8.Locate and guard vent termination to prevent acci- dental contact by people or pets.

9.DO NOT terminate vent in window well, stairwell, alcove, courtyard or other recessed area.

10.DO NOT terminate above any door, window, or gravity air intake. Condensate can freeze, causing ice formations.

11.Locate or guard vent to prevent condensate from damaging exterior finishes. Use a rust-resistant sheet metal backing plate against brick or mason- ry surfaces.

12.DO NOT extend exposed vent pipe outside of building. Condensate could freeze and block vent pipe.

U.S. Installations

Refer to the latest edition of the National Fuel Gas Code.

Vent termination requirements are as follows:

1.Vent must terminate at least 4 ft below, 4 ft hori- zontally from or 1 ft above any door, window or gravity air inlet to the building.

2.The vent must not be less than 7 ft above grade when located adjacent to public walkways.

3.Terminate vent at least 3 ft above any forced air inlet located within 10 ft.

4.Vent must terminate at least 4 ft horizontally, and in no case above or below unless 4 ft horizontal distance is maintained, from electric meters, gas meters, regulators, and relief equipment.

5.Terminate vent at least 6 ft away from adjacent walls.

6.DO NOT terminate vent closer than 5 ft below roof overhang.

7.The vent terminal requires a 12 in. vent terminal clearance from the wall.

8.Terminate vent at least 1 ft above grade, including normal snow line.

9.Multiple direct vent installations require a 4 ft clearance between the ends of vent caps located on the same horizontal plane.

Canadian Installations

Refer to latest edition of the B149 Installation code.

A vent shall not terminate:

1.Directly above a paved sidewalk or driveway which is located between two single-family dwell- ings and serves both dwellings.

2.Less than 7 ft (2.13 m) above a paved sidewalk or paved driveway located on public property.

3.Within 6 ft (1.8 m) of a mechanical air supply inlet to any building.

4.Above a meter/regulator assembly within 3 ft (915

mm)horizontally of the vertical centre-line of the regulator.

5.Within 6 ft (1.8 m) of any gas service regulator vent outlet.

6.Less than 1 ft (305 mm) above grade level.

7.Within the 3 ft (915 mm) of a window or door which can be opened in any building, any non-mechani- cal air supply inlet to any building or the combustion air inlet of any other appliance.

8.Underneath a verandah, porch or deck, unless the verandah, porch or deck is fully open on a mini- mum of two sides beneath the floor, and the distance between the top of the vent termination and the underside of the verandah, porch or deck is greater than 1 ft (305 mm).
