Negative or Positive Vent Kit?
Negative means that even if fans or blowers are used in an appliance or vent system, venting is accomplished by natural draft. Natural draft is created by temperature difference and the height of the vent. (The vent pressure is lower than atmospheric).
Positive means that fans, blowers or other means are used to propel vent gases through the vent at above atmospheric pressure.
