Raypak Digital ASME Propane Pool Heater, 199.5K BTU, Cupro-Nickel Heat Exchanger, Bronze Headers, 0 to 2,000 ft, B-R206A-EP-X #57, 017411

The Raypak B-R206A-EP-X #57, part number 017411, is the 206A size of Raypak's Digital ASME pool and spa heater: 199,500 BTU/hr input on propane, 2 inch bronze headers, a cupronickel fin tube heat exchanger and an orifice set for installations from 0 to 2,000 ft.

The ASME build

The B at the front of the model number is Raypak's code for bronze ASME headers, which give the heater the strength commercial code requirements call for. It ships with a 125 psi pressure relief valve, carries the ANSI Z21.56 design certification, and can be installed indoors or out, directly on a combustible surface. Whether a pool needs an ASME heater is for the local code and the inspector to say.

Heat exchanger and protection

The tubes are cupronickel, the X at the end of the model number. Raypak uses a straight tube design with no bends or helical coils, and fits the ProTek Shield module at the inlet, which Raypak engineers to take the brunt of the corrosion that occurs over time and recommends for chlorinated and salt water pools.

Controls

The digital LCD sets the temperature and the heater's settings, and the microprocessor shows a diagnostic readout while it monitors operating status. The control ties into an existing remote system, and the self adjusting burner compensates for gas pressure changes. Power is 120 or 240 VAC, single phase.

Before you order

Raypak sells the 206A ASME heater under separate part numbers by fuel, exchanger and elevation band. This one is propane, cupronickel, 0 to 2,000 ft. At Raypak's rated 82 percent thermal efficiency it puts about 163,590 BTU/hr into the water.
