New to the wood boiler life, got married twice in the same year! Once to my wife and once to the OWB... I was just curious on first fill procedure.. can I fill from the return port.. being that it's the lowest point it would be pushing water through the system to the highest point. Plz advise if this is not smart. I read somewhere about hydrolocking by getting water in return line first..
