GOLD CGi-4E Gas-Fired Water Boiler — Boiler Manual

3e Venting — direct exhaust — termination

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

1.Locate the boiler and vent penetration through the wall so all requirements on this page and in Fig- ure 12 will be met. Also follow vent manufacturer’s instructions.

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

3.Prevailing winds could cause freezing of condensate and water/ice buildup on vent termination, building, plants or roof. Ice buildup on vent termination can cause boiler shutdown and building freeze-up.

4.Winds over 40 mph can cause nuisance boiler shut- down if boiler is sidewall vented. This could result in loss of heat to building, causing freeze-up.

5.Locate or guard vent termination to prevent con- densate from damaging exterior surfaces.

6.Locate the vent termination well away from trees, shrubs, and decorative items.

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

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

9.Do not wrap or insulate vent pipe or fittings.

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

11.Do not connect:

Any other appliance to vent pipe.

Multiple boilers to a common vent pipe.

12.Canadian installations — See B149.1 or B149.2 Installation Code. Terminate vent no less than 6 feet from another combustion air inlet, 3 feet from any other building opening, and 3 feet from any gas service regulator.

13.See Figure 12, showing that the vent must termi- nate:

more than 4 feet below or to side of all doors or windows.

more than 1 foot above grade or anticipated snow line.

at least 7 feet above public walkway.

3 feet above any forced air intake within 10 feet.

14.Vent must also terminate:

at least 6 feet away from adjacent walls.

no closer than 5 feet below roof overhang.

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.

15.Site conditions may dictate greater clearances.

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

A gas vent extending through an exterior wall shall not terminate ad- jacent to the wall or below building extensions such as eaves, parapets, balconies or decks. Failure to com- ply could result in severe personal injury, death or substantial property damage.
