Raypak Digital 336K BTU Natural Gas Pool Heater - Cupro Nickel - P-R336A-EN-X | 014940

The Raypak P-R336A-EN-X is a professional-grade heating solution designed for large residential pools and commercial-scale spas. This 336,000 BTU natural gas model is upgraded with a high-performance Cupro-Nickel heat exchanger, providing the highest level of durability against the damaging effects of saltwater systems, poor water chemistry, and high-velocity water flow.

The 014940 model ensures your large body of water reaches the perfect temperature quickly while providing the peace of mind that comes with premium, salt-ready internal components.

Features

Corrosion-Resistant Cupro-Nickel Heat Exchanger: Constructed from a robust copper-nickel alloy, this heat exchanger is specifically engineered to outlast standard copper versions. It offers superior resistance to erosion and chemical corrosion, making it the essential choice for pools equipped with salt-chlorine generators.

Large Capacity Heating Performance: With 336,000 BTUs of power, this heater provides the thermal lift necessary to warm large inground pools rapidly. It is the ideal "bridge" model for owners who want near-flagship performance with a slightly smaller footprint than 400K BTU units.

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 need for a standing pilot light, saving on gas costs and preventing common pilot blow-outs in windy conditions.

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

ProTek Shield Technology: This innovative, replaceable module is designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), providing a critical second 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.

Notes

Professional Setup Required: For safety and to maintain the manufacturer’s warranty, this gas heater must be installed by a licensed HVAC or pool professional. Proper gas line sizing (typically 1.25") and adequate venting are critical for the safe and efficient operation of the 336 model.
