Note: Do NOT over-tighten the band clamps. Follow the
Torque guidelines in Table 1.
3. If you’re using air-testable entry boots, check the
system integrity by attaching a TRK-200 (Test
Regulator Kit) to the ducted entry boot (DEB) or
ducted bulkhead boot (DBB) air tting and charge
the lines to 2 to 4 PSI. Expect some initial line
expansion which will result in some pressure loss.
After the line pressure has stabilized, test the line
for 30 minutes with no pressure drop.
4. Soap all of the boot/ducting interfaces to check for
leaks. If any leaks are found, tighten the clamps
and retest.
Do NOT over-tighten the band clamps.
5. After installation is complete, the backlling
process can begin. Only backll with pea gravel,
clean compacted sand or crushed stone when
using DUCT-400-XXX ducting.
6. If you’re using air-testable boots, recheck the air
test after backlling to conrm system integrity.

Measure and Install XP Piping
1. Run a measuring tape / line through the duct, pull it tight and measure the distance from the Pipe Termination Collars.
Figure 3: Pipe Termination Collar Location
CAUTION: Do NOT cut the pipe longer than required. Excess pipe inside of ducting can cause pipe movement due to
line shock.
2. Cut the pipe to the measurement from step 1.
3. Remove the duct from the entry boots.
4. Extend the pipe through the ducting.
Note: Attach a rounded object to the end of the pipe to keep it from catching on the ducting ribs as it moves through.
5. Push the pipe through the entry boots.
6. If the necessary tting connections or test boots have not already been installed, then do so now.
7. Attach the piping to the tting.
