Lenox Laser also offers flow orifice sizing. #ap511036. This is because LP as a vaporized gas has a much smaller mass than NG and this means the LP orifice will have a much smaller hole than the same BTU’s for NG which needs a much larger hole in the orifice. If the propane load in standard cubic feet per hour (SCFH) is desired, divide the BTU/HR load by 2488 to get SCFH. I have tried calling their 800 #, but have been put on hold twise for over an hour. $15.75 /Each. They cannot be used for pipe size of less than 35 mm diameter. #hpm858.
