Off topic: Weber grill

Hi all, wasn’t sure where to post this. I want to convert an older Weber grill from NG to LP. It’s rated at 38,000btu/hr with three burners. I already cleaned the NG orifices and soldered them closed. I’d assume I need to divide the 38,000 by three and then drill out the orifices to handle 12,666btu/hr each? If so, what number drill bit would that be???

    Thanks Zman, so kindly correct me if I’m wrong, drilled them out using a #58 bit and the burner flames seem very high. What am I missing???

    What pressure are you running?

    Honestly not sure what the pressure is, the grill is now hooked up to a standard 20# tank with regulator and hose from a different LP grill

    If your pressure is the same as the chart (11" WC) it should all work.Most LP bottle regulators are preset to 11" but it might be worth checking. I have seen "cajun burners" that run at higher pressures.

    Look at the regulator body. Typically has the pressures stamped on it.

    Did you consider the doohickey that mixes air with propane so that you can stay with NG jets?
