Frequently Asked Questions
What does ASME certification mean and do I need it?
ASME is a pressure vessel standard. Most commercial, municipal, hotel, and HOA pools are required by code or by their inspector to use an ASME certified heater. A private residential pool usually is not.
Why bronze headers and cupro-nickel together?
This is the durability build. Bronze headers withstand continuous commercial duty, and cupro-nickel tubes resist the corrosion that copper suffers in salt, low pH, and heavy bather load conditions.
Why does the orifice number matter?
The orifice sets gas flow for your altitude. A #50 covers 0 to 1,999 ft. The 017404 is the same heater with a #51 orifice for 2,000 to 5,999 ft, and the 017408 uses a #52 for 6,000 to 8,999 ft.
What does B-R266A-EN-X mean?
Raypak's model code. B is the Professional ASME series, R266A is the 266,000 BTU chassis, E is electronic ignition, N is natural gas, and X denotes the cupro-nickel heat exchanger.
What size body of water does this suit?
Mid-size commercial pools, therapy pools, and large residential installations. Commercial sizing depends on bather load, surface area, and overnight covering, so have it engineered rather than estimated.
Does it need professional installation?
Yes, and commercial installations typically require permitting and inspection in addition to a licensed installer.
