Quick overview

  • ASME rated Built to the ASME standard, which is what commercial installations and many public codes require.
  • Cupro-nickel heat exchanger Specified for chlorinated and salt water pools, where a standard copper exchanger has a harder life.
  • Bronze header The bronze header pairs with the cupro-nickel exchanger for corrosion resistance at the water connections.
  • Digital IID control Digital controls with intermittent ignition device firing, so there is no standing pilot.
  • ProTek Shield A sacrificial module that takes the corrosion instead of the heat exchanger, and is designed to be easy to replace.
  • Raypak 017401 The part number for the B-R336A-EN-X, the 0 to 2000 ft elevation natural gas version.

Product details

The Raypak B-R336A-EN-X is an ASME rated digital natural gas pool and spa heater with a bronze header and a cupro-nickel heat exchanger, part number 017401. The source lists its input as 336,000 BTU in the model description and 333,000 BTU in the product copy.

Why the ASME build

ASME construction is what commercial pools and many public and municipal installations are required to use. It is a heavier specification than a standard residential heater, matched here with a digital control set and intermittent ignition rather than a standing pilot.

Bronze and cupro-nickel

The header is bronze and the heat exchanger is cupro-nickel. That pairing is chosen for water that is aggressive: heavily chlorinated pools and salt systems both shorten the life of a plain copper exchanger, and this combination is built to last in those conditions.

ProTek Shield

Raypak adds a ProTek Shield module that is designed to absorb the corrosion that would otherwise reach the heat exchanger. It is meant to erode: visible wear on the shield is a sign the protection is working, and the module is built to be swapped out without major disassembly.

Before you order

This is the 0 to 2000 ft elevation natural gas version. The source also references a related model, C-R336A-EN-X, part 010200, so order by the model number on your specification rather than by BTU alone.
