NOTES:
1
Listed Input and Output Ratings are at minimum vent lengths at an altitude of 0 - 2000 ft. Numbers will be lower with longer venting and/or altitudes
greater than 2000 ft.
2
Ratings based on standard test procedures prescribed by the US Department of Energy.
3
The TRX requires a special venting system. Use only the vent materials and methods detailed in these installation instructions.
