The combustion system utilizes a modulating forced draft combustion air blower, a negative pressure regulator gas valve and a 100% premix burner. On a call for humidity, the combustion air blower starts creating a negative pressure across the valve orifice located at the air inlet. The hot surface ignitor then energizes. The gas

valve opens and the regulated gas/air mixture is forced through the burner ports and is ignited.
Easy Maintenance
The compact stainless steel heat exchanger has large flat surfaces to minimize scale buildup
in the humidifier tank. Scale tends to fall off the exchanger wall to the bottom of the tank, maintaining efficient heat transfer to the water and extending the intervals between cleanings. The smooth stainless steel surface of the tank and removeable heat exchanger are easily cleaned and maintained.
The GS SERIES compact heat exchanger design provides a minimum footprint area where space requirement is an issue.
Operating costs based an electric cost of $0.08 per kWh, natural gas cost $0.75 per therm, full output for 2,000 hours per season. Efficiency of electric unit is 97% and efficiency of gas unit is 82%. Costs do not include electric peak demand charges.
Compact removeable heat exchanger. 105 lbs/hr of clean steam.
