Raypak Digital 336K BTU Natural Gas Pool Heater - ASME Cupro Nickel - B-R336A-EN-X | 017401

The ultimate heavy-duty heating solution for commercial saltwater environments. The Raypak B-R336A-EN-X is a premium, high-capacity natural gas heater engineered to meet the rigorous American Society of Mechanical Engineers (ASME) safety and construction standards. Designed specifically for demanding commercial applications like hotels, public pools, and swim schools, this 336,000 BTU unit features the necessary certifications to pass strict local building codes.

The 017401 model goes a step further by upgrading the internal components for aggressive water chemistry. Equipped with rugged Bronze Headers and a professional-grade Cupro-Nickel heat exchanger, it is built to survive the continuous operation and corrosive effects of commercial saltwater pools where standard heaters would quickly fail.

Features

ASME Certified Construction: This heater is built and pressure-tested to meet strict ASME safety codes. It features a thicker heat exchanger wall and a specialized pressure relief valve, making it legally compliant for use in public and commercial pool installations.

Professional-Grade Cupro-Nickel Heat Exchanger: Constructed from a premium copper-nickel alloy, this heat exchanger is built to withstand the erosion and corrosion common in saltwater pools and high-bather-load facilities. It offers a significantly longer service life than standard copper under aggressive water conditions.

Corrosion-Resistant Bronze Headers: To meet commercial building codes, this model replaces standard polymer with heavy-duty bronze headers. Bronze provides superior structural strength to handle high-pressure commercial systems and is naturally resistant to chemical degradation.

Robust 336,000 BTU Power: Providing massive thermal lift, this commercial model delivers rapid heat-up times for oversized residential pools or mid-sized commercial spas. It ensures your water reaches the perfect temperature quickly, minimizing downtime for your facility.

Microprocessor-Controlled Thermostat: The intuitive digital display allows for precise temperature management to within one degree. It features built-in self-diagnostics to monitor the system and ensure the heater is operating at peak 82% efficiency.

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.

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 second layer of defense for saltwater pool systems.

Non-Corrosive Cabinet Construction: The unit 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: This ASME model is typically mandated for public and commercial pool installations. It must be installed by a licensed commercial HVAC or pool professional to ensure proper gas line sizing, correct drafting, and adequate venting for safety and strict warranty compliance.
