VENTING NOTES FOR FIG. 35 - 47

1.For common vent, vent connector sizing and vent material: United States-use the NFGC.

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 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 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 Table 18 for accessory listing.

6.Accessory Downflow Vent Guard Kit required in downflow installations with lower vent configuration. See Table 18 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 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. (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
