air gap
Steam hose, tubing or pipe. Insulate
tubing and hard pipe to reduce steam
loss. Do not insulate steam hose. See
Table 16-1 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.
Installation
Dashed lines indicate provided by installer.
