If a custom length of SC is necessary, a standard vent section can be cut.
1. Measure the distance of the length needed, taking the measurement from the end of one of the outer
jackets to the beginning of the other outer jacket on the section to connect to, (A to B on diagram).
2. Select a section that is longer than the required length.
3. It will be necessary to disassemble the vent prior
to cutting.
Stand the section on end with the holes up. Find
the end of snap ring and pry it out of its groove, being
careful not to damage the ends of the vent pipes.
Pull up on end of the snap ring and pull it out from
the end of the pipe. It may want to spiral out as it is
removed. After the snap ring is removed, the inner
vent pipe can be separated from the outer jacket.
4. Add 2" to the distance measured previously for
the cut length of the outer jacket. Mark a cut line on
the outer jacket on the male end (the end without
holes in it).
An effective way of marking is to run a length of tape
around the section, assuring a square cut.
5. Add 3" to the distance measured previously for
the cut length of the inner vent pipe. Mark a cut line
on the inner vent on the male end (the end without
the red seal).
The inner pipe is always cut 1" longer than the
outer pipe
6. WEAR GLOVES, as cut ends are very sharp.
Cut the pipes with an abrasive cutoff saw, plasma
cutter, or compound snips. If using snips, start the
cut at the male end and follow a spiral path around
the pipe until the cutoff mark is reached. File off any
burrs or rough edges that develop in the cutting
process, and clean off any dust or grit. If the cutting
process distorts the roundness of the pipes, carefully use your thumbs to re-round the ends.
7. Reassemble the inner vent into the outer jacket and reinstall the snap ring into the groove. Push the
inner vent into the outer jacket until the triangle on the inner vent is seated firmly against the bead on
outer jacket. Start one end of the snap ring into the groove of the outer pipe. Slowly turn and feed the
snap ring into the groove in a spiral motion, and continue around the pipe until the snap ring is fully
inserted. Ensure that the triangle on the inner vent is all the way down against the bead of the outer
jacket by pushing in firmly. Also ensure that the snap ring is completely in the groove all the way around
outer jacket.
