Raypak Digital 406K BTU Natural Gas Pool Heater - ASME Bronze Headers - B-R406A-EN-C | 017374

The Raypak B-R406A-EN-C is a heavy-duty heating solution engineered to meet the rigorous ASME (American Society of Mechanical Engineers) safety and construction standards. Featuring rugged Bronze Headers, this 406,000 BTU unit is specifically designed for commercial applications—such as hotels, health clubs, and high-end residential projects—where local building codes require ASME-certified equipment.

The 017374 model delivers massive heating power with the added durability of non-corrosive bronze internals, ensuring it can handle high flow rates and continuous operation with ease.

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 pressure relief valve, making it legal for use in commercial and public pool installations.

Corrosion-Resistant Bronze Headers: Unlike standard polymer headers, these heavy-duty bronze headers provide superior strength and are naturally resistant to the corrosive effects of pool chemicals and high-velocity water, significantly extending the unit's lifespan.

Unmatched 406,000 BTU Power: As the largest residential/light-commercial model in the lineup, this heater provides the fastest possible heat-up times. It is the ideal choice for large Olympic-sized residential pools or high-occupancy commercial spas.

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 and ensures the heater remains functional even in high-wind conditions.

PolyFlo Integrated Bypass: Raypak’s patented bypass design balances 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 an essential defense in modern pool environments.
