American Standards Association Manual — Copies in City Clerk's Office. The installation of gas piping and tubing for pressures not to exceed three (3) pounds per square inch gauge pressure and the installation, alteration, maintenance and use of gas appliances and accessories connected thereto which comply with the standards set forth by the American Standards Association in their manual entitled "Installation of Gas Piping and Gas Appliances in Buildings," 1964 Edition A.S.A. Z21.30 - 1964 (or subsequently revised editions), as supplemented and modified by this Section, shall be considered prima facie as conforming to reasonable standards of safety. The provisions of said A.S.A. Z21.30 - 1964 (or subsequently revised editions) are incorporated herein by reference thereto as though set out in full.

[Ord. No. 530 §3, 8-15-1966]
A. 
When applying two (2) pounds per square inch pressure at the meter, piping systems shall be designed to allow a maximum of one and one-half (1½) pounds per square inch pressure drop between the meter and the regulator that reduces pressure to six (6) inches water column for appliance use and will be designed to allow up to one (1) inch water column pressure drop between the regulator that reduces pressure to six (6) inches water column and the installed gas appliance.
B. 
When supplying more than two (2) pounds per square inch pressure at the meter, the pressure drop shall be such that the minimum inlet pressure to the regulator that reduces to six (6) inches water column for appliance use shall not be less than fourteen (14) inches water column pressure.
C. 
The size of gas tubing hereafter installed shall conform to the following Table:

[Ord. No. 530 §4, 8-15-1966]
A. 
Regulators installed to reduce pressure from a maximum of three (3) pounds per square inch pressure to six (6) inches water column for appliance use shall:
1. 
Be rated for at least three (3) pounds per square inch gauge operating pressure.
2. 
Have full shut off to maintain reduced pressure under static load conditions (no gas flowing).
3. 
Be rated to supply the load of appliances it feeds.
4. 
Be vented by either a number eighty (80) vent limiting orifice or by a ball check type regulator vent limiter.
5. 
Be installed in accordance with manufacturers instructions.
6. 
Be installed on piping where it is not concealed.
[Ord. No. 530 §5, 8-15-1966]
All appliances rated for inches water column pressure operation must have an appliance regulator reducing pressure from six (6) inches water column to the rated operating pressure.
[Ord. No. 530 §§6-7, 8-15-1966]
A. 
Piping carrying pressure in excess of fourteen (14) inches water column shall be clearly marked with the pressure the pipe is carrying at as close to six (6) foot intervals as possible.
B. 
All domestic piping carrying gas at pressures above fourteen (14) inches water column shall be semi-rigid copper tubing.
[Ord. No. 530 §8, 8-15-1966]
When copper tubing runs in a wall, flexible metal conduit shall be used where the tubing runs through the plate-spaces. In the wall, the conduit must extend at least eighteen (18) inches either side of the plate-space.
