GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
See Piping beginning on Page 28 for directions on
installing water, drain, flue gas condensate, and gas
on the GTS humidifier LX series. For Outdoor Enclosure
specific items, see below.
SUPPLY WATER AND DRAIN
• Using the pipe chase
Use insulation to completely fill the area around
the pipes in the chase to maintain proper enclosure
pressure and protect unit components from elevated
moisture levels within the building; insulation must
serve as an effective vapor barrier.
Use the provided pipe chase cover to seal off the pipe
chase. Cut necessary holes, and seal after installation.
• Using the knockouts on the front of the unit
Heat trace and insulate piping if freezing temperatures
is a concern.
• Insulate supply water piping
inside the unit to avoid
dripping from condensation.
• For
cold climates

FLUE GAS CONDENSATE
For cold climates, do not drain condensate on roof. This
will cause the condensate to freeze and back up. Follow
local code requirements.
STEAM
The humidifier has two available steam distribution
configurations. The standard configuration has a steam
outlet on the right side of the enclosure. The optional
internal steam distribution configuration routes steam
within the enclosure and down through the pipe chase into
a building.
