I am looking at this burner:

For a natural gas setup...

Thoughts? Suggestions?

How big a BK and/or HLT are you thinking of using with that monster?

Cheers!

I run NG on my setup and did a lot of research before I settled on a modified BG14. Those jet burners put out a hell of a lot of heat, but they aren't adjustable. They are also notorious for sooting up.

I suggest buying a BG14, drilling out the orifice to 1/8" and adding a ball valve to control the flame. I have 3 on my setup and they work very nicely!

I plan on using keggels..

When you say these jet burners are not adjustable - What do you mean? I was going to add a ball adjust to adjust.

So the BG14 is normally propane? Or whats the reason for drilling out the orfice?

Thanks!!

NG and Propane use different orfice size.

I have burned NG and then converted to propane as I moved from one house to another and had to adapt.

I use converted kegs and am always concerned about the gas build up trapped and lingering below the kettle. The blow back has singed the hair of my knuckles more that once. Be careful when lighting is all I am saying.

IMHO you want to be able to control the gas input as much as possible with both the pressure and the volume of the gas output. You only need that burner to heat the bottom of the kettle and not the outside of it.

The problem with the jet burners is that the way the jets are designed they require a decent amount of gas flowing through them to pull in the proper amount of air (incorrect gas-air mix causes soot). So if you try to turn them down, you'll most likely get a sooty bottom. The workaround to this problem is to cap off a couple of the jets to reduce the output. There's nothing wrong with the jet burners, but IMHO the BG14s give you a lot more flexibility in your design and use.

BG14 burners are designed to run on propane. The pressure of propane is a lot higher than NG, so you have to drill the orifice out to reduce the pressure drop into the burner. The reason these 'banjo' style burners are more adjustable is that there are more jets coming out, and they're much smaller as well. The small flame can just pull the required oxygen from the surrounding air (plus the air intake). The bigger jet burners aren't able to pull the necessary amount of oxygen from the surrounding air,so they have a small venturi setup that pulls air in at the base of the jet.

Hope this helps!

I also Have 3 and helped a friend build a stand with 2. Drilled out to 1/8"
they work awesome. Make sure you make your manifold at least a 1/2''.
Here is the best prices.

This does help! Thanks! SO order these.. drill out the to 1/8 inch to run NG, add a ball valve, and use 1/2 gas (min of) pipe.

Sound like I Got it?

Is it obvious where I need to drill?

Yep, sounds like you got it. The orifice you need to drill out is the brass piece that connects your gas line to the burner. Looks like this-


Here's a pic that shows the hole size difference between high pressure LP (left) and NG/low pressure (right)-


FWIW, 1/8" is kind of an average, and depending on your exact gas pressure you may find that you need a slightly different size orifice for optimal performance. Start small and work your way up, since it's much easier to enlarge the hole than it is to shrink it. I started with a wire size 35 drill bit, and ended up working my way up to a size 29, which is a couple steps larger than 1/8".

Also, depending on where you live the shipped price from agrisupply may not be the best. They have pretty high shipping charges to the west coast, and total shipped price here in AZ was actually cheaper through Amazon.

Awesome - thanks for the help! I'll start small and work up - Thanks for the advice..

Yeah, shipping prices were high, but still cheapest location I could find - already ordered em up!

Last question - Any suggestions on how much room there should be between burner and kettle.. I have not built my stand so now is my chance to make it right

thanks for helping a nube!
