Product details
The Raypak B-R406A-EP-X is the 399,000 BTU propane gas pool and spa heater, built to ASME with a digital IID control, a bronze header and a cupro-nickel heat exchanger, and rated for installation from 0 to 2000 ft elevation. Raypak part number 017414.
Why this build
The 400 size Raypak is offered in several configurations, and this is the heavy end of the range. ASME certification is what many commercial and code driven installations call for. The bronze header and the cupro-nickel exchanger are the corrosion resistant pairing, chosen for salt water pools and for water chemistry that would chew through a standard copper and polymer build.
ProTek Shield
Raypak fits this heater with ProTek Shield, a module that protects the heat exchanger and extends its life. It is engineered to absorb the corrosion that occurs naturally over time, so erosion of the shield itself is a sign that it is working. Raypak lists it as suitable for chlorinated and salt water pools, compact, and easy to replace.
Ordering and installation
This heater ships by freight. Gas heaters of this size need a correctly sized propane supply line, adequate combustion air and a compliant vent, so have the installation reviewed by a licensed gas fitter before the unit arrives. Confirm the full model string against your specification, since the natural gas, header and elevation variants are all separate part numbers.
