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. Refer to the Gas Piping section of this manual. LOCATING AND MOUNTING GS Series humidifiers are designed for floor mounting or on a GS Stand (optional).
· DO NOT mount humidifiers in an area where freezing may occur. · If humidifiers are mounted on a roof, a properly ventilated, temperature controlled, (above freezing), weatherproof enclosure must be used. · DO NOT mount humidifiers on vibrating surface.
upstream of the gas supply connection to the appliance. 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.
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. Listed below are instructions for both venting systems, followed by specific requirements for each system.
-8- Trap UL Listed Cap Required Condensate tee and trap must be installed. T ake the condensate to a floor drain or a condensate pump. B type double wall vent with double wall connectors required for category I appliances.
· For any vent lengths over 20 feet long, insulate the vent pipe to reduce the amount of condensate that could form in the flue gases. · When the venting passes through a cold area, or location that has large amounts of air passing over the venting, it should be insulated to prevent condensation from forming inside the venting.
· Vent pipe must be secured with hangers or pipe straps · All horizontal runs must be adequately supported with hangers or straps to prevent sagging.
· 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. · This venting category cannot be used in direct vent applications.
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.

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.

EXHAUST VENTING - OUTDOOR UNITS · All required exhaust venting is provided with each GS Outdoor model, by Nortec, including rain cap and storm collar. All venting components external to the unit are shipped with the unit and must be installed on site.
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.
STEAM LINES · 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.
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.
· At the completion of the float test, the humidifier will begin the combustion sequence by energizing the combustion blowers · All blowers will run at full output for 30 seconds to pre-purge the combustion chamber.

· 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.
· 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.

· Ensure that power is switched on again during periods of demand. · The GSTC model of the Gas Steam humidifier includes a pre-cleaning sequence feature. When activated (through the keypad), the unit will flush the humidifier, refill with cold water, and flush again reducing the scale accumulated at the bottom of the tank.
The switch board must be replaced into the same position as before cleaning and the tie -wrap must be used to hold the float chamber in position. SERVICING THE UNIT Caution: Disconnect power before servicing this appliance. Caution: Label all wires prior to disconnection when servicing controls.
