How to fix wiring replacement and grounding requirements: step by step
- Use copper conductors only.
- If any original wire supplied with the furnace must be replaced, use wiring rated for the temperature shown on the diagram note (the number is cut off in the text, so check the unit's own wiring label).
- Use the manufacturer's specified replacement parts when servicing.
- Permanently ground the unit in accordance with the National Electrical Code and local codes.
- Disconnect all power before servicing or installing the unit, since multiple power sources may be present.
Safety: Gas, electrical and refrigerant work must be done by a licensed technician. Turn off power and gas before servicing, never bypass a safety control, and always follow the manufacturer's manual for your exact model.
