b. Near soffit vents or crawl space vents or other areas where condensate or vapor could create anusiance or hazard or property damage; or
c. Where condensate vapor could cause damage or could be detrimental to theoperafion of regulators, relief valves, or other equipment.

Recirculafion cancause poor combustion, inlet condensate problems, and accelerated corrosion of the heat exchangers.
