Locating The Power Venter

Calculating Equivalent Feet of a Vent System

Procedure

1.Determine the total equivalent feet for each type of fitting used in the venting system from Table 2.

2.Calculate the total feet for the straight lengths of pipe.

3.Add the equivalent feet of the fittings to the total amount of feet of straight length pipe. This will approximate the total equivalent feet of the vent system.

Example: System Pipe Size = 4"

Step 1 2-90° Elbows (4") = 14 Ft.

Step 2 10-2 Ft. Lengths of 4" Pipe = 20 Ft.

Step 3 Total Equivalent Feet = 14 Ft. + 20 Ft. = 34 Ft.

To estimate the equivalent foot length of the Reducer/Increaser chart, find the figure at the intersection of the small pipe size and the large pipe size.

Terminal Locations of a Vent System

Location of the termination of the venting system should comply with the National Fuel Gas Code, ANSI Z223.1, manufacturer’s recommendations and/or applicable local codes. See diagram for typical terminal locations.

A C F D B

A.The exit termination of a mechanical draft system must not be less than 7’ above grade when located adjacent to a public walkway.*

B.The venting systems, with the exception of direct vent appliances, must terminate at least 4’ below, 4’ horizontally, or 1’ above any door, window or gravity air inlet into the building.

C.A venting system must terminate at least 3’ above any forced air inlet located within 10’.

D.The bottom of the vent terminal must be located at least 1’ above finished grade.**

E.The vent termination should not be mounted directly above or within 3’ horizontally from an oil tank vent or gas meter (not shown in diagram).

F.The vent termination point must not be installed closer than 3’ from an inside corner of an L-shaped structure.

G.For basement installations where a window well must be used or in installations where the vent terminal cannot be mounted to maintain the minimum 12" clearance above grade, use a Field Vent Riser™. The Vent Riser ensures the vent termination is above grade or the snow line and is in compliance with local codes (not shown in diagram).

* 10" or larger should be 10’ minimum above public walkway. ** 10" or larger should be 4‘ above finished grade.
