Jandy Legacy 250 BTU igniter replacment Falt type not spriral

My “Jandy Legacy 250 BTU”, was wired factory for 240v power source. Does that matter when I replace my hot surface igniter( Flat one not spiral)?  The ignition port igniter has a 120v input and a 240v input? Yet the manual shows each should supply no more than 50v? They shipped a spiral igniter that I sent back as mine requires a flat igniter. The spiral igniter I returned had a 120v tag on one wire? So my question is what port do I plug the surface igniter into the 120 or 240 v port on the ignition port igniter? I find no help on the internet and from the wholesalers? Totally confused and the pool techs have no clue. My guess is using the 240 port since the Voltage is Identical for a 120v powered heater and a 240v factory wired power source. The transformer corrects for that I’m thinking??? Boy! Look at the manual and you will see the two possible wiring configurations. Again My heater is connected to a 240v source into the unit. email Geolab104@gmail.com
