￿WARNING

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 16 of this manual.

￿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.
