¾ Single wall vent terminations above the roof line must be at least 3 ft. (.9m) high to a maximum of 6 ft. (1.8m) without the
use of lateral supports and 2 ft. (.61 m) higher than any part of a structure within 10 ft. (3.1 m).
¾ Vertical heights greater than 6ft. above the roof shall be supported by Guy Bands. Fasten Guy wires of stainless steel or
galvanized cable with a minimum capacity of 500 lbs. to each of the four anchor holes that are integral to the guy band
and anchor to the roof structure using the appropriate fastening method.
¾ The total vertical distance of the vent system from appliance flue collar to the rain cap termination and the maximum
length of offsets shall not exceed that specified in the appliance manufacturer’s installation instructions.
¾ All horizontal sections must observe the rules for HORIZONTAL VENTING.
