagram Selection

• For gas-fired unit heaters and duct furnaces (non-factory supplied blower) with model numbers shown above, refer to Figure 1.1 and Table 1.1 for correct unit to thermostat wiring.
• For all other system units (factory supplied blower), refer to the job-specific unit wiring diagram provided with the unit.
• For deviations to these wiring diagrams or the job-specific wiring diagrams, consult the factory.

Notes for Table 1.1:

• (1) Not all terminal connections are used. Table only shows terminals that are used for required heating operation.
• (2) The factory-installed R to Rc terminal wire jumper is to remain in place.
• (3) Verify that the buss bar on the G terminal is removed.
• (4) Verify that the buss bar between the T2 and F terminal is removed.
