SKU JXI400N Categories , Brand:

The Jandy JXi 400 natural gas pool and spa heater (JXI400N) delivers 399,000 BTU/hr of input in a compact cabinet for residential equipment pads. This copper heat-exchanger model is intended for a properly sized natural gas supply. Its three-port header offers flexible plumbing connections for new installations and selected MasterTemp or Max-E-Therm replacements.

Rated thermal efficiency is 84%, with a specified operating water-flow range of 30 100 GPM. The low-NOx combustion design combines a stainless-steel burner with copper finned exchanger tubes. A thermal regulator helps manage water temperature through the exchanger. The unit weighs 126 lb unpackaged, and the cabinet is approximately 22.1 by 21.6 by 26.5 inches. Allow additional space for plumbing, venting and required service clearances.

The package includes the heater, universal water-connection unions, the unused-inlet cap and O-ring, a sweep elbow and installation documentation. Gas piping, site-specific vent components and installation materials depend on the project. The standard model does not include the optional VersaFlo bypass kit. AquaLink integration supports coordinated equipment operation when compatible automation is installed.

This model suits homeowners who want gas-fired pool or spa heating with a compact footprint and convenient service access. Our Jandy dealer team in Palm Beach County can check fuel type, sizing and installation requirements.

Available for pickup at our Jupiter, FL showroom or free local delivery in Palm Beach, Martin and St. Lucie counties with full manufacturer warranty. Professional installation available.
