Product details
This is Raypak's Digital natural gas pool and spa heater in the 406A size, 399,000 BTU/hr input, jetted with the #52 orifice for installations from 6,000 to 9,000 ft. Raypak's model is the P-R406A-EN-C #52, part number 009849, which Raypak's Raypak to Rheem cross reference pairs with the Rheem model P-M406A-EN-C #52, 009973.
Why the orifice matters
Raypak sells the same heater jetted for three bands: #50 for 0 to 2,000 ft, #51 for 2,000 to 6,000 and #52 for 6,000 to 9,000, each under its own part number. Order the band that matches the installation address. This one covers 6,000 to 9,000 ft.
The heater
Polymer headers with the ProTek Shield module, a straight copper fin tube heat exchanger, digital IID ignition with no standing pilot, and a digital LCD that sets the temperature and reads out diagnostics. Raypak's Unitherm governor prevents condensation, the self adjusting burner compensates for gas pressure changes, and the heater plumbs directly to PVC and can sit on a combustible surface.
Power and connections
120 or 240 VAC, single phase, at 4 A or 2 A. Water connections are 2 inch slip, the gas connection 3/4 inch NPT, and the cabinet is 29 inches wide. At the rated 82 percent thermal efficiency the heater puts about 327,180 BTU/hr into the water.
