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.

• Dashed lines indicate provided by installer.

• Humidiﬁer ﬂue gases must be vented to the outside

atmosphere.

• The water supply inlet is more than 1" (25 mm) above

the skim/overﬂow port, eliminating the possibility of

backﬂow or siphoning from the tank. No additional

backﬂow prevention is required; however, governing

codes prevail.

• Damage caused by chloride corrosion is not covered by

your DRI-STEEM warranty.

• See the next page for recommended water supply

piping for DI/RO water models.
