Raypak Digital 336K BTU Natural Gas Pool Heater - Copper - P-R336A-EN-C | 009222

The Raypak P-R336A-EN-C delivers a robust 336,000 BTU output using an advanced digital electronic ignition system. Designed to provide rapid heat-up times for oversized pools and attached spas, this natural gas heater combines legendary mechanical reliability with modern, intuitive controls.

The 009222 model is equipped with a standard copper heat exchanger and durable polymer headers, delivering consistent and efficient everyday performance. It is the perfect blend of power, precision, and longevity for freshwater backyard environments.

Features

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, making troubleshooting fast and simple.

Reliable Electronic Ignition: Features a robust spark-to-pilot ignition system that only lights when there is a call for heat. This eliminates the gas waste of a standing pilot light and ensures the heater remains functional even in high-wind conditions.

Standard Copper Heat Exchanger: Built with high-quality integral copper fin tubes, this heat exchanger provides maximum heat transfer and 82% thermal efficiency. The single-piece header design ensures smooth water flow and minimizes the risk of internal leaks.

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.

ProTek Shield Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), providing a critical layer of defense for the unit's most vital parts.

Non-Corrosive Cabinet Construction: The heater is housed in a polyester-coated, galvanized steel cabinet built to resist rust and UV fading. Its wind-resistant design ensures the burner stays functional even in exposed or coastal outdoor environments.
