Assemble Pipe Sections
Insert the inner fl ue of section A into the fl ared inner fl ue of
section B.
Start the outer fl ue of section A over the outer fl ue of section
B (see Figure 8.2).
Once both inner and outer fl ues are started, press section
A onto section B fi rmly until all lances have snapped into
place. Check to make sure they have snapped together (see
Figure 8.3) and the seams are not aligned (see Figure 8.4).
Tug slightly on section A to con
fi rm it has completely locked
into place. It is acceptable to use screws no longer than 1
in. (25 mm) to hold outer pipe sections together. If predrilling
holes, do NOT penetrate inner pipe
For 90° and 45° elbows that are changing the vent direction
from horizontal to vertical, one screw minimum should be
put in the outer
fl ue at the horizontal elbow joint to prevent
the elbow from rotating. Use screws no longer than 1 in. (25
mm). If predrilling holes, do NOT penetrate inner pipe.
