After your 2nd runnings are drained, fire that kettle up. It shouldn't take long if you already started heating the 1st runnings. When you have a controlled boil, add your first hop addition. I have found that adding a few drops of Ferm-Cap, along with some stainless nuts helps in preventing boilovers. The nuts create nucleation sites at the bottom of the kettle and release smaller bubbles, not large ones which cause the boilover. Ferm-Cap seems to lay down a thin film across the top which contains the boil. Remember to remove your nuts after you drain your kettle!

Nothing to do now for 45 minutes, so I recommend cleaning out the mash tun. I use my pitcher to scoop, then a paint scraper thingee to get the small stuff out:
My manifold is CPVC held tight with teflon tape, so I disassemble it to clean and dry:
At 15 minutes, I made my 2nd/last hop addition, added Irish Moss and yeast nutrient, and put my immersion chiller in to sterilize. The IC copper will quickly reach 200 degrees, so be careful touching it from here out:
