The burner and kettle will work. It is an 8 gal max vol, that's 4.5-5 gal batches, but you need to look at building up to a mash cooler or get a keg block party together and cut for a keggle.
If you're going higher than 1.060ish you will take a hit on volume. Which, I have not had an issue with. There is always the partial mashing for those brews. I have to say, it will make beer, but eventually you will want the upgrade to a better kettle.
