Vent/air termination – sidewall
⚠
WARNING
Sidewall vent and air inlet terminations
must terminate in the same pressure
zone.
f. Do not terminate above any door or window.
Condensate can freeze, causing ice formations.
g. Locate or guard vent to prevent condensate damage
to exterior finishes.
h. Do not locate the terminations over public walkways.
i. Do not locate the terminations near soffit vents,
crawl space vents, or other areas where condensate
or vapor could create a nuisance, hazard, or cause
property damage.
j. Do not locate the terminations where condensate
vapor could cause damage or could be detrimental
to the operation of regulators, relief valves, or other
equipment.
k. Terminations must be located a minumum of 12"
above grade or maximum snow line.

Sidewall Vent Kits
Do not exceed the maximum lengths of the
outside vent piping shown in FIG. 3-1B.
Excessive length exposed to the outside could
cause freezing of condensate in the vent pipe,
resulting in potential water heater shutdown.

⚠
WARNING
If using the alternate sidewall termination:
3. The air piping must terminate in a down-turned elbow as
shown in FIG. 3-1B. This arrangement avoids recirculation
of flue products into the combustion air stream.
4. The vent piping must terminate in an elbow pointed
outward or away from the air inlet, as shown in FIG. 3-1B.

Sidewall Termination
of Air and Vent
Follow instructions below when
determining vent location to avoid
possibility of severe personal injury,
death, or substantial property damage.
A gas vent extending through an exterior
wall shall not terminate adjacent to a wall
or below building extensions such as eaves,
parapets, balconies, or decks. Failure to
comply could result in severe personal
injury, death, or substantial property
damage.
Determine location
Locate the vent/air terminations using the following
guidelines:
1. The total length of piping for vent or air must not exceed
the limits given in the General Venting Section on page
17 of this manual.
2. You must consider the surroundings when terminating
the vent and air:
a. Position the vent termination where vapors will
not damage nearby shrubs, plants or air
conditioning equipment or be objectionable.
b. The flue products will form a noticeable plume as
they condense in cold air. Avoid areas where the
plume could obstruct window views.
c. Prevailing winds could cause freezing of
condensate and water/ice buildup where flue
products impinge on building surfaces or plants.
d. Avoid possibility of accidental contact of flue
products with people or pets.
e. Do not locate the terminations where wind eddies
could affect performance or cause recirculation,
such as inside building corners, near adjacent
buildings or surfaces, window wells, stairwells,
alcoves, courtyards, or other recessed areas.
