NOTES: Venting Notes for Fig. 35---47

1.For common vent, vent connector sizing and vent material: United States--- ---use the NFGC Canada --- ---use the CAN/CSA---B149.1---05

2.Immediately increase to 5---in. or 6---in. (127 or 152 mm) vent connector outside furnace casing when 5---in. (127 mm) vent 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 KGAVG0101DFG, Downflow Vent Guard Kit, is used in the downflow position.

4.Type---B vent where required, refer to Note 1 above.

5.Four ---in. (102 mm) 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 may be 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.

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 applica- tion with furnace elbow turned to left side with the connector elbow outside furnace casing pointing upward. (See Fig. 40.)

Caution!! For the following applications, use the minimum vertical heights as specified below.

For all other applications, follow exclusively the National Fuel Gas Code
