All gas piping equipment and appliances for

Ch. Comm 40, Wis. Adm. Code,[1] while not exclusive, shall be deemed to be generally accepted
good practice.

Editor's Note: See now Chapter SPS 340.
A.Â
All gas-consuming appliances installed shall be equipped
with an effective draft diverter, shall be properly vented to a suitable
flue, and shall be inspected to determine that no products of combustion
escape into any room, except that gas refrigerators, gas mangles,
gas laundry dryers, domestic gas ranges bearing approval of the American
Gas Association (AGA) and other appliances, the total consumption
of which is less than 5,000 Btu per hour, need not have draft diverters
or be vented to flues.
B.Â
Piping shall be of a size and so installed as to provide
a supply of gas sufficient to meet the maximum demand of all appliances
served by that piping without undue loss of pressure between the meter
and appliance or appliances. The AGA table shall apply where pertinent.
C.Â
All piping, equipment and appliances shall be tested
for tightness before being used, either by a meter turn-on test or
an air-pressure test as follows:
(1)Â
Meter turn-on test. All gas outlets shall be closed
and gas shall be turned into the system and the hand on the test dial
of the meter carefully watched to ascertain that no gas is passing
through the meters. This test shall be applied for a reasonable length
of time, but in no case for less than 15 minutes.
(2)Â
Air-pressure test. Air pressure of not less than three
pounds per square inch above the atmospheric pressure shall be applied
to the system for a period of not less than 10 minutes. In case of
concealed piping, the air pressure test must be used, with pressure
at not less than six pounds per square inch above atmospheric pressure.
(3)Â
Standard full weight wrought iron or steel pipe, free
from defects, shall be used in conveying gas from meter to appliances,
except that approved seamless, well-annealed, nonferrous tubing with
approved fittings may be used for permanent connections of small stationary
appliances such as radiant fires installed in fireplaces, etc. All
fittings for wrought iron or steel pipe, except stop cocks or valves,
shall be of best quality malleable iron. Threads shall be in accordance
with the American Pipe Thread Standard.
