GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
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.
• Supply water inlet is more than 2" (51 mm) above skim/overflow port,
eliminating the possibility of backflow or siphoning from tank. No
additional backflow prevention is required; however, governing codes
prevail.
• For additional backflow prevention installation, install at a minimum of
40' (12 m) from the humidifier.
• Damage caused by chloride corrosion is not covered by your DriSteem
warranty.
