Benefits
The Raypak 009843 heater gives pool owners dependable natural gas heating with simple millivolt operation. The standing pilot and mechanical thermostat design does not rely on the same external electrical connection required by electronic ignition models, making it useful for select installations where basic mechanical control is preferred.
The polymer header design helps resist corrosion in pool environments, while the copper fin tube heat exchanger provides dependable heat transfer for residential pool and spa use. The #52 high-altitude configuration is designed for installations between 6,000 and 8,999 feet, so elevation must be confirmed before ordering.
