Through-the-Wall Venting Installation
Cut or drill a hole through the exterior wall, slightly
larger than the diameter of the vent pipe selected.
Extend a section of pipe through the hole to the out-
side and attach the terminating elbow to the exterior
end of the pipe. Connect and secure all piping and
elbows from the power venter to the wall. When the
installation is completed, the vent terminal must be at
two (2) inches (5.1 cm) from the exterior surface of the
wall (
see Figure 8
).
