How to Read a Raypak Digital Model Number

[Header]-R[BTU]A-[Ignition][Fuel]-[Material] #[Elevation] — P/B = header type (Polymer standard / Bronze Professional), E/M = ignition, N/P = fuel, C/X = tube material (Copper/Cupro-Nickel). #50/#51/#52 (natural gas) = elevation: 0–2,000 ft / 2,000–6,000 ft / 6,000–9,000 ft. Propane uses #57/#58/#61 for the same tiers.

Elevation match matters for combustion safety and warranty coverage — confirm your installation altitude before ordering.

Sizing Guidance

399,000 BTU is the maximum standard-tier output — best for very large pools, high-demand spas, or situations where recovery speed matters most. If this feels like overkill for your pool size, the 332,000 BTU model saves about $570 with only a modest recovery-time difference.

Copper vs. Cupro-Nickel vs. Professional Series

Standard copper tubing is proven and economical for most installations. If you want this same 399,000 BTU output with commercial-duty construction, the B-R408-EN-X Professional Series is the step up — bronze headers, cupro-nickel, built for heavier duty cycles.

Install Note

Gas heater installation involves gas line sizing, venting, and electrical work — use a licensed professional per local code. Confirm elevation, gas type, and BTU needs with your installer before ordering.
