I am looking to build a natural gas line in the back of the house for an outdoor grill. There is a line already running to the rear of the house for a gas fireplace, as depicted in the picture.
The plan is to direct gas to a grill with 61000 BTU and a burner with 30000 BTU - there may be times when both are used simultaneously - unlikely that I'll be running the fireplace at the same as these 2 cooking appliances. The existing run is about 50 ft. from the main line - and the outdoor grill will likely extend/divert/add another 10 ft.
My questions are:
- Can I use a CSST pipe to tap into one of the 2 available capped ports with a provision for a shutoff valve?
- Can I run the pipe under a deck, or will it have to be buried?
Of course, a licensed professional will handle the installation and pressure test, but before seeking quotes, I wanted to understand the scope of work. CSST pipes appear to be moldable and easier to run compared to metal pipes - at least to me :)
