INSTALLATION INSTRUCTIONS
MAINTENANCE
Conduct an inspection of the venting system
semiannually. Recommended areas to inspect
are as follows:
1. Check areas of the Venting System which
are exposed to the elements for corrosion.
These will appear as rust spots or streaks, and
in extreme cases, holes. These components
should immediately be replaced.
2. Remove the Termination Cap, and shine
a flashlight down the Vent. Clean and
remove any deposited or foreign material.
3. Check for evidence of excessive
condensation, such as water droplets
forming in the inner liner, and subsequently
dripping out at joints. Continuous
condensate can cause corrosion of caps,
pipe, and fittings. It may be caused by having
excessive lateral runs, too many elbows, and
exterior portions of the system being exposed to cold
weather.
4. Inspect joints, to verify that no Pipe
Sections or Fittings have been disturbed,
and consequently loosened. Also check
mechanical supports such as Wall Straps, or
plumbers' tape for rigidity.
