GENERAL MAINTENANCE
Conduct an inspection of the venting system twice a year. 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 cap, and shine a flashlight down the vent. Remove any bird nests, or other 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 condensation can cause caps, pipe and
fittings to corrode. Condensation can be caused by having excessive lateral runs, or too many
elbows.
4. Inspect joints to verify that no pipe sections or fittings have been disturbed and consequently
loosened. Also check mechanical support such as wall straps, or plumbers tape for rigidity.
