Through the Wall Venting with Low Ground Clearance
When venting cannot exit through the wall at a height greater than or equal to 12 in (30.5 cm) (and above
expected snow level) from the ground, then the installation must be modified as shown below (see Figure 14).
Refer to Table 3 (page 27) for maximum venting lengths using 4 in (10.2 cm), or 6 in (15.2 cm) diameter plastic
pipe. When using low ground clearance venting there still needs to be 36 in (91.5 cm) of vent separation
between intake and exhaust vent terminations.
