• there is “water” around the heater just after the heater has been operating,
• there are small, black or red granules on the main burner or top of the heater or
• corroded jacket or vent piping is noted.
any of the above conditions exist • raise the supply air temperature or
• increase stored water temperature or
• increase the size of the tank

materials (stainless steel, PVC etc.) that
will not be affected by the condensation
