• 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.
