Cupronickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Cupronickel is highly resistant to corrosion in salt water, because its electrode potential is adjusted to be neutral with regard to salt water. Because of this, it is an ideal choice for swimming pools using salt chlorine generators.
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.

Hi. I am replacing a Teledyne heater for a in ground pool. The heater is indoors and is vented to the outside. I'm looking at the LRZ400EN. I understand this has the electronic ignition and not the mili volt I have now. I will have an electrician wire it. My question is about the venting and if I need a draft hood. I know I need to vent it to the outside. I had hoped to just connect to the venting that's there now. Do I need the draft hoot to be able to attach the venting to the heater?
Yes, I would recommend you sill use the mfg drafthood if you will be using this heater indoors. The correct draft hood for this model is R0499605.If you would like to consult Jandy directly, their contact # is 800-822-7933
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.
