The furnace is factory-shipped for usewith natural gas. An A.G.A/C.G.A certified gas conversion kit isrequired to convert furnace for use with propane gas. Thesefurnaces are suitable for installation in a residence built on site ora manufactured residence completed at final site. The design ofthis furnace line is NOT A.G.A./C.G.A. certified for installation inrecreation vehicles, in manufactured (mobile) homes, or outdoors.These furnaces SHALL NOT be installed directly on carpeting,tile, or any other combustible material other than wood flooring. Indownflow installations, factory accessory floor base MUST beused when installed on combustible materials and wood flooring.These furnaces are shipped with the drain and pressure tubesconnected for UPFLOW applications. Minor modifications arerequired when used in DOWNFLOW, HORIZONTAL RIGHT, orHORIZONTAL LEFT (supply-air discharge direction) applica-tions as shown in Fig. 1. See details in Applications section.These furnaces are shipped with the following materials to assist inproper furnace installation. These materials are shipped in the mainblower compartment.Installer Packet includes:Installation, Start-Up, and Operating InstructionsService and Maintenance InstructionsUser’s Information ManualWarranty CertificateLoose Parts Bag includes: QuantityPressure tube extension 1Collector box or condensate trap extension tube 1Inducer housing drain tube 11/2-in.
