ThreeDJ16 Posted September 23, 2006 Report Share Posted September 23, 2006 Well, I wanted to have more time to write an appropriate post for the subject, but that has not come to fruition yet (maybe soon). But short story is as follows: I cannot find anything on the Internet that says there is a difference in standard size pipe verses metric - there are equivalencies for the common sizes as they are internationally standardized. I will post some web links below, but it looks like we should have no safety issues using our fittings with these burners. And from Tony's investigating, he has determined that 1/8 pipe seems to be the appropriate replacement size on the existing gas valve. I am hoping to talk someone into giving me a pretty close measurement on the larger thread where it goes into the burner?? http://www.wsdot.wa.gov/reference/metri ... s.htm#Pipe http://mdmetric.com/tech/tic1e.htm#cht8 I also thought I would re-post this nice gas orifice chart again for those who might need it for natural gas conversion: Low Pressure Chart: http://www.joppaglass.com/burner/lowp_chrt.html High Pressure Chart: http://www.joppaglass.com/burner/highp_chart.html Quote Link to comment Share on other sites More sharing options...
ThreeDJ16 Posted September 23, 2006 Author Report Share Posted September 23, 2006 Burner BTU Info?? Hey Dennis, do you have any BTU info on that burner? If we had an approximate BTU range for the burner, we could use the chart on the previous post to get an orifice drill size for anyone wishing to change to natural gas. -=Jasen=- Quote Link to comment Share on other sites More sharing options...
ThreeDJ16 Posted September 23, 2006 Author Report Share Posted September 23, 2006 I would also like to mention that Dennis is using a 3/8" flare fitting now, which is a very commonly used gas fitting in the US. This fitting will allow a much easier install by picking up a regulator & hose combo from lowes (you can usually find 3/8" flare or 3/8" pipe thread - get the flare). -=Jasen=- Quote Link to comment Share on other sites More sharing options...
gerard Posted September 23, 2006 Report Share Posted September 23, 2006 I guess no one else is childish enough to comment but: Does it bother anyone else that Dennis, TC, and D_J are teaming up for orifice research? Quote Link to comment Share on other sites More sharing options...
ThreeDJ16 Posted September 23, 2006 Author Report Share Posted September 23, 2006 Damnit, you posted before I had a chance to lock this topic. It was to be an info only thread; oh well! -=Jasen=- Well, I take it back. I guess I should leave it open so folks with real questions can post to it.

So Cal Cooker Posted January 15, 2007 Report Share Posted January 15, 2007 BTU Rating I need to convert the burner for my OTB to natural gas. So I would be interested in the BTU rating of the burner so I can make the appropriate adjustments in hold size. Does one only need to change the entry orifice size or actually drill out the burner holes? Any help would be appreciated. Chuck Quote Link to comment Share on other sites More sharing options...

There are a couple of threads here of folks whom did just that. I will locate one and post it here when I find it. But from what I recall, Dennis said the burner is about 20K. Just remember, you can always drill out larger if it does not work, but it is a lot harder to fix if you drill it out too much. -=Jasen=- Quote Link to comment Share on other sites More sharing options...

If I remember correct you had a gorgeous covered outdoor cooking setup. Gives me something to dream for anyway. -=Jasen=- Quote Link to comment Share on other sites More sharing options...

DennisLinkletter Posted July 27, 2011 Report Share Posted July 27, 2011 Re: Pipe Size Info & Orifice Chart (for NG conversion) I need to convert the burner for my OTB to natural gas. So I would be interested in the BTU rating of the burner so I can make the appropriate adjustments in hole size. Does one only need to change the entry orifice size or actually drill out the burner holes? Your burner came with two jets.. the one installed is for the LPG and the one included for natural gas. Just swap them out. The jets are small brass plugs drilled out. I can have the factory look up the hole size if you have lost them. If you unscrew the brass fitting from the cast iron burner you will expose the small jet. Only that needs to be changed. Quote Link to comment Share on other sites More sharing options...
mguerra Posted July 27, 2011 Report Share Posted July 27, 2011 Re: Pipe Size Info & Orifice Chart (for NG conversion) Great service there. Including both jets. No need for the customer to have to rig a solution. I daresay there are a LOT of customers who have no idea what a jet is, how to modify one, or rig one from scratch. Nor should they be expected to. Good job Dennis. Quote Link to comment Share on other sites More sharing options...
