The lower portion of the vent system must
be supported and restopped per appliable
DuraVent instruction.
MAINTENANCE
Have your venting system checked annually.
This can be done easily by the same
technician who inspects & services the
appliance. Recommended areas to inspect
are as follows:
- Check areas of the Venting System which
are exposed to the elements for wear or
damage. If damage is found, the components
should be replaced immediately.
- Where possible, look into the Termination
Cap to verify no foreign material is there to
block the vent. Remove any foreign material
found.
- Where practical, inspect joints to verify
that no Pipe Sections or Fittings have been
disturbed, and consequently loosened. Also
check mechanical supports such as Wall
Straps, support plates, etc for rigidity.
