Default Burner Question - KAB4

I've got a KAB4 fairly new, but I'm not real impressed with its performance. It takes me 30min to bring my 5 gal batch full runnings (8 gal) to boil (starting at 160F).
I was suspecting the height of the burner and saw a thread here that lists the std height at 4" which is where mine is (see photo from thread below).

So I put that idea aside, until I saw this pic of the same burner on Amazon:

In the amazon photo the pot supports look to be about 3" lower.

The flame on the burner is nice and blue and has good flow and air intake (ie no yellow or orange). So now I'm back to the height.

Anyone have any tips for adjusting the height on one of these?

Longer bolts and shims under the burner.

Are you sure that you have the damper adjusted correctly. Meaning are you getting all blue flames.

Also, with the 30 PSI regulator it sucks ALOT of propane. Make sure you tank is full and set it in a warm water bath. That greatly improved my performance on a cold day.

I've used it 3 times. Some on cold days (30F some not so cold 50F). All the flames are blue, none of the holes are plugged.
I've adjusted the gas and intake by turing up the gas and adjusting the intake until I'm at max gas flow with all blue flame.

The flag went up with the difference between the amazon pic and what I have...

How?
The pot supports are welded to the cast iron ring/guard. I guess i'llhave to cut a deeper notch and new blot holes to muve it up or cut and re-bend the existing bars (how i have no idea).

Wow - I am curious myself. Look at those two pictures, they are completely different stands!

Mine is 2" from the top of the burner to the top of the stand. That has to be your problem, because mine is a heating monster! But it doesn't really have a high flame, I would do whatever take to get that burner up to proper height.

Where did you get that? I've never seen a stand that high for that burner.

I really dont think he'll be able to - that one from Amazon has the wind guard go all the way up to the supports - the one he has, has that extra piece running from the supports down to the windguard (giving it the extra space). That really sucks as I was looking to upgrade a burner with the KAB4 - but I would want to ensure that I was getting the "Amazon" style.

Mine just came and its the same as GreenwoodRovers



I am just going to cut the supports and weld some new ones on so I can use it with better stability with the keggle

Oh yeah that burner is not mounted from the bottom like most are.
The only way you will be able to move it up is to weld or bolt some tabs to the ring and then bolt the burner to those tabs. You will lose the wind gaurd doing this.
So the other way would be to weld another wind gaurd above the one you have and bolt the burner to that. Or you could cut the stand and reweld it to where you need it.
