Broilmaster P3 Natural gas grill burner flame adjustment

[Cropduster172]

Have a Broilmaster P3 grill natural gas grill and I recently replaced the manifold and valves assembly, the burner and new ceramic briquettes.
The burner comes with the Venturi tube openings adjustment set to 50%.
I'm just not sure if this is how the flame should look after 5 minutes or so.
Anyone have any experience here? Thanks

I would think you might want it to be blue all around like it is in the middle.

I would believe you want to back off the adjustment from where the flame starts to dance and lift off the burner.

You want to adjust the venturi openings to eliminate, or at least minimize, the orange flame at the edges. If my memory serves me correctly, orange flame means too much air through the venturi.

OK. Spent some time getting this thing right...in 93 degree heat on the deck at 0930hrs.
I opened the Venturi screens and additional 25%, reamed a plastic barbed dental pick through the orifices and blew them out with canned air.
Reassembled and tightened everything. It's definitely burning hotter and better.
So its more air for less orange flame and less air if the flames are floating above the burner.

ON propane, I have experienced a low orange flame due to the overfill prevention kicking in thinking there is a gas leak. Sometime it is hard to get it back to normal. I would shut off the propane at the tank valve, disconnect the tank from the regulator, make sure burners are OFF, then reconnect the tank and S-L-OW-L-Y open the valve a bit then set one grill vale to MED and light it. then slowly open it to HI.

HTH.
