Raypak Digital 406K BTU Natural Gas Pool Heater - Copper - P-R406A-EN-C | 009223

The Raypak P-R406A-EN-C (High-Altitude version) is the most powerful residential heater engineered specifically for installations located between 2,000 and 6,000 feet above sea level. At these elevations, thinner air can cause standard high-BTU heaters to burn inefficiently, leading to carbon buildup and reduced lifespans. This specialized 406,000 BTU model features factory-set orificing and pressure adjustments to ensure a clean, powerful, and efficient burn in mountain environments.

The 009223 model provides the fastest possible heat-up times for large inground pools and massive spa combinations, ensuring that even in high-altitude climates, your water is ready exactly when you want it.

Features

Certified High-Altitude Performance: This unit is factory-configured to maintain an optimal air-to-gas mixture at elevations up to 6,000 feet. This prevents the "sooting" and frequent pilot outages that commonly plague standard high-output heaters installed in high-altitude regions.

Maximum Heating Speed: With 406,000 BTUs of raw power, this heater is designed for rapid temperature gains. It is the perfect solution for "on-demand" heating of large attached spas or for maintaining comfortable swimming temperatures in very large residential pools.

Microprocessor-Controlled Thermostat: The intuitive digital display allows you to set your pool and spa temperatures independently to within one degree. The system also features constant self-diagnostics to alert you to any operational issues, ensuring your heater runs smoothly throughout the season.

Reliable Electronic Ignition: Features a robust "spark-to-pilot" ignition system that only lights when there is a call for heat. This eliminates the need for a standing pilot light, saving on gas costs and preventing blow-outs in the gusty, unpredictable conditions often found at higher elevations.

Standard Copper Heat Exchanger: Built with high-quality integral copper fin tubes, this heat exchanger provides maximum heat transfer and thermal efficiency. The single-piece header design ensures smooth water flow and reduces the risk of internal leaks.

Corrosion-Resistant Polymer Headers: The glass-reinforced polymer headers are specifically designed to resist the corrosive effects of pool water and chemicals. This modern construction also makes the unit lighter and easier to maneuver during installation on mountain equipment pads.

PolyFlo Integrated Bypass: Raypak’s patented bypass design balances the water flow through the heat exchanger automatically. This prevents condensation and scale buildup, protecting the heater's internal components from premature wear and maintaining peak efficiency.

ProTek Shield Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), which is a leading cause of heater failure in modern pools.

Notes

Verify Local Elevation: Installing a high-altitude heater at sea level, or a sea-level heater at high altitude, can lead to dangerous operation and will void the manufacturer’s warranty. Please confirm your site’s elevation before purchase. Due to the high BTU rating, this unit requires professional installation to ensure correct gas line sizing and venting.
