The transformer receives 110V in and outputs 24V to a terminating block (bottom of picture). I then come off of that block into each of the PIDs (via a switch). -- Josh

The ball valves are fine. The areas that emit the most heat are the corners where the openings are. If I was to redo my keggles, I'd forgo the analog thermometers and put the siteglasses 90 degrees to the valves. They were mainly added as a backup in case a PID dies mid-brew, but I'd use my...

I haven't had any problems like that. I set them up there at the beginning of a brew day, and I don't move them until it's time to clean. -- Josh

The outside dimensions are 20" (deep) x 60" (long) x 30" (high). Everything else should be decipherable from those numbers. The top and bottom structures are identical, connected by four corner posts. Have fun with your build! This thing is a joy to brew on! -- Josh

Thanks John! There's no reason you couldn't go with Love controllers. I actually like Love controllers a lot, and used them on my Keezer and Fermentation Kabinett. For this project though, I liked the Auber PIDs because they show you the current and target temperature at the same time and the...

Ah yes, that helps. Then I think you want this: 24V ------> Switch (Auto) ---> Red Light ---> PID ---\ \---> Switch (Hand) ---> Yellow Light ---------------> To Valve It's still a SPDT switch and the lights are rated for 24V. -- Josh

I'm guessing you want the indicator lights to show that the burner is being sent a voltage? If so, just buy 24V lights and put them on the downstream side of the PID. So, if you had: 24V ------> Switch (Auto) ---> PID ---\ \---> Switch (Hand) ---------------> To Valve It...

To connect a rigid gas pipe directly to the BG14 orifice, you need the flared end to be female. -- Josh

Right, the switches for the pumps and the main are single pole single throw, and the HOA switches for the burners are single pole double throw. The "oh shnit" valves are the 3 valves coming out of the gas beam manifold; one for each burner. Turning one of these off prevents gas from flowing...

If you're talking about just grill-style, push-button spark ignitors, then yes. If you are talking about something like a Honeywell S87B1008, then you will need to use different valves. Mainly the cost goes up considerably to put together the "ignition-sequence module" style. -- Josh

The HOA switches just add the ability to override the PID controller. So for example, if you want to fire the burner to boil some water you can just hit "on". The "off" position is pretty obvious, but there are times when you want to turn off the burner now and not mess with the PID. By the way...

The AHA posted a writeup about my system. Check it out here. :mug: -- Josh

Barrier Island Brewing (located on a barrier island)

Mine is an upright freezer from craigslist that I added a Love controller to: I keep various ingredients and yeast in the door shelves: It can hold four 6.5 gallon carboys, six 5 gallon carboys, or some other mixed combinations: If I ever take the door shelves out and...

Keep in mind that most high pressure burners can be easily converted to low pressure propane (or even natural gas), by replacing or simply drilling out the orifice. The gas valves I used are for low pressure only. -- Josh

It's just welded the ends shut as a single tube. I notched out the ends of the pipe just like I did here: I then bent the flap of metal over the end nice and tight, and welded it shut. Post #6 here gets into the gas manifold pictures. In the last picture you can see the end welded shut...

Thanks. Good luck with your build! -- Josh

That transformer should be fine. I got the bridges and switches at Radio Shack. The power in/out modules I got from some local electronics shop, but you can find those online. The RTD panel connectors I got from Auber and for the 24V out connectors I used little DC connectors from Radio Shack...

A friend of mine gave it to me. Sorry, I'm not sure where you might find one like that. -- Josh
