Venting

Requirements for Terminating the Venting WARNING: Venting terminals must not be recessed into a wall or siding.

NOTE: Only approved pellet vent pipe, wall pass- throughs, and fire stops should be used when venting through combustible materials.

NOTE: Always take into consideration the effects of the prevailing wind direction or other wind currents that may cause flyash and/or smoke when placing the termination of the vent.

In addition, the following must be observed:

A. The clearance above grade must be a minimum of 18".1

B. The clearance to a window or door that may be opened must be a minimum of 48" to the side, 48" below the window/door, and 12" above the window/door.1 (with

outside air installed, 18” to the side or below)

C. A 12" clearance to a permanently closed window is recommended to prevent condensation on the win- dow.

D. The vertical clearance to a ventilated soffit located above the terminal within a horizontal distance of 2 feet (60 cm) from the center-line of the terminal must be a minimum of 18".

E. The clearance to an unventilated soffit must be a minimum of 12".

F. The clearance to an outside corner is 11" from center of pipe.

G. The clearance to an inside corner is 12".

H.A vent must not be installed within 3 feet (90 cm) above a gas meter/regulator assembly when measured from the horizontal center-line of the regulator.1

I. The clearance to service regulator vent outlet must be a minimum of 6 feet.1

J. The clearance to a non-mechanical air supply inlet to the building or the combustion air inlet to any other appliance must be a minimum of 48”.1

K. The clearance to a mechanical air supply inlet must be a minimum of 10 feet.1

(with outside air installed, 6 feet )

L. The clearance above a paved sidewalk or a paved driveway located on public property must be a minimum of 7 feet.1,2

M. The clearance under a veranda, porch, deck or balcony must be a minimum of 12 inches.1,3 (B. also applies)

NOTE: The clearance to vegetation and other exterior combustibles such as mulch is 36” as measured from the center of the outlet or cap. This 36” radius continues to grade or a minimum of 7 feet below the outlet.

1Certain Canadian and/or Local codes or regulations may require different clearances.

2A vent shall not terminate directly above a side- walk or paved driveway which is located between two single  family dwellings and serves both dwellings.

3Only permitted if veranda, porch, deck, or balcony is fully open on a minimum of 2 sides beneath the floor.

NOTE: Where passage through a wall, or partition of combustible construction is desired, the installation shall conform to CAN/CSA-B365. (if in Canada)
