Venting System Condensation
Condensate formation does not occur in all installations of power vented water
heaters but should be protected against on installations where condensation
can form in the venting system.
Formation of condensation in the venting system of Power Vented water
heaters is dependent upon installation conditions including, but not limited to:
ambient temperature and humidity of installation location,
ambient temperature and humidity of venting space,
vent distance and slope,
and product usage.
