Notes

1

  Central Furnace heating designs are certified to ANSI Z21.47 / CSA 2.3.

2

  For U.S. applications, above input ratings (BTUH) are up to 2,000 feet, derate 4% per 1,000 feet for elevations above 2,000 feet above sea level.

  For Canadian applications, above input ratings (BTUH) are up to 4,500 feet, derate 4% per 1,000 feet for elevations above 4,500 feet above sea level.

3

  Based on U.S. government standard tests.

4

  The above wiring specifications are in accordance with National Electrical Code; however, installations must comply with local codes.

5

  Refer to the Vent Length Table in the Installer's Guide or the Allowable Vent Length label located on the furnace.

6

  All *UH1 and *DH1 furnace models have a vent outlet diameter that equals 2".
