INDOOR INSTALLATION The installation must conform with local building codes or, in the absence of local codes, with the ANSI Z223.1, National Fuel Gas Code, and/or CAN/CGA B149 Installation Codes.
· DO NOT mount humidifiers in an area where freezing may occur. The gas inlet pipe size to the appliance is: ½” NPT for GS 100 ¾” NPT for GS 200 1” NPT for GS 300 / 400 1 ¼” NPT for GS 500 / 600 · If humidifiers are mounted on a roof, a properly ventilated, temperature controlled, (above freezing), weatherproof enclosure must be used. Provide an adequate size gas supply line. · DO NOT mount humidifiers on vibrating surface. Consult factory.
recommended that the supply air line is insulated and an in line heat is added. Consult factory. upstream of the gas supply connection to the appliance. Attach the air supply line to the manifold using a hose clamp or hose coupling if required. See Figure #4. COMBUSTION AIR REQUIREMENTS Provide for adequate combustion and ventilation air in accordance with Sections 8.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, ANSI Z223.1, or Sections 7.2, 7.3, 7.
· In applying the codes, reference should be given to the venting manufactures instructions, the serving gas supplier regulations, and the specific instructions provided in this manual. Location of air intake and flue gas terminal must comply with all local and national regulations. EXHAUST VENTING The GSTC and GSP are classed category I and III fan assisted gas appliances. This allows two methods of venting.
Figure #7 Vertical Venting Application Using B or BH Venting UL Listed Cap Required Flashing B or BH type vent using double wall vent with double wall connectors is required. Reference local and/or national codes before installation of the vent. 4" minimum air space required Horizontal run 1/4"rise per ft Exhaust venting outlet Steam Outlet Condensate tee required Trap 2 FT Min 3” Min. Condensate tee and trap must be installed. Take the condensate to a floor drain or a condensate pump.
Figure # 9 Co-venting Application Using B Vent Only UL Listed Cap Required B type double wall vent with double wall connectors is required for category I, serving two or more gas appliances. Condensate tee and trap must be installed. Take the condensate to a floor drain or a condensate pump. Exhaust venting outlet Condensate Tee Steam Outlet Trap Category I gas appliance uses B type venting. Follow local and/or national codes for venting installation. Note: These are guidelines only.
· Vent connectors shall not be connected into any portion of a mechanical draft system operating under positive pressure. · Vent pipe must be secured with hangers or pipe straps · All horizontal runs must be adequately supported with hangers or straps to prevent sagging. · The GS series humidifiers have a fan-assisted combustion which operates with a non-positive vent static pressure when installed with the appropriate vent diameter. · Use only double wall (aluminum inner wall) B vent.
· This appliance should not be connected to a chimney flue servicing a separate appliance designed to burn solid fuel. Never connect this humidifier to a chimney servicing a fireplace. WARNING: Provide a screen or barrier to prevent personal injury in areas where inadvertent personnel contact with vent pipe can occur. · A minimum equivalent vent length of 7 feet must be connected to the humidifier. Vent lengths must not exceed 100’ (30 m). Each 90° elbow is equivalent to 10’ and each 45° elbow equals 5'.
Field wiring from humidistat to humidifier and between devices should be shielded 18 AWG or heavier and kept as short as possible. The vent terminal must be installed in the same atmospheric pressure zone as the combustion air inlet of the humidifier. If this is not possible (as in cases of positive or negative room pressures) the humidifier should be installed with the direct vent option. Controls are available from NORTEC as accessories and can be ordered with the humidifier.

· It is recommended to have a faucet installed close to the humidifier to allow quick filling of the system on initial start up. This can also be very useful for mandatory cleaning of the unit. CONTROL INSTALLATION · Mount any wall humidistat (control or high limit) over standard electrical box at height similar to typical thermostat. Any wall humidistat should be in location representative of overall space being humidified and not in path of blower pack or air supply grille.
· The drain line should not end in a sink used frequently by personnel, or where plumbing codes prohibit it. Route to a floor drain or equivalent for safety reasons. Internal drain water tempering will ensure a maximum of 140ºF (60ºC) exiting water temperature. Figure #12 Steam Line Connection Steam Line · Never install PVC piping as a drain line material. Always use material suitable for with-standing 140ºF (60ºC). Snap on Insulation · Keep drain lines as short as possible.

· The integral base of the GS Outdoor model is designed to mount on a curb. The curb must be built to structurally support the entire weight of the humidifier when in operation. Required curb dimensions are given in Figure #16 . · Gas lines are to be routed to the outside connection on the right side near the back of the unit. The installation of a sediment trap and a certified manual shut-off valve are required outside of the unit.
Figure #18 GasPiping · Each vent length and the rain cap have a built-in mechanical locking band and gasket. Simply push together each component to the stop bead, which provides an air & water-tight seal. Then tighten the integrated locking band on each component to complete the installation of the exhaust venting. · The rain cap must extend at least 2 feet above any ridge within 10 feet of the unit. The exhaust venting can be extended using additional vent lengths purchased from Nortec.
Figure #22 Drain Connection FILL WATER SUPPLY LINE · Each unit is supplied with a ½” NPT male connection to the fill valve. Refer to Figure #21 for connection details. A minimum fill rate of 10 l/min (2.6 gal/min) is required for all unit sizes. Allowable pressure range is 30-80 psig. · Always install a manual shut off within the building to allow isolation of the water to the unit. A union must be installed on the fill line prior to the fill valve to allow for servicing.
STEAM LINES PRINCIPLES OF OPERATION · The steam outlet connection is located at the back of the GS Outdoor unit. Steam hose(s) and clamps are supplied with the unit and are intended to provide a flexible coupling outside of the unit to the building steam lines. See Figure #23. Combustion The combustion system is based on a fully modulating forced draft combustion air blower(s), a negative pressure regulated gas valve, and a 100% premix burner.
Qualified personnel must correct any deficiencies with the installation before commissioning takes place. On initial start-up, the solenoid operated fill valve fills the tank. The water level reaches the backup float first and then the main float. If the backup and main floats do not read the same water level during the operation of the unit, the unit will shut down on a fault. The unit will continue to fill the unit to the top green position.
· At the completion of the float test, the humidifier will begin the combustion sequence by energizing the combustion blowers · At the completion of the float test, the humidifier will begin the combustion sequence and each burner will ignite in sequence · All blowers will run at full output for 30 seconds to pre-purge the combustion chamber.

Figure #25 Site Water Test Kit P/N 1507214 · Close the shut-off valve in the water supply line · Isolate the humidifier from the electrical power supply at the main disconnect switch SCALE MANAGEMENT The gas humidifier will periodically “blowdown” water from the tank to reduce the concentration of total dissolved solids that accumulate during long term operation. Gas Humidifiers are shipped factory set with a blowdown of 25%.
· Conductivity: Measured in micromhos. Follow the directions for the conductivity pen found inside the box. Multiply the digital reading by 1.5. The recommended operating range for conductivity is 0 - 1500 micromhos. Consult the factory is you measure outside these parameters.
