No, I have not.

I believe I'm right around 7.5" WC. A quick read of your previous post tells me that you're trying to increase the fuel to your burners, but you're failing to increase the air - which is the whole point of this thread. Since the NG gas flow pressure is so low, there is not enough gas...

I'm glad you actually tested it as I didn't, but I knew the fan pressure would be less than the gas pressure. I agree with you, and have a hard time seeing where this could create any back pressure into the NG system to create a catastrophic event as has been suggested. It's simply not a...

When you get a chance, stop over at the pottery/kiln forums and the metal/forge forums and let everyone there know how dangerous their home-built forced air burners are. I'm sure they'll appreciate it as much as I do.

LOL, yeah, I knew you were being sarcastic. My points were for the benefit of others.:mug:

dahlseid, Yes - your burners linked are identical to mine and what is generally referred to as BG14's. On 7" WC NG, you will never get the rated BTU output due to the limitations in air flow & combustion.

My air feed only goes into the venturi area about an inch. I understand Hockeyman's concerns, but with such low pressure air and the additional venturi space along with the burner jets, there isn't any way for this to become plugged and force the air back into the gas feed - it's just not going...

No, only air starvation! It's a problem inherent with the design of these burners when used on low pressure fuel (7" WC).

Good luck with that! Please report back your findings as you do your tests.

Whether you need to bore your valves or not depends on if they were originally setup for propane. The orifice on propane is smaller, so you definitely need to bore those out if you are moving to NG. I have installed two of the blower fans on my rig. The original was for my boil kettle, but I...

I wanted to brew in my back yard because I have a nice patio there with natural gas hookup, pool, bbq, etc. However, I also have an ocean breeze that just totally messed with my burners. I now have all my brew gear in the garage and pull the rig out front on brew days. Works good with no...

I have a truck also - I'd never put kegs of PBW in the trunk of my car! :eek:

This is brilliant! Why have I never thought of this? :drunk: I sometimes have a dozen or more dirty kegs sitting around and it takes forever to rotate them through the keg cleaner (bucket/pump). Only downside is I would go through a lot more PBW.

That's cool! I wonder how many pounds they can do at once.

Bump for Dan! You couldn't build this system for even twice the price! This is a great deal for someone wanting to get into an all SS system with a lot of automation features.

Bump for this! I've drank beer from this kegerator and it is a quality build. No expense was spared on the components used to put this together (look at the details in the OP's original link).

Yes, I think so. When I was ready to take the plunge for a nice machine, there was a big difference in features and performance between the $600-800 and the $1600+ machines. At around $1600-$2000, you get machines with dual boilers, plumbed in, shot programmability and commercial quality...

I think several years ago there was a shortage of 53mm accessories, but I don't think it's a problem now. There's a triple basket readily available, naked PF's and plenty of tampers. With Astoria, Wega and a few others doing 53mm, it doesn't seem to be an issue any longer.

What's your concern with the 53mm PF? Having had both 58's and 53's, I can say that I do now prefer the 53's. I feel it is more consistent. It's kind of like the argument for tall/skinny or short/fat mash tuns.

I've been running my LaSpaziale S1 for about 10 years and it still runs like new. I looked at a lot of HX machines, but their idiosyncrasies ended up pushing me to the LaSpaziale. Dual boiler, plumbed in, programmable shot volumes and great temp stability. Not as sexy looking as a fully...
