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.
