WARNING: Moisture in the flue gas will condense as it leaves the vent terminal. In cold weather this condensate can freeze on the exterior wall, under the eaves and on surrounding objects. Some discoloration to the exterior of the building is to be expected. However, improper location or installation can result in severe damage to the structure or exterior finish of the building
Additional Considerations
Do Not install vent terminal under any patio or deck.
To help prevent moisture from freezing on walls and under eaves, do not locate vent terminal on the side of a building with prevailing winter winds.
To help prevent water lines from freezing do not locate vent terminal on the side of a building with prevailing winter winds.
Do Not terminate vent directly on brick or masonry surfaces. A
(2 x 2 feet) (60 x 60 cm) is recommended behind vent. (See illustration.)
Do Not locate vent terminal too close to shrubbery, as flue gasses may damage them.
Caulk all cracks, seams and joints within six (6) feet (1.8 m) of vent terminal.
Caulk around thimble face plate for weather tight seal.
All painted surfaces should be primed to lessen the chance of physical damage. Painted surfaces will require maintenance.
Insulate vent pipe of indoor water heaters exposed to cold conditions (attics, crawl spaces, etc.) with inflammable material to help prevent moisture from accumulating in vent pipe.
Do Not extend exposed vent pipe of indoor water heaters outside of building.
Guard vent against accidental contact with people and pets.
