D. How to Use the Vent Graph

E. Venting Guidelines

1.Measure the vertical distance from the center line of the flue pipe to the center of the 90° elbow. On the graph below, draw a horizontal line from that measurement on the vertical axis across until it intersects with the slanted line.

2.From the point of this intersection, draw a vertical line to the bottom of the graph.

3.The point at which this line meets the bottom line of the graph is the maximum length of the horizontal run.

EXAMPLE 1: If the vertical dimension from the center line of the flue vent to the center of the 90° elbow is 7 ft. (2m), the horizontal run to the outer wall flange must not exceed 9 ft.-8 in. (3m).

EXAMPLE 2: If the vertical dimension from the center line of the flue vent is 21 ft. (6m), the horizontal run to the outer wall flange must not exceed 4 ft.-3 in. (1m).

4.Each 90° elbow is equivalent to 3 ft. (914mm) of vent pipe and each 45° elbow is equivalent to 1 ft. (305mm) of vent pipe, and must be subtracted from the vent pipe run. A single horizontal to vertical 90° elbow is already calculated into the allowable 15 ft. (5m) run. Each additional 90° elbow reduces the maximum horizontal distance by 3 ft. (914mm).

EXAMPLE: The use of 3 elbows would reduce the allowable horizontal run to 9 ft. (3 -1 = 2 elbows x 3 ft. = 6 ft.; 15 ft. max. - 6 ft. = 9 ft. max.).

NOTES

The maximum horizontal vent run is 15 ft. (5m) when the vertical vent rise is 10 ft. (3m).

Horizontal sections require a 1/4 in. (6mm) rise for every 12 in. (305mm) of horizontal travel.

Exterior Vent Diameter = 6-5/8 in. (168mm); Inner Vent Diameter = 4 in. (102mm)

Horizontal sections require noncombustible support every 3 ft. (914mm), e.g. wall straps.

For any vertical termination a minimum of 6 in. (152mm) vertical must be used.

EXCEPTIONS

FOR HORIZONTAL INSTALLATIONS:

The maximum horizontal vent run is 30 in. (762mm).

The maximum horizontal vent run with a 45° elbow is 18 in. (457mm).

No external minimum rise is required.

The minimum horizontal vent run is 6 in. (152mm).

NOTE: If your installation falls within the gray-shaded area on graph, see information on intake damper operation, on page 36.

*In the Commonwealth of Massachusetts, the word damper shall be replaced with the words flue restrictor.
