VENTING & AIR INLET PIPING
• Do not locate the exhaust exit terminal over
public walkways where condensate could drip
and create a hazard or nuisance.
• When adjacent to public walkways, locate the
exit terminal at least 7 feet above grade.
• Do not locate the exhaust termination directly
under roof overhangs to prevent icicles from
forming or recirculation of exhaust gases from
occurring.
• Provide 3 feet clearance from the inside corner
of adjacent walls.
b. Figure 3.3, 3.4 and 3.5 show approved sidewall
venting configurations using standard PVC or
CPVC fittings. A similar configuration using
FasNSeal stainless steel exhaust pipe can be used
with either PVC or other approved material for the
combustion air intake piping.
8. Figures 3.6 through 3.8 show recommended vertical
venting configurations.
a. Figure 3.6 illustrates a vertical venting
configuration using PVC inlet and exhaust. A
similar configuration can be constructed using a
FasNSeal stainless steel vent termination. PVC or
other approved materials may be used for air inlet
piping.
i. The opening of the air inlet piping is to be
a minimum of 12” (300 mm) above the
expected snow accumulation on the roof
surface.
ii. Locate the opening of the exhaust vent pipe a
minimum of 12” above the air inlet opening
to prevent flue gas from recirculating to the air
inlet.
b. Figure 3.7 shows vertical exhaust venting through
an unused chimney. In this case, combustion air
is supplied from inside the building. Section 1.D
provides guidelines for determining adequate
inside air.
c. Figure 3.8 illustrates another vertical venting
configuration through an unused chimney. In
this arrangement the combustion air is supplied
through the chimney as well.

Condensing flue gases can freeze on exterior
building surfaces which may cause discoloration and
degradation of the surfaces.
