Venting
General
CAUTION: Proper installation of flue venting is criti- cal for the safe and efficient operation of the heater.
Definition of Appliance Categories
Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.
Category I. A heater which operates with a
Category II. A heater which operates with a
Category III. A heater which operates with a positive vent pressure and with a vent gas temperature that avoids excessive condensate production in the vent.
Category IV. A heater which operates with a positive vent pressure and with a vent gas temperature that may cause excessive condensate production in the vent.
See Table H for appliance category requirements for the Hi Delta.
NOTE: For additional information on appliance categorization, see appropriate ANSI Z21 Standard and the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.
Determination of Appliance Category for Venting Purposes and Venting Arrangements
WARNING: Contact the manufacturer of the vent material if there is any question about the appliance categorization and suitability of a vent material for application on a Category III or IV vent system. Using improper venting materials can result in personal injury, death or property damage.
