Venting Notes1. For common vent, vent connector sizing and vent material: United States, latest edition of the National Fuel GasCode (NFGC), ANSI Z223.1/NFPA 54.
2. Immediately increase to 5-in. (127 mm) vent connector outside furnace casing when 5-in. (127 mm) vent connectorrequired, refer to Note 1.
3. Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace,except when Downflow Vent Guard is used in downflow position.
4. Type B vent where required, refer to Note 1.5. 4--- in. (102 mm) single wall vent must be used inside furnace casing and the Downflow Vent Guard Kit.6. Accessory Downflow Vent Guard Kit, required in downflow installations with bottom vent configuration.7. Chimney Adapter Kit required for exterior masonry chimney applications. Refer to Chimney Adapter Kits for sizingand complete application details.
8. Secure vent connector to furnace elbow with (2) corrosion-resistant sheet metal screws, space approximately 180°apart.
9. Secure all other single wall vent connector joints with (3) corrosion-resistant screws spaced approximately 120°apart. Secure Type B vent connectors per vent connector manufacturer’s recommendations.

NOTES:1. Two additional 7/8---in. (22 mm) diameter holes are located in the top plate.2. Minimum return ---air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s recommendations for equivalent diameters.a. For 800 CFM---16---in. (406 mm) round or 14 1/2 x 12---in. (368 x 305 mm) rectangle.b. For 1200 CFM---20---in. (508 mm) round or 14 1/2 x 19 1/2---in. (368 x 495 mm) rectangle.c. For 1600 CFM---22---in. (559 mm) round or 14 1/2 x 22 1/16---in. (368 x 560mm) rectangle.d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific use of single side inlets. The use of both side inlets,a combination of 1 side and the bottom, or the bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
