DIRECT VENT - VERTICAL (CATEGORY I)
TABLE 12. DIRECT VENT (VERTICAL EXHAUST CONFIGURATIONS)
• Connection for the appliance exhaust vent to the stack must be as direct as possible. Maximum and minimum venting length
for Category I appliances shall be determined per the latest edition of the National Fuel Code (U.S.) and CAN/CSA-B149.1
Installation Code (Canada).
• The vent should be installed so as to prevent the accumulation of condensate and, where necessary, have means provided for
drainage of condensate. The horizontal breaching of a vent must have an upward slope of not less than 1/4 inch per linear foot
(2 cm/m) from the boiler to the vent terminal. The horizontal portion of the vent shall be supported to maintain clearances and to
prevent physical damage or separation of joints.
