Ok I would like to know if I can run a small gen. aprox 3000 watt 3500 surge on my englander 25 pdvc? I have a cyber power batt backup with surge protection on it now just enough power for about 15 min run time and the shutdown procedure. I woould like to use the small gen. and the batt backup in between to keep the heat on but I was told the gen. can take out the circuit board and I reallly don't want that to happen. Any info would be great. Thanks
