required, refer to Note 1 above.
3. Side outlet vent for upflow and downflow installations nmst use Type B vent immediately after exiting the furnace, except when
factory-approved Downflow Vent Guard Kit, is used in the downflow position. See Table 18 for accessory listing.
4. Type-B vent where required, refer to Note 1 above.
5. Four-in. (102 ram) single-wall (26 ga. rain.) vent nmst be used inside furnace casing and when the factory-approved Downflow Vent
Guard Kit is used external to the furnace. See Table 18 for accessory listing.
6. Accessory Downflow Vent Guard Kit required in downflow installations with lower vent configuration. See Table 18 for accessory

7. Chinmey Adapter Kit may be required for exterior masonry chinmey applications. Refer to Chinmey Adapter Kit for sizing and
complete application details. See Table 18 for accessory listing.
8. Secure vent connector to furnace elbow with (2) corrosion-resistant sheet metal screws, spaced 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.
10. The total height of the vent and connector shall be at least seven feet (2 M) for the 154,000 Btuh gas input rate model when installed
in a downflow application with furnace elbow turned to left side with the connector elbow outside furnace casing pointing upward.
