Purchased a sauna at Home Depot. The heater that came with it is Advertised as 220v 20 amp. My plan was to plug it into a 240v outlet I have in the garage (though after looking at my panel it is currently going to a 30 amp). When it arrived the heater had no plug on the end and only 3 wires. The schematic included with the heater (BC 23 see picture) shows it is currently wired to 1. Ground 2. Neutral 3. L1 & L2 which are bridged. From my research this is how it would be wired for European use. My question is can I remove the 3 wire cord and the bridge and instead hook it up as 1. Ground 2. Neutral 3. L1 to 120 4. L2 to 120 so I can use a 4 wire US plug? I plan to use an electrician to do the work but so far the 2 places I called didn't seem to know. Appreciate any advice.

If you do that, you will likely end up with the heater running at a quarter of it's designed power.
Most likely for a US style 120/240 supply you need to leave the "L1 and L2" terminals connected together and connect them to one hot from your supply, connect the "N" terminal to the other hot from your supply and leave the neutral conductor from the supply disconnected.
