Notes:
• GTS standard water models can be
converted in the field for use with
deionized/reverse osmosis (DI/RO) water.
GTS-DI models can be converted in the
field for use with potable or softened
water.
• Damage caused by chloride corrosion is
not covered by your DRI-STEEM
warranty.

GTS standard water models
GTS standard water gas-fired humidifiers burn either natural
or propane gas to heat potable or softened fill water into steam
for humidification. The unit has from one to four burners that
fire into a heat exchanger submerged in a tank of water. When
there is a call for humidity, the burners fire and generate steam
until the call for humidity ends. A probe monitors water level,
requiring water conductivity to be at least 100 µS/cm to operate
properly. Therefore, GTS standard water models do not operate
with demineralized water (deionized or reverse osmosis treated
water). For demineralized water operation, use the GTS-DI model
(described on next page).
