Multi Vent Termination Clearances

When two (2) or more furnaces are vented near each other, each furnace must be individually vented.

Two (2) vent terminations may be installed as shown in Figure 23, Figure 24, Figure 25, Figure 26, Figure 27 and Figure 28, but the next vent termination must be at least 36" away from first 2 ter- minations. It is important that vent terminations be made as shown

to avoid recirculation of flue gases.
