For propane, I used 3/32". I'm quite happy with the results.
Use this chart for reference.

You can do that, but Blichmann does make an orifice specifically for NG. I have used one of them and it works well.

Sorry I should have been more clear, I am converting to low pressure propane. So does the 3/32 not sound like a good idea?

That's my fault - I missed it. Yeah, drill it out then

This may end up being a direction I go... I have the BG-14 High Pressure Burners as well. When changing to low pressure LP is the Orifice the only change made to the burners or does each and every port on the burner face need to be drilled out too?

Secondly, does the low pressure LP only save in fuel consumption or are there other benefits to the change over?

Thanks,

Mark

The orifice size is the only change you need to make to the burner.

Truly, the only reason I went low pressure was so I could use the Honeywell automated valving.

As a side benefit, it is nice and quiet. My first burner was the Bayou Classic SP-10 that sounded like a jet engine.
I can't even hear the low pressure burners over the noise my pumps make.

Onehoppyguy, looks like you deal alot w/ low pressure on these banjo burners which should be identical to my blichmanns. So is the size you mentioned the best for fuel, heating or combo. Just looking for a little info. Also can I pick that bit up most places or is it hard to get. Thanks again for the help

I ordered the valves for the Hurricane burners from Williams brewing, they work extremely well on the burners with my standard natural gas pressure. The size on those valves was .1250
