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.

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.
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.
