Jandy JXiQ ASME Pool & Spa Heater — 260,000 BTU/h Natural Gas — Cupronickel | JXIQ260NS

260,000 BTU/h input; Natural Gas; 83% thermal efficiency; cupronickel heat-exchanger tubes / bronze headers; 30–100 GPM; 75 PSI maximum working water pressure; 2-inch water connections; cabinet dimensions in Width × Depth × Height order: 21.6 × 22.1 × 26.5 inches (excludes vent/header/plumbing projections and required installation clearances); 163 lb manufacturer-listed product weight.

The ASME heater, two connector flanges, two 2-inch sleeves, two 2-inch gaskets, four flange bolts, four flange washers and the 75 PSI pressure-relief valve kit identified in the ASME manual package table. Field gas/electrical work, venting, water plumbing and discharge piping are separate. Factory VersaFlo and the standard polymer-header anode are not included.

Choose JXIQ260NS for its natural gas supply, 260,000 BTU/h input, cupronickel heat exchanger and bronze header. This is the ASME configuration. Local commercial/public-pool requirements and the exact equipment label must still be verified; an ordinary polymer-header model is a different unit.

Auto-sensing 115/230 VAC, 60 Hz input as described in Section 6 of the JXiQ manual (specification table uses nominal 120/240 VAC). Electrical wiring and grounding require the matched professional-installation instructions.

The manufacturer specifies 30–100 GPM through the heater. A manual external bypass is required when pump flow exceeds the allowed maximum. The internal thermal-regulator/bypass arrangement is not a factory VersaFlo feature on this ordering code. Maximum working water pressure is 75 PSI for this bronze-header configuration. Flow, relief protection and the pressure limits of all system components must be checked together.

The manufacturer lists a 7-inch Category I connection for model size 260 and a 4-inch Category III connection. A vent adapter alone is not a complete approved venting system. Natural-gas installation classifications include indoor, outdoor and covered-shelter use when all specified provisions are met. A qualified installer must verify combustion air, vent type, equivalent length, termination, clearances, gas supply and local requirements.

The cabinet/body dimensions are 21.6 inches wide × 22.1 inches deep × 26.5 inches high. The Dimensions field lists those three values in that order. Vent, header and plumbing projections, the supporting pad and service/combustible clearances are additional. Use the drawing for the exact installed revision; body dimensions are not the total installed footprint. Manufacturer-listed product weight is 163 lb; shipping/package measurements are separate.

JXiQ provides an expanded display, low-gas-pressure monitoring and temperature-rise diagnostics. Bluetooth is used with the Fluidra Pro app for professional diagnostics. App-based homeowner remote control requires compatible separately installed AquaLink automation; Bluetooth diagnostics alone are not Wi-Fi pool control.

The R0731100 4-inch exhaust adapter and R0724600 3-inch intake kit are separate installation accessories; JXIGUARD is a separate control-panel lock box. The matched 75 PSI ASME replacement relief-valve kit is R0336102. The polymer-header anode R0965100 is excluded from this ASME application.

Jandy’s current limited warranty excludes equipment purchased through the internet or an e-commerce site, apart from the stated exceptions for parts, pool accessories and valves under 3 inches. This complete heater is not a replacement-part exception. The general heater/commercial terms do not establish an unconditional warranty for an online heater purchase. Review the full manufacturer statement before purchase. Qualified licensed installation/service where required, first-retail-purchaser/original-site limits, geography and the stated exclusions apply.

Use the JXiQ Installation & Operation Manual, current JXiQ model specifications, 2026 heater ordering table and current Jandy Limited Warranty, H0333803 Rev AB. The manufacturer EnergyGuide index identifies the appropriate 83% label. Follow the exact model, header, fuel and installed revision.
