Description

The Raypak 017374 is the 406A ASME digital natural gas heater built for high-demand pool and spa applications. This model uses bronze headers, digital ignition, and a commercial-grade ASME pressure vessel for installs where durability and code compliance matter. Its strong heat output makes it a solid choice for larger bodies of water or projects that need faster recovery without stepping into oversized equipment. For commercial pads, shared amenity pools, and demanding residential builds, this heater is built around performance first.

Pro Tip

Before ordering, confirm altitude, venting method, gas supply capacity, and electrical requirements. Use the proper Raypak union kit at install, and consider adding the ProTek Shield kit for added internal corrosion protection on compatible digital heater setups.
