could cause personal injury, property damage, or death. To prevent
hazardous conditions, read all warnings; lock all power disconnect
switches in the OFF position before removing any access panels; and
consult a qualified installer, service agency, local gas supplier, or
your distributor or branch for information or assistance. The qualified
installer or agency must use only factory authorized and listed kits or

• Inspect humidifier and accessories upon arrival for damaged, missing,
or improper parts. If there is a problem, call DRI-STEEM.
• Application of this humidifier should have special attention given to
vent sizing and material, gas input rate, and unit sizing. Improper
installation or misapplication of the humidifier can cause excessive
servicing or permanent component failure.
• When working on equipment, observe precautions in literature, tags,
and labels attached to or shipped with the unit and observe other
safety precautions that may apply. Wear safety glasses and work
gloves. Have a fire extinguisher available during start-up, adjustment
procedures, and service calls.

Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and any gas
control that has been under water.

• Should overheating occur, or the gas supply fail to shut off, shut
off the manual gas valve to the appliance before shutting off the

DO NOT install a shut-off valve on the piping connecting the
evaporating chamber to the steam outlet.
