1. I drained all the old boiler fluid out and replaced with green automotive antifreeze and distilled water
2. I put in new stainless swing check valves
3. I put the radiator pressure tester on the filler neck and pumped to 15 pounds and jumped the relays on the pumps to prime them. Then refilled with antifreeze. I had to repeat this process several times to get it totally full. Here are some pics
