The following specifications and requirements shall be observed
in order to secure gas. The city gas inspector shall observe and be
directed by same before issuing a certificate. The size of the pipe
shall not be less than called for in the following tables.
(1) All
piping shall be new galvanized pipe and galvanized beaded fittings.
No cast iron fittings under three inches shall be allowed.
(2) No
gasfitter shall install gas piping in any new or old building within
the city limits without first making application and receiving a permit
from the city gas inspector for the construction of said work. These
permits shall be made in triplicate: one for the city, one for the
gas company and one for the party doing the work.
(3) Any
contracting gasfitter shall pay to the city a fee as set forth in
the fee schedule in appendix A of this code as an occupation fee.
(4) In
piping houses, the gas company, with the assistance of the city gas
inspector, will decide where the meter shall be located, and the fitter
shall extend the inlet riser to terminate within all six (6) inches
of the proposed location of the meter and to the right of the same.
(5) The
gas company will make all necessary connections with the street main,
run pipe to the regulator from the main and set the regulator, and
if necessary a curb box free of expense to the consumer, but same
shall remain the property of the gas company. The line from the regulator
to the meter is defined as the yard service line, and shall not be
run in the same ditch with water or sewer lines.
(6) To
accommodate different tenants, the gas company will set as many meters
as there are separate consumers in a given building, connecting the
meters to one service pipe, provided the service pipe is large enough
to provide ample supply, provided further that expenses of this yard
service line, or meter loops, and piping from meter to appliance shall
be done at the expense of the property owner.
(7) Elbows
and not knees shall be used on all meter inlet connections. All connections
or disconnections of meters for any purpose will be made by employees
of the gas company only.
(8) Cement
shall not be used or caulking done to repair faulty fittings, pipe
or work, and all imperfect fittings and pipe must be replaced.
(9) In
no case shall valves or unions be placed between ceiling and floor
or in an inaccessible place, so that the stuffing box or valve cannot
be repacked or union gasket replacement [replaced]. Unions shall only
be used at water heaters and cook stoves.
(10) Air mixers must not be placed in airtight ash boxes; they must be
out where free flow of air can reach them at all times. Adjustable
mixers must be used.
(11) The burr left on the inside of gas pipes must in every case be reamed
out.
(12) All outlets or risers where fixtures are not placed must be left
securely capped.
(13) All drops and openings for lights must project at least one inch
beyond a plaster wall or ceiling and must be securely fastened to
a joist or studding or to notched or cross pieces fastened to a joist
or upright studding.
(14) No more than one elbow shall be allowed between burner and mixer.
(15) Where pipe runs through a stone or brick wall the opening around
the pipe must be cemented.
(16) No tees will be allowed in the service line between the curb and
the meter.
(17) No service line will be passed with size less than the size of pipe
from meter to first fire.
(18) No house line will be passed with less than one (1) inch pipe to
the first fire. Not more than eighty (80) feet of one (1) inch piping
will be allowed in either the house piping or yard line.
(19) No lines will be passed for fires smaller than three-quarters (3/4)
of an inch. Not more than fifty (50) feet of three-quarters (3/4)
inch line will be allowed in housing piping.
(20) Gasfitters must place heavy brass stopcocks on the end of every service
line at the meter location.
(A) No unions or tees will be allowed between meter and regulator except
that a union must be provided in the regulator riser. In cases where
the yard is terraced, an offset bend will be made in the service line
rather than putting in fittings.
(B) No service will be allowed to run under houses between the regulator
and the meter location.
(21) No pushing will be passed on any pipe whatever is necessary to reduce
size, use reducer [sic].
(22) The requiring of vent pipes on appliances is to be left to the discretion
of the gas inspector.
(23) Under these rules the gas company shall not set a meter until the
work is satisfactory to the gas inspector. For determining the minimum
size or service at house lines the number of openings shall not be
considered to be less than the total number of rooms in the building
minus two.
(24) The word “opening” signifies the point in the piping
where a branch line extends to any single outlet from the main reed
line.
(25) The following specifications for house piping must be strictly adhered
to:

(26) For more than 12 openings, or for furnace care, pressing establishments,
or hotel service, consult gas company for specifications.
(27) When the gasfitter has completed the system of house piping and the
yard line, and has all full drop and bracket extensions firmly and
permanently fastened, he shall test the piping and, if found to be
tight, file a written application for test with the city gas inspector.
If the pipes are found to be tight and the size in accordance with
the city ordinance, then the city gas inspector shall approve same
and issue a certificate therefor, the sum set forth in the fee schedule
in appendix A of this code to be paid by the said fitter completing
said work, within twenty-four (24) hours after said test. During the
inspection, the fitter, or his representative, may be present. If
pipes, fittings, and work do not pass inspection, and it becomes necessary
for the inspector to make additional test, he shall be paid by the
fitter the sum set forth in the fee schedule in appendix A of this
code for each such additional inspection.
(28) The piping must be tight under a pressure of fifteen (15) pounds
on a mercury column gauge for fifteen (15) minutes. This test shall
be made after floors are laid, but before fixtures are connected,
and in case of a yard line before the ditch is backfilled.
(29) Any additional pipeline or outlet put on after the certificate is
granted must be reported to the inspector for inspection and test.
(30) In all cases where gas pipes touch or are in such position that there
is likelihood of their being touched by an electric wire the pipe
must be insulated at such point.
(1984 Code, sec. 6.41)
The provisions of this division shall not apply to the gas piping
in houses or buildings which are in use at the time this division
takes effect, if said piping in such houses or buildings is satisfactory
to the gas inspector, and if upon test found free from leaks and of
sufficient strength to withstand the pressure provided herein; provided,
however, that if such piping be altered, changed or additions made
thereto, then the terms of this division shall apply to all piping,
and to said changes or alterations, in all its terms.
(1984 Code, sec. 6.42)
In cases where gas is being furnished to a consumer whose service
lines or yard lines are leaking or are otherwise defective, the gas
company is hereby authorized to discontinue service immediately, if
repairs are not promptly made to the defective piping.
(1984 Code, sec. 6.43)
The gas company will not be allowed to connect a meter on any
job until the certificate of inspection is on file in their office.
Oral clearance will not be considered as a release.
(1984 Code, sec. 6.44)
Hereafter, the use of black pipe is permitted in addition to
the galvanized pipe for the piping of residences and/or business property
in the city where such black pipe is not to be buried in the ground
or does not rest upon the ground or soil.
(1984 Code, sec. 6.45)
