Location and clearance recommendations
FINDING A LOCATION
• Provide a level, solid foundation for the humidifier.
• The GTS humidifier LX series vent and air piping can be installed through
the roof or through a sidewall. Use only vent/air piping methods described
in the IOM. Locate the humidifier as near as possible to an outside wall
or accessible roof space so that the flue pipe from the humidifier is short,
direct, and limited to wind exposure.
• Locate the unit so it and its electrical components are protected from water
during humidifier operation and service.
• Install the humidifier in a location away (and protected) from drafts. Follow
the instructions concerning combustion and ventilation air.
• Locate the humidifier in an area where leakage from the tank or its
connections will not result in damage to the adjacent structure or to lower
floors of the structure. When such locations cannot be avoided, install a
suitable drain pan (adequately drained) under the humidifier. The pan must
not restrict combustion airflow.
• If located in an insulated space, keep the humidifier free and clear of
insulating materials. Insulating material can be combustible. Inspect the
humidifier area when the humidifier is installed or when insulation is added.
• See the combustion air and flue gas venting section in the Installation and
Operation Manual for pipe termination locations and instructions.
WARNING
Installation requirements
The humidifier must be installed by
a qualified technician and meet the
requirements of all governing codes.
Failure to follow these instructions could
cause severe bodily injury or death.

Outdoor enclosure: Location
• The following information is not intended to supersede any requirements of
federal, state, or governing codes having jurisdiction; prior to locating the
unit, authorities having jurisdiction should be consulted.
• The GTS must be level and located so there is enough clearance for
opening the access panels (see recommended clearances on Page 5).
• Do not locate unit in areas where the surrounding air has high levels of
particulates, such as some industrial parks or areas near highways. In
situations such as these, you will need to filter the air inlets.
• The unit should be located so prevailing winds do not blow into the air
intakes.
• When located on the roof, the air intakes must be a minimum of 14”
(360mm) off the roof to prevent intake of snow or splashed rain.
• Locate unit so air intakes are not too close to other exhaust fan outlets,
gasoline storage, or other contaminants that could potentially cause
dangerous situations. Using and storing gasoline or other flammable vapors
and liquids in open containers near this appliance is hazardous.
