1. Follow all instructions provided with the concentric
termination kit. The following are general guidelines
for information only
2. See Figure 50 for the typical assembly of a concentric
termination assembly.
3. Prepare the bird screen, Item 4 (purchase separately if
not included with the kit). Cut the bird screen to size
if required. If the bird screen must be trimmed, cut the
bird screen to fit the outside diameter of the PVC inner
pipe supplied with the termination kit.

6 Finished assembly
install the rain cap and bird screen
until the assembly has been inserted through
the roof (or sidewall) and all supports have
been installed. Follow instructions to cover
the end of the assembly with plastic before
inserting through the roof penetration to
prevent debris from blocking the air passages.
If necessary, you can shorten the lengths
of the inner and outer pipes for a shorter
finished assembly. But you must ensure the
pipes butt correctly at both ends. Failure to
properly assemble the concentric termination
can result in flue gas recirculation, causing
possible severe personal injury or death.
For polypropylene applications, See venting
and air piping notes on page 21.
