- All wiring must be done with a wiring material having a temperature rating of at least 105°C.
Important
- The use of this manual is specifically intended for a qualified installation and service agency. All installation and service of these kits must be performed by a qualified installation and service agency.
- These instructions must also be used in conjunction with the Installation and Service Manual that originally shipped with the appliance, in addition to any other accompanying component supplier literature.
Installation and Wiring
Installation of wiring must conform with local building codes, or in the absence of local codes of the National Electric Code ANSI/NFPA 70 – Latest Edition. 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.
