Frequently Asked Questions - Legacy Jandy
What type of gas does the Jandy Legacy heater use?
The Jandy Legacy can be configured for natural gas or propane. Check the model number or conversion kit.
How do I clean the heat exchanger?
Turn off power and gas, remove the top cover, and use a vacuum or brush to remove soot and debris. Refer to manual for detailed steps.
What is the typical lifespan of a Jandy Legacy heater?
With proper maintenance, the heat exchanger can last 10-15 years or more. Regular cleaning and water chemistry management extend lifespan.
Why is my heater not igniting?
Check for gas supply, ignition electrode gap, and pressure switch. Also ensure the pool pump is running (flow switch).
Can I install the Legacy heater indoors?
No, it is designed for outdoor installation only due to combustion venting requirements. Indoor use would require special venting.
How do I reset the high-limit switch?
Locate the red reset button on the high-limit thermostat. Push it firmly until it clicks. If it trips repeatedly, check water flow or scaling.
What water flow rate is required?
Minimum 30 GPM for most models. Use a flow meter to verify; low flow can cause overheating and shutdown.
How do I winterize the heater?
Drain all water from the header and heat exchanger using the drain plugs. Disconnect gas and electrical if storing.
What does error code 'E01' mean?
E01 typically indicates ignition failure. Check gas, spark, and flame sensor. If persistent, call a technician.
Where can I find replacement parts?
Jandy dealers or online parts store. Use model number and serial number to identify correct parts. Common parts: igniter, thermistor, pressure switch.
