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.

￿GS Outdoor models can develop steam pressures up to 12”w.c. to overcome duct and steam line pressures. Pressures above 12”w.c. will cause steam to exit through the drain line.

￿Steam lines can be routed to an air handler on the roof or pipe chased (external to the unit) through the rooftop to enter the building.

￿All steam lines must be insulated to reduce losses.

￿For steam line installation guidelines, consult the distribution system installation manual (Steam Distributor Installation Manual Form #XX-231 and SAM-e Short Absorption Manifold Form #XX-249).

PRINCIPLES OF OPERATION

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. On a call for humidity, the combustion air blower(s) starts and creates a negative pressure(s) across an orifice located at the air inlet. The blower is energized to purge the system, then the hot surface ignitor is activated. During this time the electronic ignition module does a diagnostic check of safety systems including the air proving switch which senses the negative pressure at the air inlet orifice. After the function of the safety systems has been verified, the gas valve(s) will open and the gas/air mixture is ignited by the hot surface ignitor. If a flame is sensed by the flame sensor, the gas valve(s) remains open and combustion continues. If a flame is not sensed, the above sequence is repeated to a maximum of three times after which the ignition module will lock out. The gas valve(s) maintains a constant ratio air to gas independent of blower speed or external conditions. This air and fuel is thoroughly mixed in the blower(s) and then forced through the burner ports where ignition occurs.

Hot products of combustion are forced through a baffle inside the heat exchanger and then vented outside. The heat exchanger has a large flat surface to minimize scale build-up and promote scale shedding to the bottom of the tank. This self-cleaning

action helps to maintain the efficiency of the heat exchanger while the smooth surfaces allow for easy cleaning when necessary.

Steam line (Insulation recommended)

The GS 100 has a single removable combustion chamber/heat exchanger. The combustion system is duplicated on larger units with multiple chambers inside a common tank.

WATER MANAGEMENT

The GS Series of humidifiers is equipped with a unique float chamber water level monitoring device. Two magnetic floats (one is a backup) measure 5 different water levels in the humidifier for proper operation. The float chamber and board are located away from the boiling action to increase reading accuracy and reduce mineral build-up since it is not in the boiling water. The float chamber is connected to the tank under the water level and above the water level to ensure equalization of pressure between the tank and float chamber. In addition, cooling water is introduced in the float chamber to reduce scale build-up. The unit also includes an internal 1” air gap and a vacuum breaker to prevent siphoning effect.
