Vent termination

Venting method definitions

Direct vent — Uses outside combustion air with combustion air connector piping sealed at all joints and seams. Also known as “sealed combustion”.

Non-Direct vent — Uses inside combustion air with no combustion air connector piping.

Properly locate vent termination

Follow instructions on this page when determining vent location to avoid possibility of severe personal injury, death or substantial property damage.

1.When using direct vent method — Refer to separate instructions packed with Weil-McLain direct vent termination kit and vent pipe manufacturer's instructions for additional locations.

2.For location of non-direct vent vertical termination, see vent pipe manufacturer's instructions.

3.Gases will form white plume in winter. Plume could obstruct window view.

4.Prevailing winds could cause freezing of condensate and water/ice buildup on building, plants or roof.

5.Locate or guard vent to prevent accidental contact by people or pets.

6.Do not terminate vent in window well, stairwell, alcove, courtyard, or other recessed areas.

7.Non-Direct vent installations only — Vent must terminate more than 1 foot below or to side of all doors or windows. See Figure 1.

8.Vent must terminate more than 1 foot above grade or

anticipated snow line. In addition, vent termination must be at least 7 feet above public walkway and 3 feet above any forced air intake within 10 feet. Stay well away from trees, shrubs, and decorative items. Site conditions may dictate greater clearances. See Figure 1.

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

10.Locate or guard vent to prevent condensate from damaging exterior finishes.

11.Do not extend exposed vent pipe outside of building. Condensate could freeze and block vent pipe.

12.Vent must terminate at least 6 feet away from adjacent walls.

13.Do not terminate vent closer than 5 feet below roof overhang.

14.Do not terminate vent above any door or window. Condensate can freeze, causing ice formations.

15.Do not use existing chimney as raceway if another appliance or fireplace is vented into or through chimney.

16.Do not connect:

•Any other appliance to vent pipe.

•Multiple boilers to a common vent pipe.

17.Do not wrap or insulate vent pipe and fittings.

18.Canadian installations — See CAN/CGA B149.1 or B149.2 Installation Code.
