linear foot (305 mm) from the heater to the vent terminal.
The horizontal portions of the vent shall also be supported
for the design and weight of the material employed to
maintain clearances and to prevent physical damage or
separation of joints.

Termination
The vent terminal should be vertical and should terminate
outside the building at least 3' (0.91 m) above the highest
point where it passes through the roof and 2' (0.61 m)
above the highest point of the roof or building that is within
10' (3 m) horizontally. The vent cap should have a minimum
clearance of 4' (1.2 m) horizontally from and in no case
above or below (unless a 4' (1.2 m) horizontal distance
is maintained) electric meters, gas meters, regulators and
relief equipment.
The distance of the vent terminal from adjacent public
walkways, adjacent buildings, open windows and building
openings must be consistent with the NFGC (U.S.) or B149
(Canada). Vents supported only by flashing and extending
above the roof more than 5 ft (1.5 m) should be securely
guyed or braced to withstand snow and wind loads.
NOTE: When using PVC Tee vent as termination, insert
the round stainless mesh screens provided with the unit
into the tee ends.
