With 60 years experience as the No. 1 selling brand of pool heaters – Jandy’s new Legacy Heater is designed for today’s discerning market. Available in two models, the Legacy LRZE (electronic ignition) heater features a technologically-advanced dual-thermostat control, and the LRZM (millivolt ignition) model features a single control with easy on/off switch.
Whichever model you select, it’s sure to provide years of dependable service. With our industry-leading 24-point quality check system, you can depend on Legacy’s performance and reliability year after year, season after season.
The Pool Sizing Guide shows the maximum pool surface area our Legacy models will heat based on the temperature difference between the air temperature during the coldest month the pool is used and the desired pool temperature. Figures are based on average wind conditions and average pool depth.
The Spa Sizing Guide details the time required for each model to raise spa temperature by 30°F.
Replacement for Jandy Lite2™ heaters.

I was comparing the two types millivolt and electronic Does the milivolt need any electric connection? And the electronic ignition, can I just hook that to regular 110 outlet?
In reference to the 110V question, this is taken straight from the manual "The heater comes factory-wired intended for use with 240 Volt, 60 Hz AC field electrical supply. To use 120 Volt, 60 Hz AC requires rewiring of the heater." As for the millivolt question " This design has a constant pilot, sitting just below a small generator. This generator uses the heat of the pilot flame to generate small amounts of power (milli-voltage, or thousands of a volt). This trickle of power is then used to operate the rest of the system. The pilot operates at about 500 BTUH.The advantage of using millivolt ignition is that no electrical power needs to be supplied to the heater. The heater can therefore be located in areas where no electrical service is readily at hand, or where it would be prohibitively expensive to provide electric service.
What is the difference between an Electronic and Millivolt ignition?
The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.
Will a gas heater operate at the low speed of a dual speed motor?
Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.
