The Raypak 009243 P-R407AL-EN-C #26 Digital Low NOx Natural Gas Pool & Spa Heater is built for large residential pools and spas that demand fast, high-volume heat recovery. With a 399,000 BTU input, a corrosion-resistant copper fin tube heat exchanger, Low NOx emissions compliance, and Raypak's ProTek Shield protection, this heater is engineered to deliver dependable heating performance year after year in both indoor and outdoor installations.
The cabinet is constructed from polyester-coated, non-corrosive galvanized metal for long-term durability against the elements. Capron resin polymer headers resist rust staining, while the ProTek Shield module helps guard the heat exchanger against premature corrosion, extending the usable life of the unit even in demanding pool chemistry conditions.
Digital intermittent ignition (IID) lights the burners automatically without a standing pilot, and the LCD control panel with smart microprocessor diagnostics gives installers and owners real-time readouts for fast troubleshooting. A 2" PVC threaded union simplifies plumbing connections on new installs and heater replacements alike.
