The size of the gas supply lines must comply with local codes and
recommendations of the local gas company. United States: Refer
to National Fuel Gas Code, ANSI Z223.1 - latest revision, (same as
NFPA Bulletin 54). Canada: Refer to Can 1-B149.1 and B149.2:
Installation Codes for Gas Burning Appliances.
A 1/8” NPT plugged tap must be installed in the gas line connection
immediately upstream of the burner that is farthest from the gas
supply meter. The tap is required for checking system gas
pressure.

Lines
Meter and service must be large enough to handle all the heaters
being installed plus any other connected load. The gas line which
feeds the system must be large enough to supply the required gas
with a maximum pressure drop of 1/2" w.c. When gas piping is not
included in the layout drawing, the local gas supplier will usually
help in planning the gas piping.
