connector is required, refer to Note 1 above.
3. Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace, except when
factory--approved Downflow Vent Guard Kit is used in the downflow position. See Specification Sheet for accessory listing.
4. Type--B vent where required, refer to Note 1 above.
5. A 4--in.(102 mm) single--wall (26 ga. min.) vent must be used inside furnace casing and when the factory--approved Downflow Vent
Guard Kit is used external to the furnace. See Specification Sheet for accessory listing.
6. Accessory Downflow Vent Guard Kit required in downflow installations with lower vent configuration. See Specification Sheet for
accessory listing.
7. Chimney Adapter Kit may be required for exterior masonry chimney applications. Refer to Chimney Adapter Kit for sizing and
complete application details. See Specification Sheet 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
_
