7. If intake and exhaust piping must be run up a side wall to
position above snow accumulation or other obstructions,
piping must be supported every 24” (610 mm) as shown
in Figures 34 and 35.
When exhaust and intake piping must be run up an
outside wall, the exhaust piping must be terminated
with pipe sized per Table 10. The intake piping may be
equipped with a 90° elbow turndown. Using turndown
will add 5 feet (1.5 m) to the equivalent length of the
pipe.
8. Based on the recommendation of the manufacturer, a
multiple furnace installation may use a group of up to
four terminations assembled together horizontally, as
shown in Figure 38.

TABLE 10
1
The exhaust termination tee should be connected to the 2" or 3" PVC flue pipe as shown in the illustration. Do
not use an accelerator in applications that include an exhaust termination tee. The accelerator is not required.
2
As required. Flue gas may be acidic and may adversely affect some building materials. If a side wall vent
termination is used and flue gases will impinge on the building materials, a corrosion−resistant shield (24 inches
square) should be used to protect the wall surface. If optional tee is used, the protective shield is recom-
mended. The shield should be constructed using wood, sheet metal or other suitable material. All seams, joints,
cracks, etc. in affected area, should be sealed using an appropriate sealant.
3
Exhaust pipe 45° elbow can be rotated to the side away from the combustion air inlet to direct exhaust away
from adjacent property. The exhaust must never be directed toward the combustion air inlet.
