Product Overview

The Raypak 407A ASME Digital Natural Gas Heater | 017712 is a heavy-duty pool and spa heater designed for commercial, semi-commercial, and demanding residential applications. With a powerful 399,000 BTU input, this heater provides fast heat-up performance for larger pools, spas, and high-demand aquatic systems.

This ASME model is built with bronze headers and a cupronickel heat exchanger, making it a strong choice for tougher water conditions, high-use pools, saltwater pools, and applications where added durability is required. The Low NOx design supports cleaner combustion, while the digital control system provides easy temperature adjustment and onboard diagnostics.

The B-R407A-EN-X #26 configuration is designed for natural gas and commonly listed for 0–5,000 ft elevation applications. It also includes the ProTek Shield module, which helps protect the heat exchanger from corrosion-related damage caused by stray current and aggressive water conditions.

Installation Notes

This heater must be installed by a qualified pool professional, licensed gas technician, or licensed contractor as required by local code. Proper installation requires correct natural gas supply sizing, electrical wiring, bonding, grounding, water flow verification, plumbing layout, combustion air, and venting where required.

Before installation, confirm that the fuel type is natural gas, the #26 elevation configuration is correct for the installation location, and the gas supply can support a 399,000 BTU heater.

Water chemistry must be maintained within recommended ranges to protect the cupronickel heat exchanger, bronze headers, and connected pool equipment. Improper water balance, poor flow, or incorrect installation can reduce heater life and may void warranty coverage.
