Notes:

1. The vent for this appliance shall not terminate:

a. Over public walkways; or

b. Near soffit vents of crawl space vents or other areas where condensate or vapor could create a nuisance or hazard or property damage; or

c. Where condensate vapor could cause damage or could be detrimental to the operation of regulators, relief valves, or other equipment.

2. When locating vent terminations, consideration must be given to prevailing winds, location, and other conditions which may cause recirculation of the combustion products of adjacent vents.

Recirculation can cause poor combustion, inlet condensate problems, and accelerated corrosion of the heat exchangers.

3. Avoid venting under a deck or large overhang. Recirculation could occur and cause performance or system problems.
