Steam hose, tubing, or pipe (tubing or pipe must be
grounded). Insulate tubing and hard pipe to reduce
steam loss. Do not insulate steam hose. See Table
24-1 for maximum piping lengths.
Pitch*
Open drain required. 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.
* Pitch steam hose, tubing, or pipe toward dispersion tube:
– 2"/ft (15%) when using steam hose
– ½"/ft (5%) when using 1½" tubing or pipe
Dashed lines indicate provided by installer.
