A B-vent installed as described in this section is considered to be an enclosed vent system, and the sizing tables in National Fuel Gas Code, NFPA 54/ANSI Z223.1 - latest edition and in the National Standard of Canada, CAN/CGA B149.1 and CAN/CGA B149.2 - latest editions and amend- ments may be used. - Page 13 NATURAL GAS CONNECTION Refer to Figure 11 for the general layout at the furnace. The following rules apply: 1. Use black iron or steel pipe and fittings for the building piping. 2. Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used.
- Page 14 When the gas piping enters through the left side of the furnace, the installer must supply the following fittings (starting from the gas valve): • Straight pipe to reach the exterior of the furnace (Fig- ures 14 & 15). • A ground joint union, drip leg, and manual shutoff valve must also be supplied by the installer.
