It details the methodology for identifying existing unit curb dimensions, adapter bottom and top specifications, and duct positioning. The manual explains the specific architectural symbols used for supply and return ducts, as well as the representation of galvanized standing seam insulated panels. Furthermore, it outlines how plan views and profile sections illustrate air transition details, ensuring accurate installation and mitigation of risks during HVAC retrofit projects. The guide emphasizes the importance of understanding these blueprints to streamline the retrofit process, providing essential contact information for professional support and consultation. By standardizing the interpretation of these drawings, the guide helps contractors and dealers effectively manage the technical complexities associated with unit curb adapters and roof-mounted HVAC installations, ultimately reducing potential field errors and operational risks.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/reading-curbco-submittal-drawings-hvac-retrofit-guide/663851/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/reading-curbco-submittal-drawings-hvac-retrofit-guide/663851.png","ImageObject",300,407,{"name":42,"@type":43},"Hazel","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":52,"interactionType":53,"userInteractionCount":26},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What does the solid line represent in a CURBCO submittal drawing?","Question",{"text":62,"@type":63},"The solid line represents the outline of the Adapter Bottom that sits on the old curb, as well as the existing duct openings.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"How are the new unit curb dimensions represented in the drawings?",{"text":67,"@type":63},"The Adapter Top, or new unit curb, is represented by a double line with slashes in-between, with dimensions indicated to the right and on the bottom of the drawing.",{"name":69,"@type":60,"acceptedAnswer":70},"What is the purpose of the galvanized standing seam insulated panels shown in the drawings?",{"text":71,"@type":63},"These panels, represented by a dash-dot line pattern, cover areas of the old curb that are not covered by the Curb Adapter; it is important to note that these are not intended to be used as work platforms.","https://schema.org",{"og:url":32,"og:type":74,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":76,"canonical":32},"index,follow",{"doc_id":78,"site_id":7},663851,1793232852,{"code":4,"msg":81,"data":82},"success",[83,87,91,95,100,105,110,114,119,122,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":84,"show_sort_weight":85,"slug":86},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":88,"show_sort_weight":89,"slug":90},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":92,"show_sort_weight":93,"slug":94},"Exam",70,"exam",{"id":96,"doc_module":4,"doc_module_name":25,"category_name":97,"show_sort_weight":98,"slug":99},5,"Comic",60,"comic",{"id":101,"doc_module":4,"doc_module_name":25,"category_name":102,"show_sort_weight":103,"slug":104},6,"Technology",50,"technology",{"id":106,"doc_module":4,"doc_module_name":25,"category_name":107,"show_sort_weight":108,"slug":109},7,"Healthcare",40,"healthcare",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":112,"slug":113},8,30,"research-report",{"id":115,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},9,"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":96,"slug":129},19,"General","general",{"code":4,"msg":81,"data":131},{"doc_id":78,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":111,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":26,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":139,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":12,"update_tm":79,"read_time":30},137441390410,"https://ap-avatar.wpscdn.com/avatar/2000252f4ab5702993?_k=1776741390130283984","Reading CURBCO Submittal Drawings  \nOur current Submittal drawing is a Plan View of the old and new unit curbs.  \n1. We start with the old or existing unit curb dimensions. We take the outside diameter (O. D. ) of the old curb and add grow it 2”. This is to allow for tar and other roofing buildup around the unit. The dimensions at the top and down the left side of the drawing are the O. D. of the Adapter Bottom that will be sitting on the old curb. The outline of the Adapter Bottom is a solid line. The existing duct openings are solid lines, with the EXISTING SUPPLY and EXISTING RETURN in the appropriate square or rectangle with their dimensions.  \n2. A double line with slashes in-between represents the Adapter Top (the new unit curb) . The dimensions immediately to the right and on the bottom of the drawing are the Inside Diameter ( I. D. ) of the Adapter Top. The duct supports are also shown as double lines filled with slashes. The supply duct is marked with an “X” in dashed line and the return duct is marked with a “/”in dashed line similar to engineering blueprints.  \n3. The areas of the old curb that will not be covered by the Curb Adapter (if any) are covered with an 18 gauge galvanized standing seam insulated panel or panels. These panels are not work platforms. ***IMPORTANT*** These areas are shown as lines with a dash dot pattern.  \n4. The drawings on the right and bottom of the Plan View show the profiles through the adapter. These views give the details of the transitioning of the air from the new unit down to the old curb and the overhang (if any) there will be beyond the perimeter of the existing curb.  \n***IMPORTANT***  \n5. Please feel free to call any time! There are no emergencies while the adapter is still on paper. We can talk you or your contractor/dealer.  \nWe take the Hassle and Risk out of the HVAC retrofit business!  \n7960 Fallbrook Dr. | Houston, TX 77064 | 281-469-8855","cbCaijfGuJbuxeKL","https://ap.wps.com/l/cbCaijfGuJbuxeKL","pdf",154332,"English","# Reading CURBCO Submittal Drawings\n## Technical Specifications and Blueprint Symbols\n## Installation and Support Information","[{\"question\":\"What does the solid line represent in a CURBCO submittal drawing?\",\"answer\":\"The solid line represents the outline of the Adapter Bottom that sits on the old curb, as well as the existing duct openings.\"},{\"question\":\"How are the new unit curb dimensions represented in the drawings?\",\"answer\":\"The Adapter Top, or new unit curb, is represented by a double line with slashes in-between, with dimensions indicated to the right and on the bottom of the drawing.\"},{\"question\":\"What is the purpose of the galvanized standing seam insulated panels shown in the drawings?\",\"answer\":\"These panels, represented by a dash-dot line pattern, cover areas of the old curb that are not covered by the Curb Adapter; it is important to note that these are not intended to be used as work platforms.\"}]","Reading CURBCO Submittal Drawings - HVAC Retrofit Guide | PDF"]
