Raypak Digital 336K BTU Natural Gas Pool Heater - ASME Bronze Headers - B-R336A-EN-C | 017373

The Raypak B-R336A-EN-C is an elite heating solution engineered to meet the rigorous American Society of Mechanical Engineers (ASME) safety and construction standards. Featuring rugged bronze headers, this 336,000 BTU (332.5K nominal) unit is specifically designed for commercial applications such as hotels, health clubs, and public swim schools where local building codes require ASME-certified equipment.

The 017373 model delivers reliable natural gas heating power with the added durability of non-corrosive bronze internals, ensuring it can handle the high flow rates and continuous operation common in commercial environments.

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.

Reliable 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, even in cooler climates.

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.
