Quick overview

  • ASME rated The ASME build is what commercial and code driven installations call for.
  • Cupro-nickel exchanger Chosen for aggressive water, high flow and heavy duty cycles.
  • Digital LCD control Temperature and heater settings are set and read from the LCD.
  • Continuous self monitoring The microprocessor watches operating status and gives a diagnostic readout, so a fault points at itself.
  • Unitherm governor Holds return water temperature up to keep condensation off the exchanger, which is a common killer of gas heaters.
  • Small footprint, high wind rated Compact for the space it makes, and built for reliable firing in wind.

Product details

The Raypak B-R406A-EN-X is an ASME rated natural gas pool heater listed at 399K BTU, built with a bronze header and a cupro-nickel heat exchanger for elevations from 0 to 2000 ft.

Control and diagnostics

A digital LCD handles temperature and heater settings. Behind it, a microprocessor monitors operating status continuously and puts a diagnostic readout on the display, which turns a service call from guesswork into reading a code.

Built against the two things that kill heaters

Condensation and water chemistry. The Unitherm governor keeps return water temperature high enough to stop condensation forming inside the exchanger, and the cupro-nickel exchanger takes aggressive water and heavy duty cycles better than plain copper.

On site

The cabinet has a small footprint for the output, and the burner design is rated for high wind reliability. Gas sizing, venting and clearances have to be checked against the manufacturer instructions before it is fired.
