GENERAL MAINTENANCE
Inspect venting system semi-annually as
follows:
1. Check for corrosion areas of the venting
system exposed to the elements. These
will appear as rust spots or streaks
and, in extreme cases, holes. Damaged
components should be replaced
immediately.
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
condensate, such as water droplets
forming in the inner liner and subsequently
dripping out at joints. 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.
A removable panel or other means must be
provided in the enclosure for visual inspection
of the flue connection.
NOTICE:
This also pertains to vertical vent
systems installed on the outside of the building.
Venting termination shall not be recessed into
a wall or siding.
Slide the vertical vent cap over the ends of the
vent pipe and secure. See
