B149.1-00.
2. Immediately increase to 5–inch or 6-inch vent connector ourside furnace casing when 5-inch vent connector required, refer to Note 1 above.
3. Side outlet vent for upflow and downflow installaitons must use Type B vent immediately after exiting the furnace, except when
KGAVG0101DFG, Accessory downflow vent gurad kit, is used in the downflow position.
4. Type-B vent where required, refer to Note 1 above.
5. 4" single-wall (26 ga. min.) vent must be used inside furnace casing and when the KGAVG0101DFG Downflow Vent Guard Kit is used external
to the furnace.
6. Accessory Downflow Vent Guard Kit, KGAVG0101DFG required in downflow installations with lower vent configuration.
7. Chimney Adapter Kit required for exterior masonry chimney applications. Refer to Chimney Adapter Kit, KGACA02014FC or
KGACA02015FC, for sizing and complete application details.
8. Secure vent connector to furnace elbow with (2) corrosion-resistant sheet metal screws, spaced approximately 180° apart.

ADDITIONAL VENTING REQUIREMENTS

A 4" round vent elbow is supplied with the furnace. A 5 inch or 6
inch vent connector maybe required for some model furnaces. A
field-supplied 4 inch to 5 inch or 4 inch to 6 inch sheet metal
increaser fitting is required when 5 inch or 6 inch vent connector
is used. See Fig. 34-46, Venting Orientation for approved vent
configurations.
NOTE: Vent connector length for connector sizing starts at
furnace vent elbow. The 4 inch vent elbow is shipped for upflow
configuration and may be rotated for other positions. Remove the
3 screws that secure vent elbow to furnace, rotate furnace vent
elbow to position desired, re-install screws. The factory-supplied
vent elbow does NOT count as part of the number of vent
connector elbows.
The vent connector can exit the door through one of 5 locations on
the door.
