WARNING

NOTICE

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.

Do not connect any other appliance to the vent pipe or multiple boilers to a common vent pipe. Failure to comply could result in severe personal injury, death, or substantial property damage.

Installation must comply with local requirements and with the National Fuel Gas Code, ANSI Z223.1 for U.S. installations or CSA B149.1 for Canadian installations.

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 21 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.

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.

6 inch vent

If using the alternate sidewall termination:

3.The air piping must terminate in a down-turned elbow as shown in FIG. 4-1B. 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. 4-1B.

WARNING Do not exceed the maximum lengths of the outside vent piping shown in FIG. 4-1B.

Excessive length exposed to the outside could cause freezing of condensate in the vent pipe, resulting in potential boiler shutdown.
