Available Manufacturers: Subject to compliance with requirements, manufacturers offering piping <br /> connectors which may be incorporated in the work include, but are not limited to, the following: <br /> Fernco, Inc. <br /> PART 3-EXECUTION <br /> 3.1 INSTALLATION <br /> A. Install pipe, tube and fitting in accordance with recognized industry practices which will achieve <br /> permanently leak proof piping systems, capable of performing each indicated service without <br /> piping failure. Install each run with minimum joints and couplings, but with adequate and <br /> accessible unions for disassembly and maintenance/replacement of valves and equipment. <br /> Reduce sizes (where indicated) by use of reducing fittings. Align piping accurately at <br /> connections, within 1/16" misalignment tolerance. Comply with ANSI B31 Code for pressure <br /> piping. <br /> B. Locate piping runs vertically and horizontally (pitched to drain) and avoid diagonal runs wherever <br /> possible. Orient horizontal runs parallel with walls and column lines. Locate runs as shown or <br /> described by diagrams, details and notations or, if not otherwise indicated, run piping in shortest <br /> route which does not obstruct usable space or block access for servicing building and its <br /> equipment. Hold piping close to walls, overhead construction, columns and other structural and <br /> permanent enclosure elements of buildings; limit clearance to 1/2" where furring is shown for <br /> enclosure or concealment of piping, but allow for insulation thickness, if any. Where possible, <br /> locate insulated piping for 1.0" clearance outside insulation. Wherever possible in finished and <br /> occupied spaces, conceal piping from view, by locating in column enclosures, in hollow wall <br /> construction or above suspended ceilings; do not encase horizontal runs in solid partitions, <br /> -- except as indicated. <br /> CEA#18010 HVAC PIPE, TUBE AND FITTINGS 2321 01 -3 <br /> COPYRIGHT©2018 CONSULTING ENGINEERING ASSOCIATES, INC. <br />
