<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> (34) Paragraph 22. 2. 20 shall be added immediately <br /> after Paragraph 22. 2. 19 as follows: <br /> <br /> "22.2.20 Gas Company Regulations: No <br /> person, Eirm or coraoration other than Gas <br /> Company employees or agents shall connect or <br /> disconnect customer-owned piping to or from <br /> Gas Company-owned lines. The Gas Company <br /> shall decide and designate in every case the <br /> type of gas meter to be set, where the meter <br /> shall be located, and the point at which the <br /> customer-owned piping shall be connected to <br /> the Gas Company -owned lines. The plumber <br /> shall first ascertain this information from the <br /> Gas Company before installing a proper meter <br /> loop or extending the customer -owned piping to <br /> the point of connection. " <br /> (35) In Paragraph 22. 6. 1 Subparagraph C shall be <br /> deleted, and Subparagraph B shall be changed to read <br /> as follows: <br /> <br /> "B. Where appliances are installed in a <br /> confined space within a building of unusually <br /> tight construction, air for combustion and ven- <br /> tilation must be obtained from outdoors or from <br /> spaces freely communicating with the outdoors. <br /> (Crawl space, attic, or open air. ) Under these <br /> conditions, there shall be two openings having a <br /> combined free area of not less than one square <br /> inch per 1000 BTU per hour of input rating. <br /> One opening shall be near the top of the enclo- <br /> sure and one near the bottom. These openings <br /> shall be of approximately equal area and shall <br /> communicate with the selected source, or <br /> sources of adequate air supply, by ducts. Ducts <br /> shall be continuous and of the same cross - <br /> sectional area as the openings to which they <br /> connect. The minimum dimensions of rec- <br /> tangular air ducts shall be not less than 3 inches. <br /> Return-air connections in the furnace room, or <br /> directly above or below the furnace room shall <br /> be made as to preclude any possibility of air <br /> being drawn from the furnace room into the <br /> return-air duct or open living area by action of <br /> the furnace fan. The furnace room door or <br /> doors must be solid, reasonably tight without <br /> vents or other means of allowing combustion <br /> air to be secured from the living area. " <br /> <br /> (36) Figure 2, Page 72 shall have deleted therefrom <br /> all references to combustion air vents in and above the <br /> door. <br />
