Plumb spill funnel to floor drain.
Floor drain
Open drain required directly below humidifier drain to prevent
downstream drain line blockage from causing water to back up
into cylinder. Refer to governing codes for drain pipe size and
maximum discharge water temperature.
1” (25 mm) air gap required to isolate drain
water from cylinder water. Locate air gap
only in spaces with adequate temperature
and air movement to absorb flash steam, or
condensing on nearby surfaces could occur.
