Installation must meet the requirements of governing codes or, in the

absence of governing codes, in accordance with the National Electrical

Code, ANSI/NFPA 70, or Canadian Electrical Code, CSA C22.1, or IEE

wiring regulations (BS7671). The electrical subpanel must have an

uninterrupted or unbroken ground to minimize personal injury if an

electrical fault should occur. This ground can consist of electrical wire

or conduit approved for electrical ground when installed in accordance

with existing electrical codes. Do not use gas piping as an electrical

ground.

• GTS humidifiers must be supplied with 120-volt AC, 60 Hz

(North American models) or 230-volt AC, 50 Hz (European

models) separately fused electrical service. The GTS humidifier is

equipped with a transformer to step down the voltage to 24 VAC

control voltage.

• When installed, the GTS humidifier must be electrically

grounded in accordance with governing codes or, in the absence

of governing codes, in accordance with the National Electrical

Code, ANSI/NFPA 70; or Canadian Electrical Code, CSA C22.1;

or IEE wiring regulations (BS7671).

In North America, the electrical conductors shall be Type MTW

(105 °C) AWG #14 (2.5 mm

) wire for 120 V line voltage , with

BLACK WIRE for HOT, WHITE WIRE for NEUTRAL, GREEN

AND YELLOW WIRE for GROUND. Units with outdoor

enclosure must use AWG #12 (4 mm

) for 120 V line voltage. Use

#18 gauge (1 mm

) for control wiring.

In Europe, the electrical conductors shall be Type MTW (105 °C)

2.5 mm

wire for line voltage (230V), with BLACK WIRE for

LINE, BLUE WIRE for NEUTRAL, GREEN AND YELLOW

WIRE for GROUND, and 2.5 mm

wire for control wiring.

• All electrical components and wiring must be protected from

mechanical damage and water. The control system requires an

earth ground for proper operation.

• The GTS humidifier is adjusted for correct performance. Only a

qualified gas appliance technician may alter throttle setting.

• Check the electric current characteristics and capacity

requirements against the nameplate. All wiring must be in

accordance with all governing codes and with the GTS wiring

diagrams located inside the control cabinet. See table on Page 8

for information on the various models.

• Refer to the Vapor-logic4 Installation and Operation Manual for

additional information on the controller furnished with this GTS

humidifier.
