Takagi serial numbers encode the manufacture date in the first characters.
Where to find the serial
- Data plate on the side of the unit
- Installation paperwork
- Original packaging sticker for new installs
Decoding format
Takagi serials are typically 10-12 characters. Format:
- First 2-3 characters = year + month (e.g., 2207 = July)
- Remaining digits = factory sequence
