Safeguards
The GTS humidifi er has a number of safeguards to ensure proper operation:
• When there is a call for humidity, all of the combustion blowers must start. Each combustion
blower sends a signal to the microprocessor relaying its speed. If the speed is outside an
acceptable range, the GTS will not operate.
• The negative-pressure gas valves used on the GTS humidifi er are designed to keep a constant
ratio of air and gas throughout the operating range of the blower. If the blower fails to run, the
GTS humidifi er will shut down due to a blower fault.
• If the fl ue becomes blocked, the blocked fl ue sensor will shut down the humidifi er.
• During operation, the water level in the tank is monitored by a probe system for
tap/softened water humidifi ers and by a low water fl oat switch for humidifi ers with the RO/DI
water option (see Figure 3-1).
These water level monitors tie into the Vapor-logic controller. If the water level drops below a
safe point, the controller turns the burners off and tries to fi ll the tank. If unable to fi ll the tank
within a defi ned time period, an “Excessive refi ll time” alarm appears in the Vapor-logic Alarm
Log. The burners remain off until this alarm is cleared.
• In tap/softened water applications, the water level in the tank is also monitored by a redundant
low-water system that operates independently of the Vapor-logic controller. This system is tied
directly into the power source for the gas valves. If this system detects a low water condition,
the humidifi er shuts down until water is present. A “GTS low water alarm” will be active while
the condition exists.
• There is a temperature sensor near the top of the heat exchanger. If the water level drops too
low and both the main and redundant low water sensors fail to detect it, the temperature sensor
shuts down the humidifi er to prevent an unsafe condition.
• There is a limit-control thermal trip next to the temperature sensor. This thermal trip operates
independently from the Vapor-logic controller. If the water level drops below the heat
exchanger, the thermal trip will directly shut down the gas valves. The thermal trip has a red
button that must be manually reset before the burners are able to fi re again.

Product overview
FIGURE 3-1: GTS HUMIDIFIER COMPONENTS AND WATER LEVEL CONTROL TYPES
DI/RO water optionTap/softened water
Humidifi ers using tap or softened water control water levels
electronically using a three-rod probe. A redundant probe is used
as a safety device.
Humidifi ers with the RO/DI water option control water level using a
fl oat valve. A low-water cutoff switch and a redundant low-water cutoff
switch are used as safety devices.
Fill valve closes when water level
rises to this probe.
Fill valve opens when water level
is below this probe.
Controller disables burner if water level

Finding a location
WARNING
Installation requirements:
Installation must conform to the requirements of local and national directives and regulations for the installation of
gas-fi red equipment.
The humidifi er must be installed by a qualifi ed technician and meet the requirements of all governing codes.
Failure to follow these instructions could cause severe bodily injury or death.
• Provide a level, solid foundation for the humidifi er.
• Locate the humidifi er as near as possible to a chimney or outside wall so that the fl ue pipe from the humidifi er is
short and direct.
• Install the humidifi er where its electrical components are protected from water during operation and service.
• Install the humidifi er in a location away (and protected) from drafts. If installed in a separate room, follow the
instructions concerning combustion and ventilation air.
• Install the humidifi er in an area where leakage from the tank or its connections will not result in damage to the
adjacent structure or to lower fl oors of the structure. When such locations cannot be avoided, install a suitable drain
pan (adequately drained) under the humidifi er. The pan must not restrict combustion airfl ow.
• If located in an insulated space, keep the humidifi er free and clear of insulating materials. Insulating material can be
combustible. Inspect the humidifi er area when the humidifi er is installed or when insulation is added.

Wiring and supply water piping requirements
WIRING
WARNING
Installation must meet the requirements of governing codes or, in the absence of governing codes, in accordance
with IEE wiring regulations (BS7671). Failure to follow these instructions could cause a fire, resulting in severe
bodily injury, death, or significant property damage.
Follow the instructions below for GTS humidifi er wiring:
• Use only copper wire.
• GTS humidifi ers must be supplied with 230 Vac, 50 Hz, separately fused electrical service.
• The electrical subpanel must have an uninterrupted earth ground to minimize personal injury if an electrical fault
should occur. Install in accordance with existing electrical codes.
• Do not use gas piping as an electrical earth ground.
• All electrical components and wiring must be protected from mechanical damage and water.
• Check the electric current characteristics and capacity requirements against the nameplate. All wiring must be in
accordance with the governing codes listed above and with the GTS wiring diagrams.
SUPPLY WATER PIPING REQUIREMENTS FOR ALL WATER TYPES
Follow the GTS humidifi er supply water piping instructions below for all water types. Install supply water piping in
accordance with locally applicable installation regulations.
• Provide a shutoff valve and union in the supply water line to isolate the humidifi er from the water system while
servicing.
• To minimize electrolytic corrosion, install insulating unions to make connections between copper and other dissimilar
metal fi ttings, such as galvanized steel.
• Humidifi er tank must be full of water — and supply water free to fl ow into the tank — before the ignition sequence
of a newly installed humidifi er is initiated.
• If planning to use heated supply water, disconnect the supply water line from the water tempering device fi ll
manifold/tee. Install a pipe plug in the manifold/tee, and reconnect the water tempering device line to a cold water
supply.
• The supply water pressure range must be 172 kPa minimum with fi ll valve open to 552 kPa maximum with fi ll valve
closed. When using nonmetallic tubing for supply water, it must be rated for 100 °C minimum continuous operating
temperature. DriSteem recommends installing a 1 m piece of noninsulated stainless steel pipe directly off the
humidifi er prior to connecting to the nonmetallic tubing.
• Before connecting piping to the GTS humidifi er, thoroughly fl ush the supply water piping to prevent pipe residue
and stagnant water from getting into the humidifi er tank.
General supply water piping information:
• The end-of-season feature shuts off the supply water and drains the tank when there is no demand for humidity for
72 hours. This is a default setting and is user-adjustable.
• The humidifi er has a 25-mm internal air gap to prevent back siphoning into a potable water system. Some
governing codes may require additional protection, such as a vacuum breaker or backfl ow preventer.
• The supply water assembly has a DN10 pipe thread connection.
