It tests inspection frequency, pipe support spacing, make-up air definitions, required dimensions for outdoor openings, conduit extension rules, protective shielding thickness, threaded pipe lengths, and meter descriptions. Additional questions address indoor combustion air volume calculations, label spacing for exposed piping, shut-off valve placement, venting system types, pilot function, garage installation clearance, attic service space, drain line sizing, fuel connector maximum length, and mechanical draft exit terminal heights.",{"@graph":69,"@context":119},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/ifgc-practice-test/319725/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/ifgc-practice-test/319725.png","ImageObject",300,407,{"name":92,"@type":93},"Tawan","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-06","2026-09-20",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",14,{"@type":107,"mainEntity":108},"FAQPage",[109,115],{"name":110,"@type":111,"acceptedAnswer":112},"How many inspections are required by code in this practice test?","Question",{"text":113,"@type":114},"The correct answer is 3.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"What type of venting system does not depend on a fan or power to remove flue gases?",{"text":118,"@type":114},"Natural draft does not depend on a fan or power.","https://schema.org",{"og:url":83,"og:type":121,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":123,"canonical":83},"index,follow",{"doc_id":125,"site_id":62},319725,1790763817,{"code":4,"msg":5,"data":128},{"doc_id":125,"user_id":129,"nickname":92,"user_avatar":130,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":131,"file_id":132,"file_url":133,"file_type":134,"file_size":135,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":19,"language":136,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":137,"faqs":138,"seo_title":139,"seo_description":67,"update_tm":140,"read_time":52,"preview_page_count":4},2336475104042,"https://ap-avatar.wpscdn.com/avatar/22000c4c32af1715be0?x-image-process=image/resize,m_fixed,w_180,h_180&k=1786537525561427321","IFGC Practice Test  \n1.
