Venting Connection

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.
