Vent
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
Vent
DO NOT install the vent terminal under any patio or deck.
To help prevent moisture from freezing on walls and under
eaves, DO NOT locate the vent terminal on the side of a
building with prevailing winter winds.
When terminating the vent and combustion air-inlet pipes
through brick or masonry surfaces, the installation of a rust
resistant sheet metal backing plates behind the vent and
combustion air-inlet terminals are recommended.
DO NOT locate the vent terminal too close to shrubbery, as
flue gasses may damage them.
Caulk all cracks, seams and joints within 6 ft. (1.83 m) of
the vent and combustion air-inlet terminals.
Insulate vent pipe exposed to cold conditions (attics, crawl
spaces, etc.) with inflammable material to help prevent
moisture from accumulating in the vent pipe.
Support horizontal sections of the vent and combustion
air-inlet pipe every 4 ft. (1.22 m). DO NOT rigidly secure
the vent system. Provisions must be made to allow for
expansion and contraction of the vent system.
DO NOT install the vent and combustion air-inlet terminals
less than 1 ft. (30 cm) above grade or average snowfall
whichever is greater.
Permanently seal annular openings around the vent and
combustion air-inlet system penetrations using approved
materials to prevent entry of combustion products into the
building.
Vent Terminal Location Considerations
• DO NOT terminate near soft vents or crawl space or other
area where condensate or vapor could create a nuisance haz-
ard or cause property damage.
• DO NOT locate the exhaust vent terminal where condensate
or vapor could cause damage or could be detrimental to the
operation of regulators, relief valves, or other equipment.
• DO NOT locate the exhaust vent terminal over public area or
walkways where condensate or vapor can cause nuisance or
hazard.
• DO NOT locate the vent terminal in proximity to plants/
shrubs.
