PENALTY.
BE IT ORDAINED BY THE CITY OF BEAUMONT, TEXAS:
1.
That Section 28-202 of the Code of Ordinances of Beaumont,
Texas, be and the same is hereby amended to read as follows:
"Section 28-202. Required size of piping and outlets.
(a) Minimum size of certain piping and outlets.
(1) All consumer's gas piping from the point of delivery
to the house piping shall not be less than one
inch in diameter.
(2) Outlets for gas ranges shall be not less than three- ✓
fourths (3/411) inch pipe.
(3) The minimum size of outlets shall be one-half (1/2")
inch pipe.
(4) In no case shall a branch line to any gas appliance
be installed having a diameter smaller than the inlet
connection of the appliance.
(5) In no case shall an extension to gas piping be
installed from pipe of smaller size than the extension.
(b) Required gas sup ley. The. hourly volume of gas required
at each out eza l be taken -as not less than the maximum hourly
rating, as specified by the manufacturer of the appliance to be
connected to each such outlet. To obtain the cubic feet per hour
of gas required, divide the maximum BTU input of an appliance by
the average BTU heating value per cubic foot of gas. Always
divide by 1000 unless the actual average BTU value is lower. Where
the BTU rating of the gas appliances to be installed has not been
definitely specified, the follovdn.g table may be used as a reference
in sizing pipe to estimate the approximate requirements in BTU
per hour of typical appliances:
APPROXIMATE MAXIMUM DEMAND OF TYPICAL GAS APPLIANCES IN BTU PER HOUR

Restaurant range - 4 top burners, two ovens 150,000
Restaurant range - 6 top burners, 2-4 ovens 2403000
(c) Required gas house piping size. To determine the sizes
of consumer's gasouFi se piping proceed as.follows:
(1) Measure the length of pipe from the point where the
house piping begins to the most remote outlet in the
building.
(2) In the first horizontal line in Plate 12, select the
vertical -column showing that distance, or next longer
distance.if the plate does not give the exact length.
(3) Use this vertical column to locate all gas demand figures
for this particular system of gas piping.
(4) Starting at the most remote outlet; find in the vertical
column just selected, the gas demand for the outlet. If
the exact figure of demand is not shown choose the next
larger figure below in the same column.
(5) Opposite .this demand.figure in the first column at the
left in Plate 12 will be found the correct size of pipe.
(6): For each succeeding section of pipe, determine the total
gas demand supplied by such section and then proceed,
in the manner outlined above to determined the..size of
each section of pipe.
(d) Required gas yard line size. To determine the size of
consumer`s gas piping trom the point of delivery,to the house
piping, proceed as follows:
(1) Measure the length of pipe from the point of delivery
to the point where the house piping begins.
(2) In Plate 12 select the vertical column showing that dis-
tance, or the next longer distance if the table does not
give the exact length.
(3) In this vertical column, select the figure corresponding
to the demand figure.of.the house piping. If the exact
figure is not,shown, choose the next larger figure below
in the same column.
(4) Opposite this demand figure'on the same line will be
found the minimum size of pipe allowable.
(e) Pipe sizing requirement for special conditions. For
conditions other than those set torth in subsections (c.and (d).
above or those covered by Plate 12, such as longer runs or larger
sizes of piping, greater gas demands, application of a diversity
factor when piping multiple -family dwellings, pressures higher
than .15 inches or lower than 4 inches of water column pressure,
or specific gravity other than 0.55 to 0.75,.the size of piping
--
required shall be calculated in a manner satisfactory to both
the plumbing inspector and the.gas company. Where pipe sizes
larger than those set forth in this section are specified by
pipe sizing requirements established by the .plumbing inspector
or by the gas company, these large sizes shall be used.
(f) Outside use of tubing regardless of any -...installation
or sizing requirements in this or any other section, smaller
pipe, or tubing of adequate size installed entirely outside
building may be used to connect appliances located outside
building.
