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

332,000 BTU is for larger residential pools, spas needing quick heat-up, or cooler climates where recovery speed matters. If 266,000 BTU already covers your pool size, that tier saves roughly $450.

Copper vs. Cupro-Nickel vs. Professional Series

Standard copper tubing is proven and economical for most installations. Cupro-nickel resists corrosion better in high-salt or poor water chemistry environments. The Professional Series is Raypak's commercial-duty tier for heavier use.

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.
