15-26-390 Housing of generators.

   Stationary acetylene gas generators shall be installed in a suitable building which shall be constructed and maintained in accordance with the building provisions of this Code applicable to buildings housing such apparatus.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-400 Piping and relief valves.

   The connections from generators to service pipes shall be made with right and left thread nipples or long thread nipples with locknuts or approved unions. Unions depending on gaskets to make tight are prohibited in pipe sizes under two and one-half inches. Piping shall be arranged so that any moisture will drain to the generator, drip pots or seals. Each generator shall be provided with a gas escape or relief pipe to take care of over- or after-generation. Such gas escape or relief pipes shall be of galvanized iron of the following sizes:

 

Size of Machine (pounds)	Minimum Diameter of Pipe
Up to 25 inclusive	3/4 inch
26 to 100 inclusive	1 1/4 inch
101 to 200 inclusive	1 1/4 inch
Over 200	1 1/2 inch

 

   The relief pipe shall be made as short and as free from bends as practicable. However, if it is more than 50 feet in length or has more than four right-angle bends, a pipe of one size larger than that required by this table shall be used. It shall be substantially installed without traps and in such manner that any condensation will drain back to the generator or its component parts. It shall be carried to a suitable point outside the building and shall terminate in an approved hood or bend at least 12 feet above the ground and remote from windows or other openings into buildings, and shall be so constructed that it cannot be obstructed by rain, snow, ice, insects or birds.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-410 Water supply connections.

   In cases where the generators are supplied with water from city mains or house pipes, and where dangerous pressures might be built up, no direct pipe connection with the generator shall be permitted. In such cases the supply pipe shall terminate some distance above the regularly provided opening for filling, so that water can be observed as it enters the generator.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-420 Drain connections.

   Machines of carbide-feed type shall not be fitted with continuous drain connections leading to sewers, but shall discharge into suitable open receptacles which may have such connections.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-430 Gasometers.

   Gasometers, if used, shall be of the liquid-sealed inverted bell type, of such design that a pressure in excess of 15 pounds cannot be obtained.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-440 Portable generator – Defined.

   “Portable generator” means an acetylene generator of not more than 30 pounds carbide capacity, which has been approved for portable use by the Underwriters Laboratories and included in the “List of Inspected Gas, Oil and Miscellaneous Appliances” dated November, 1973, of low-pressure and medium pressure acetylene generators.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-450 Portable generator – Permit required.

   Portable generators shall not be installed or used inside of buildings unless a permit for such use in said location shall first be secured from the fire commissioner. It shall be the duty of the fire commissioner to inspect the premises wherein such generator is to be used, before issuing such permit. The person applying for a permit shall pay the comptroller a fee of $3.00 for such inspection. Should the inspection show compliance with the provisions of this section, the fire commissioner shall issue a permit for such installation and use.
