The CG gas furnace line ranges from 80-95 percent AFUE. Retrofitting and accessory fit-up are easy due to standard top venting and industry-standard furnace widths of 14.5-17.5 inches and 21 inches, says the company. Toolless entry and self-diagnostics save the contractor time by helping to quickly get to and identify any potential issues. Installation is easy because of a broad offering of standard-efficiency models in every configuration, ensuring the contractor has the right furnace for any application. Every high-efficiency model is qualified for either one- or two-pipe installation, allowing one model to cover both applications. For horizontal applications, a horizontal drain kit is standard. A multispeed blower motor allows the contractor to select the airflow that meets individual customer applications. All high-efficiency models are Energy Star-qualified.
