Notes:
1 Locate air gap only in spaces with adequate temperature and air movement to absorb flash steam; otherwise, condensation may form on nearby
surfaces. Refer to governing codes for drain pipe size and maximum discharge water temperature.
2 Pitch vapor hose, tubing or pipe toward dispersion tube:
– 2"/ft (15%) when using vapor hose
– ½"/ft (5%) when using 1½" tubing or pipe
3 Dashed lines indicate provided by installer
