MOISTURE IN THE FLUE GASES CONDENSES AS IT LEAVES THE TERMINAL. THIS MOISTURE
CAN FREEZE ON EXTERIOR WALLS, ON SOFFITS, AND OTHER NEARBY OBJECTS. SOME
DISCOLORATION IS TO BE EXPECTED; HOWEVER, IMPROPER LOCATION OR INSTALLATION CAN
CAUSE STRUCTURAL OR EXTERIOR FINISH DAMAGE TO THE BUILDING.
Caulk all cracks, seams or joints within a 6 foot (1.8m) radius of the termination.
Do not terminate under a deck unless there is adequate clearance to prevent damage from the fl ue gases.
A termination may be located at the end of a patio deck. Piping running beneath the deck must be suitably
insulated and suspended in a manner to prevent condensate from collecting and freezing.
Do not locate the terminal on the side of the building facing the prevailing winter winds.
