I suggest you batch sparge for your first few brews, until you are used to your systems and processes.
I still batch sparge after 50 batches, and this is my routine:
1. I heat my mash water to about 8ºC higher than my target temperature. So if I want to mash at 66ºC, I heat my HLT to 74ºC.
2. I preheat my mashtun with 1 kitchen type kettle of boiling water, and drain that off just before mash in.
3. I run about 4 to 5 litres of water from my HLT into my mashtun, and dump in about half my milled grains, and stir for about 30 seconds or so.
4. I then run about 4 to 5 litres more water from the HLT and dump in the balance of the grain. I stir for about a minute to mix it properly and break down any dough balls. I measure the temperature of the mash, and add more water bit by bit until I reach my mash temperature.
5. I cover the mash with a fitted piece of yoga mat to isolate the headspace in my mashtun.
6. Refill your HLT and heat to somewhere between 90ºC to boiling, turn off the heat, and just leave it until you are ready to sparge.
7. At the end of my mash (60 to 90 minutes depending on what I'm brewing, but 60 is fine for your first one) I add about 5 to 6 litres for a mash out and stir. You can choose not to bother adding this if you don't wish to.
8. I vorlauf about 4 or 5 litres, and then start my drain into my kettle. Don't be tempted to run it off too fast. A slower run-off will ensure you don't get a stuck mash or sparge.
9. Once the run-off is complete, check how much you've collected into your kettle (I use a graduated copper tube I have marked in 1 litre increments).
10. Let's say I want to collect 32 litres, and I have 16 litres in my kettle. I then know I need a further 16 litres, so this is what I add to the mash as my sparge.
11. Stir it for about 30 seconds, and repeat the vorlauf and then sparge into the kettle.
12. For my system I need to collect about 32 litres to allow for evaporation and trub loss, to ensure I get 23 litres into the fermenter.
13. Bring your kettle to the boil, add hops at the appropriate times, chill the wort at the end of your boil, drain to the fermenter, aerate, add yeast, and ferment.
It really is quite easy. Good luck, TL's SNPA recipe is a good one. It was my first AG, and I've done a couple more since then.
Keep notes of what you do including temperatures, time frames, volumes etc so you can fine tune your system and routine for your next brew.
