The Legacy heater does not require an external source of electrical power to operate. The power for the gas valve and safety circuit are generated by a thermopile. The thermopile generates a millivolt signal when heated by the pilot flame. Figure 16 in the manual here shows the internal electrical wiring diagram and schematic of the heater.
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.
