Last week I shared the progress on the brew stand. This week I kept the momentum going and got the gas plumbing mostly done. The stand looks pretty good and the burners seem to fire with just as much power as a stand alone stand. I have two burners going for now, and the third will get down soon.
When I first conceived of building a brew stand I actually figured I would only employ two burners. As a batch sparge brewer this made perfect sense to me. I normally brewed with two individual stands side by side. However, when found the aquarium stand to start this project with, it just made sense to go to a three burner stand. Hence, the reason I only have two plumbed burners at the moment.
It took a bit of time at the parts department figuring out how I was going to plumb up the burner to the control valve, then the valve to the propane source. I’ll post the full parts list in a separate post for those folks interested in the details. The weakest part of the system is the use of water supply line to soft connect the gas manifold, in black pipe, to the valve and burner assembly. I works just fine. I am just unsure of the heat produced under the stand and worry wether the tubing will be able to take it. Having it melt and burst into flames in my garage is not an experience I am interested in having.
This concern stems from the short height of the stand. Because I cut the legs down to save on material its a little short in profile and the distance from the tubing to the burner is less than 12 inches. A test run to heat some water seemed to not create too much heat, but I am still concerned. I may switch over and hard plumb the line with copper tubing and flare fittings.
A second issue with the short height is that I definitely cannot mount my pump under the burners. The heat is too high and the room is just too tight. I figure I’ll get around that reality by just mounting the pump on a separate portable pump stand off some sort. That way I can easily move the pump around and put the stand away while still having the pump out to clean it. We’ll see how that idea develops after the first couple brew sessions.
That covers it. The next time I post about the stand I hope to be doing it during a brew session with all three burners in action. That leaves one last equipment upgrade, which is to build an HLT for that third burner! But that will be a new video.
