Figure 6: Typical Gas Piping
1. INSTALLATION OF NATURAL GAS PIPING
The installation of the gas piping and the following test procedures must be
performed by a qualified installer or service person.
The following chart may be used as a guide in sizing natural gas supply piping.
The input loading of all gas appliances installed on any main or trunk line must
be totaled to determine its required carrying capacity.
EXAMPLE: A line must supply a furnace of 100,000 BTU/hr input, a hot water
heater of 40,000 BTU/hr input and gas range with a 30,000 BTU/hr input
capacity. The total BTU/hr input loading on the line is 170,000 BTU/hr. The
200,000 BTU/hr column on the chart must be used in sizing the pipe.
