Raypak 017399 Digital ASME 206A Natural Gas Pool and Spa Heater, 199,500 BTU

Model B-R206A-EN-X #50 ASME | Order # 017399 | Cupronickel heat exchanger, bronze headers | Built for 0 to 2,000 ft elevation

The Raypak Digital ASME 206A is the commercial version of Raypak's Digital atmospheric gas heater, rated at 199,500 BTU per hour on natural gas. Its heat exchanger is ASME-certified and National Board registered, with bronze headers and cupronickel fin tubes, and a 75 PSI pressure relief valve comes in the carton. Item 017399 is the natural gas, cupronickel version built for installations from sea level to 2,000 ft.

✅ Made for:

• Use: commercial pools and spas, and other installations where an ASME-certified heater is required.
• Fuel: natural gas only. Raypak lists the propane version as item 017411.
• Elevation: sea level to 2,000 ft (burner orifice #50). Raypak lists item 017403 for 2,000 to 6,000 ft and item 017407 for 6,000 to 9,000 ft.
• Heat exchanger: cupronickel tubes. The same heater with copper tubes is Raypak item 017371.
• Outdoor installation as shipped, using the stackless top packed with the heater. Indoor installation needs Raypak indoor stack kit 009838 and a vent to the outside.
• Pump flow between 20 and 100 GPM. Above 100 GPM Raypak calls for an external bypass valve.
• This is an atmospheric heater, not a Low NOx model. Raypak's Low NOx ASME heaters are the 207A to 407A series.

• Raypak limited warranty for ASME pool and spa heaters: one year parts and labor.

📌 Good to know:

• Raypak rates the input for elevations up to 2,000 ft and reduces it 4% for each 1,000 ft above sea level beyond that, so order the version built for your elevation.
• Some jurisdictions require a flow switch on ASME installations. Raypak offers kit 015889F (flange connection) or 015890F (NPT connection) for that.
• On ASME units a high-limit trip is a manual-reset fault, cleared with the MODE button.
• The ProTek Shield is a wear item and is not covered by the warranty. Raypak says to replace it when its weight has dropped to about 40% of the original.
• Salt chlorinators and chemical feeders must be plumbed downstream of the heater. Raypak's water chemistry table allows up to 4,500 ppm salt.
• To move the water connections to the other side on an ASME model, Raypak says to call the factory representative for instructions.
• Gas, venting and electrical work must be done by a qualified installer or service agency. Raypak's warranty applies to heaters installed by a licensed service provider.

Gas, venting and electrical work must be done by a qualified installer and meet local codes.
