VENT PIPE TERMINATION

The first step is to determine where the vent pipe will terminate. See Figures 15, 20 and 21. The vent may terminate through a sidewall as shown in Figure 20 or through the roof as shown in Figure 21.

The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the National Fuel Gas Code, (ANSI Z223.1, 12.9.1 through 12.9.4) or the Natural Gas and Propane Installation Code (CAN/CSA-B149.1).

Instructions on proper installation through a sidewall are provided in Figure 15.

Plan the vent system layout so that proper clearances are maintained from plumbing and wiring.

Vent pipes serving power vented appliances are classified by building codes as "vent connectors". Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATING THE NEW WATER HEATER and INSTALLING THE WATER HEATER, and with the National Fuel Gas Code and local codes.
