<br />ing and shall be located ahead of any tubing
<br />serving as an appliance connection. Appli-
<br />ances, such as central heating, room heaters,
<br />unit heaters, and water heaters, shall be con-
<br />nected to the house lines with rigid pipe.
<br />Other flue connected appliances, such as gas
<br />incinerators, recessed wall heaters and radi-
<br />ator heaters in fireplaces, shall be connected
<br />to the house lines with rigid pipe, semi-rigid
<br />tubing and fittings, or flexible metal tube
<br />connectors with a total length of not more
<br />than 2 feet. The appliance connection to the
<br />house gas piping shall be made with a
<br />ground-joint or gasket union located on the
<br />appliance side of the shut-off valve.

<br />tubing. Gas heat appliances which are mov-
<br />ed occasionally, such as ranges, refrigerators,
<br />clothes driers and hot plates, shall be con-
<br />nected to the house lines with rigid pipe, or
<br />semi-rigid tubing and fittings, or appliance

<br />semi-rigid tubing connector or a flexible
<br />metal tubing connector is used, the connec-
<br />tion shall be made to a house line outlet in
<br />the same room as the appliance. The length
<br />of the connector shall not exceed 6 feet and
<br />it shall be installed so as to be protected
<br />against mechanical injury,
<br />(d) Flexible gas hose. Flexible gas hose
<br />approved by the Building Official may be

<br />used, an approved shut-off valve or gas-cock
<br />shall be installed at the point where the gas
<br />hose is connected to the house gas piping,
<br />Flexible gas hose shall not be concealed from

<br />nections where exposed to view and observa-
<br />tion.
<br />1595.09 Size of piping.
<br />The piping shall be of such size and so in-
<br />stalled as toprovide asupply of gas sufficient
<br />118
<br />to meet the maximum demand without loss
<br />of more than 0,30 inches water column of
<br />pressure between the meter and the appli-
<br />ances. In determining the size of the gas pip-
<br />ing, due consideration shall be given to fu-
<br />ture demands as well as the existing factors
<br />and conditions. The main gas supply line
<br />and the branch line to any central heating
<br />appliance shall be not less than 1-inch di-
<br />ameter pipe. Pipe sizes based on the recom-
<br />mendations of the AGA Reference Manual
<br />for Modern Gas Service and/or the Ameri-
<br />can Standard, Installation of Gas Piping and
<br />Gas Appliances in Buildings, ASA 221.30,
<br />will be accepted as in conformity with this

<br />way or within any other required means of
<br />egress from a building.
<br />(b) Obstructed or unventilated locations,
<br />Gas meters shall not be installed underneath
<br />any stairway, nor in any space which is with-
<br />out adequate provisions for ventilation, nor
<br />in any location where the use of the space or
<br />premises may cause access thereto to be ob-
<br />structed,
<br />(c) Under basementless floors. Gas serv-
<br />ice piping shall not be installed through or
<br />under a crawl space under a first floor or
<br />basement floor construction, or under a floor
<br />laid directly on the ground or fill, except by
<br />special permission from the Building Of-
<br />ficial.
<br />(d) Concealed piping. No pipe smaller
<br />than standard 1/z inch iron pipe size shall be
<br />used in any concealed location. Concealed
<br />piping shall be located in hollow rather than
<br />in solid partitions. Piping to be concealed
<br />shall not use, unions, running threads, right
<br />and left couplings, bushings or swing joints
<br />made by combination of fittings. When
<br />necessary to insert fittings in piping which
<br />has been installed in a concealed location,
<br />the piping maybe reconnected by the use of
<br />a ground joint union with the nut center-
<br />punched or otherwise set to prevent loosen-
<br />ing.
<br />(e) In solid floors, earth or cinders. Pip-
<br />ing in solid floors, such as concrete, shall be
<br />laid in channels in the floor suitably covered
<br />to permit access to the piping with a mini-
<br />mum of damage to the building. Piping in
<br />contact with earth or other materials which
<br />may corrode the piping shall be protected
<br />against corrosion in a manner approved by
