Review on Suburban SW6DEL Water Heater - DSI/Electronic, 6 Gallon, Model 5240A by Cody Mckechnie

SW6 DE replaced by SW6DEL. "L" indicates a relay. This is the relay that has 120 AC connected to it. So it comes with an extra DC power cord (orange) that goes to where the 120 volts is connected. It has a yellow wire that goes to ground. I ordered the 232882 Suburban Wall Switch which has an extra switch for this relay. An additional switch was powered by 12 volts DC and reached for the orange wire. Runs on AC and propane gas.
