Vent terminals must terminate at least 3 feet (0.9 m) above any forced air inlet located within 10 feet

(3.1 m). This provision does not apply to:

1.The combustion air intake of a direct vent appliance or the circulating air inlet and flue gas discharge of listed outdoor appliances.

2.The exhaust vent terminal must be installed with at least 12 inches (30 cm) of clearance from any air opening into a building.

3.The bottom of the exhaust vent and combustion air intake terminals must be located at least 12 inches (30 cm) above grade and above the anticipated snow level.

4.Must be installed at least 3 feet (0.9 m) from any gas meter, gas valve or other gas regulating equipment.

5.Must be installed in a location where it will not be blocked by snow.

EXCEPTIONS FOR INSTALLATIONS

The vent terminal must not terminate:

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

2.Less than 7 feet (2.1 m) above a paved sidewalk or a paved driveway located on public property;

3.Above a gas meter/regulator assembly within 3 feet (0.9 m) horizontally of the vertical centerline of the regulator;

4.Within 6 feet (1.8m) of any gas service regulator vent outlet;

5.Less than 1 foot (30.5 cm) above grade level and the anticipated snow level;

6.Within 12 inches (30.5 cm) of a window or door, which can be opened in any building, any non- mechanical air supply inlet to any building, or the combustion air inlet of any other appliance;

7.Underneath a veranda, porch or deck, unless:

•The veranda, porch or deck is fully open on a minimum of two sides beneath the floor and

•The distance between the top of the vent termination and the underside of the veranda, porch or deck is greater than 1 foot (30.5 cm).

The vent system must terminate so that proper clearances are maintained as cited in local codes or the latest edition of the National Fuel Gas Code, ANSI Z223.1.73.4e and 7.8a, b as follows:

1.Do not terminate the exhaust vent terminal over public area where condensate or vapor can cause nuisance or hazard.

2.For direct vent, the venting system shall terminate at least 1 foot (0.3 m) below, 1 foot (0.3 m) horizontally from or 1 foot (0.3 m) above any door, window, or gravity air inlet into building.

3.The manufacturer also recommends the vent system terminations not be installed closer than 1 foot (0.3 m) from an inside corner of an L shaped structure.

4.The horizontal distance between two vent terminals on the same wall shall be 1 foot (0.3 m), while the vertical distance between two terminals on the same wall shall be 5 feet (1.52 m).

5.The distance between two facing vent terminals shall be 4 feet (1.22 m)

6.The vent termination shall not be mounted directly above or within 3 (0.9 m) feet horizontally from an oil tank vent or gas meter to avoid potential freeze-up from condensation.

7.The vent shall terminate a minimum of 12 inches (30.5 cm) above expected snowfall level to prevent blockage of vent termination.

Vent pipes serving power vented appliances are classified by building codes as “vent connectors”. Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATION OF WATER HEATER and CLEARANCES, and with National Fuel Gas Code and local codes.

IGI-180C, IGI-180R specifications

Bradford-White Corporation is a well-known name in the water heating industry, offering a range of reliable and efficient products. Among its noteworthy offerings are the IGI-180R and IGI-180C indirect water heaters. These models exemplify the company's commitment to quality and innovation, featuring robust designs and cutting-edge technologies.

The IGI-180R and IGI-180C units are designed to provide a consistent supply of hot water for residential and commercial applications. Both models have a storage capacity of 180 gallons, making them ideal for settings that require large volumes of hot water, such as restaurants, schools, and larger households. Their large tanks ensure minimal wait times and a reliable hot water supply, even during peak usage periods.

One of the key features of the IGI series is their indirect heating capability. Instead of relying on electric elements or gas burners, these heaters use a separate boiler or heating system to provide the necessary heat. This allows for more efficient operation, as the water is heated more evenly and effectively. The models integrate seamlessly with existing boiler systems, making them an excellent choice for those looking to upgrade or expand their hot water capabilities without extensive modifications.

Both the IGI-180R and IGI-180C incorporate advanced insulation technology, minimizing heat loss and improving energy efficiency. The high-density foam insulation encases the tank, keeping the water hot for longer periods and reducing energy costs associated with reheating. This insulation also contributes to a longer lifespan for the unit, as it reduces the wear and tear on the heating systems.

Another pivotal characteristic of these units is their durable construction. Bradford-White utilizes high-quality materials and rigorous manufacturing standards, ensuring that the IGI models withstand the test of time. The tanks are constructed from heavy-duty steel with a glass lining that protects against corrosion and sediment buildup, enhancing the longevity and performance of the water heater.

Lastly, both models come equipped with a range of safety features, including an integrated Pressure Relief Valve and a temperature control system. These elements safeguard against overheating and pressure issues, ensuring safe operation.

In conclusion, the IGI-180R and IGI-180C indirect water heaters by Bradford-White Corporation stand out for their efficient, reliable, and durable design. With advanced heating technology, excellent insulation, and robust safety features, they are a smart investment for any hot water demand scenario.
