CAUTION
Under certain climatic conditions some building materials
may be affected by flue products expelled in close
proximity to unprotected surfaces. Sealing or shielding of
the exposed surfaces with a corrosion resistant material
(e.g. aluminum sheeting) may be required to prevent
staining or deterioration. The protective material should
be attached and sealed (if necessary) to the building
before attaching the vent termination. It is strongly
recommended to install the vent termination on the
leeward side of the building.
