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 rust-resistant sheet metal backing plate
(1 x 1 foot) (30 x 30 cm) is recommended behind vent. (See
Figure.)
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 water heaters exposed to cold
conditions (attics, crawl spaces, etc.) with inflammable
material to help prevent moisture from accumulating in vent
pipe. The insulation should be rated for the temperature and
should not contain substances that corrode the vent pipe.
Do Not extend exposed vent pipe of water heaters outside of
building.
Guard vent against accidental contact with people and pets.
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

WARNING
:
For multiple unit installation, a minimum
distance between vent terminations must be maintained to
prevent recirculation of vent gases. Maintain a center-to-
center distance between vent terminations of 19 inches (48
cm) for two unit installation. Maintain a center-to-center
distance between vent terminations of 21 inches (53 cm) for
three or more unit installation.
