23 Tip Jet Burner problems
 
OK, now I have a new problem.
I am finishing the build of a brutus 10 stand. I am using (3) 23 tip jet type burners from Top Food service, that I have plugged to only use 10 tips.
System is configured for L.P propane, low pressure regulator on the propane tank.

I tried to fire up one of the burners the other day, and I could only get one of the 10 jets to light on the burner.

I tried a high pressure regulator and all the jets fired, blue flame at bottom, tipped with yellow, about 3 - 4 inches high. However, the gas vlaves that I have from honeywell, I have been told can be damaged by high pressure.

So I re-connect the low pressure regulator to the propane tank, and it goes back to not wanting to light all the tips.

Things I have done to try to correct problem.
1) Checked for leaks, none located.
2) Swapped regulator with ANOTHER new LP regulator, same problem,
3) Called place where I got the burners, they ASSURED me, after they checked, that I did indeed have the proper LP burners, and not a NG burner.


At this point, I am lost, and need help trying to figure out what the problem is. ANY help would be greatly appreciated.
Thanks
Josh

I don't have any advice but I just want to say that I sympathize with the fact that you're finding out first hand how fickle these burners can be.

I use the same burner for my 50 gl mash tun with the Honewell gas valve, no problem.

Did you install the LP kit for your Honeywell valve?
The first thing I had to do adjust the pressure, remove the cap and set the
correct pressure for your burner.

Thanks Bobby, I know you had issues with yours as well.

Yes I sure Did.

The thing is, when I was test firing the burner, I was just using the boil kettle, bypassing the gas regulators and I shut off the gas valves to those 2 burners. So essentially I was running straight gas to the boil burner.

Just to add something else, I did seal around all the jets on the burners.
Seems, my edit to your post didnt look like I thought it would, Sorry.

My set-up uses four burners.
To prevent the low pressure valves, and burners from not getting anough gas flow, each valve is equipped with a low pressure regulator.
The tank supplies the gas at high pressure to all regulators.

Sample of the different quick exchange gas modules I use.
All my burners required adjusting the valve outlet pressure.

Yup - fickle. I've got the same burners and similar issues. I kind of accepted some of the limitations and resigned myself to installing a more comprehensive fix "later" (read: likely never). At this point, I am comfortable with my diagnosis that the ignition issues are from pluging jets and having less jet flame crossing over unignited gas than the burner was designed for.

My fix is that I just don't try and light the burners unless I have the kettle/MLT/HLT sitting on top of the burner to capture gas. In open air, it can be difficult to get them all going. Other than that, I adjust the pilot flame to throw a pretty big spread when I first light the burner. After a few minutes, it seems to sort itself out.

I am lucky, have never seen a pluged jet.

Since my system is automated the burners have to fire.

I was just thinking,
since I am using an integrated gas beam, would I have to purge out the "air" in the beam for the jets to work properly? Could there be some residual air left in there, even after running the bk burner with the high pressure regulator?

This all a very easy fix, I should have posted this solution a while back, people plugging up burners , switching from high pressure to low pressure etc.

Please do yourself a favor and get an 0-30 psi or a 0-60 psi pressure regulator, they work the bomb on these jet type burners and probably well on all others . Get the right flame every time..
