I have used this forum and other information sources to research the required size of a gas line extension for an outdoor BBQ. I have attached a diagram showing the existing natural gas appliances and facilities at my home located in Chester County, PA - a suburb of Philadelphia.
Using Table 402.4(2) for Metallic Pipe of the 2012 International Fuel Gas Code and 125' as the maximum length for the run, an extension utilizing 1/2" pipe appears to sufficiently service the new grill, but just barely.
Since hard pipe is my least attractive option considering routing under an overhand and a deck, I would prefer to use CSST or PVC coated copper tubing such as Gas-Tec/GasShield. According to IFGC tables 402.4(9) for Semirigid Tubing and 402.4(15) for CSST, 1/2" copper or ED18 CSST tubing is insufficient for the grill extension. A minimum 3/4" tubing or ED25 CSST appears to be required. (I get the same result if I substitute 100' as the maximum run length.)
Thank you.

- Based upon the above, have I correctly calculated the sizing requirements for the line extension to the grill?
- Am I correct in not considering the backup generator in my calculations because it is fed directly from the meter?
- Please provide corrections, thoughts and suggestions on how best to handle this project.
Thank you.
