* Field pitch condensate drain line a minimum of 1/8" (3.2 mm) per foot (305 mm). All units contain a factory-installed condensate trap. Do not
trap external to the unit. Drain line may contain boiling water. Select appropriate drain system materials. The drain line must comply with all
local codes.
