steam from nonmetallic supply

piping.

2" (50 mm)

12" (300 mm)

Notes:

• 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.

• Offset humidiﬁer from spill funnel or ﬂoor drain to prevent ﬂash steam from rising into the cabinet.

• Dashed lines indicate provided by installer.

• The water supply inlet is more than 1" (25 mm) above the overﬂow port, eliminating the possibility of backﬂow or siphoning from the tank. No additional

backﬂow prevention is required; however, governing codes prevail.

• Install a union in the water supply and drain lines as shown to allow tank removal.

• Damage caused by chloride corrosion is not covered by your DRI-STEEM warranty.

Open drain required.
