Pool Heater Experts · Mazgan Inc.
Jandy JXi, LXi, and related systems need coordinated checks of combustion, heat transfer, ignition, sensors, water flow, bypass operation, and control history.
Technical guidance
Dust, corrosion, insects, nesting, moisture, and burner deterioration affect ignition and flame stability.
Restricted exchanger surfaces, poor flow, bypass issues, scaling, and sensor problems may contribute to high-temperature faults.
The control request, blower where equipped, pressure proving, igniter, gas valve command, flame signal, and lockout history should be reviewed.
Pump operation, filter pressure, valve position, bypass components, pressure switches, and water temperature rise affect safe operation.
The heater should complete a stable ignition cycle and operate without abnormal sound, odour, flame behaviour, or recurring faults.
