HORIZONTAL TERMINATIONS
Graph 1 Horizontal Termination Graph
HORIZONTAL
Graph 1 shows the maximum horizontal vent run (to the outside wall) for the corresponding vertical vent rise. The allowable
venting conguration MUST be within the shaded area. A power vent system is available for congurations which are not allowed
by these requirements.
• When using a wall-mounted termination, a maximum of 3 elbows (45° or 90°) may be used.
• For each second or third elbow:
- 20”/500 mm must be subtracted from the horizontal length allowance when using a 45° elbow
- 40”/1000 mm must be subtracted from the horizontal length allowance when using a 90° elbow
Example A: With a total rise of 6’6”/2.0 m and one horizontal 90° elbow, a total run of 13’2”/4.0 m is allowed.
Example B: If the rise is 8’2”/2.5 m then the run can be no longer than 14’10”/4.5 m.
Example C: If the run is 16’5”/5.0 m then the rise must be at least 9’10”/3.0 m.
