Refer to Table 1
for information relating to the sizing of gas supply piping. These charts are
based on the general flow characteristics of commercially produced black carbon steel pipe. If
in doubt regarding flow capabilities of a chosen line size, the next largest size is recommended.
Refer to Figure 3
for the typical gas piping schematic to meet U.L. requirements in the NVC
burner firing ranges.
