5. The gaps between the outer pipe of the termina-
tion fitting and the support plates must be sealed
with a high quality silicone caulk. Also apply
the silicone caulk along the outer edge of the
support plates sealing the plates to the wall.
Cutting Termination Fitting to Length
1. Only the termination fitting can be cut to length
if required.
2. Add 3/4” to the required length and mark the
end of the outer pipe.
Measure twice, cut once! Make sure to add
3/4” to the overall required length when cut-
ting both pipes.
3. Cut the pipes using an abrasive cutoff saw or
hacksaw (minimum 32 teeth per inch). Make
sure that the inner pipe remains centered in the
outer pipe while cutting. It may be helpful to
temporarily connect the vent section to be cut
into another vent pipe to keep the center pipe
centered while cutting.
4. Mark the end of the outer pipe at the required
length. The length of the outer pipe should be
3/4” less than the inner pipe.
5. Cut through the outer pipe ONLY using a hack-
saw (minimum 32 teeth per inch), or snips.
6. File off any burrs or rough edges on both pipes.
Clean off any dust or dirt.
7. If the cutting process distorted the roundness of
the pipes, carefully use your thumbs to correct
the distortion.
When cutting or correcting the shape of the
outer pipe, WEAR GLOVES. The ends of the
vent pipes can become very sharp when cut.
NOTICE
WARNING
Adjustable Length Vent/Air System Pipe
The component piping and fittings (exclud-
ing the termination fitting) are not design to
be cut for custom lengths. Cutting the piping
or fittings to length may compromise the vent
seal cause potential vent failure or leakage of
flue gas resulting in death, serious injury or
substantial injury.
1. An adjustable straight vent/air system pipe
length is available for applications that require
custom lengths.
2. The adjustable length vent/air system pipe is
adjustable from a minimum of 12” up to a max-
imum of 16.5”.
3. To adjust the length, firmly grab each end of the
pipe and twist together to shorten or twist apart
to lengthen.
