The Vent Option #1 column in Table 6.2a describes a horizontal direct vent system using 3” vent pipe. From this column, we see that a BWC150 may have a vent length of up to 55ft. The first 90 elbow and the termination elbow are not considered. From Table 6.6, the equivalent length of the 3” 45 elbow is 4ft and the equivalent length of the 3” 90 degree elbow is 5.5ft. The maximum allowable run of straight pipe on this system is therefore:

55ft – 4 ft – 5.5ft = 40ft

Since the planned installation has only 14 ft of straight pipe, the planned vent length is acceptable.

3)Minimum Vent and Air Intake Lengths - Minimum vent length is 2ft. Minimum air inlet length is 2ft.

4)Permitted Terminals for Horizontal Venting (Vent Options 1,2) - The vent terminal is either a tee or an elbow supplied by the vent system manufacturer and equipped with a rodent screen. Vent system manufacturer’s part numbers for these fittings are shown in Table 6.5. In some cases, the elbows and tees shown in Table 6.5 require separate rodent screens. When this is the case, vent manufacturer part numbers for these additional parts are shown in Table 6.5 along with the termination fitting.

The air intake fitting on a horizontal vent systems is always a 90 degree elbow with a rodent screen. This elbow is made out of the same material as the rest of the air inlet system (either galvanized or PVC) and is installed as shown in Figure 6.1.

5)Horizontal Vent and Air Intake Terminal Location - Observe the following limitations on the vent terminal location (also see Figure 6.3):

•Vent terminals must be at least 1 foot from any door, window, or gravity inlet into the building.

BWC Series specifications

The Crown Boiler BWC Series is a modern choice for heating needs, renowned for its efficiency and robust design. This series offers a range of residential and light commercial heating applicabilities, ensuring both comfort and reliability for users.

One of the standout features of the BWC Series is its efficiency. Crown Boilers utilize advanced technologies to maximize energy output while minimizing fuel consumption. With an AFUE (Annual Fuel Utilization Efficiency) rating often exceeding 90%, users can expect significant cost savings on their energy bills over time.

The BWC Series employs a high-quality, stainless steel heat exchanger, which not only enhances performance but also extends the lifespan of the boiler. This heat exchanger is designed to transfer heat efficiently, ensuring that the maximum amount of energy from the fuel is converted into usable heat. Additionally, the design helps to prevent corrosion and maintain system integrity over years of usage.

For technological advancements, the BWC Series incorporates a modulating gas valve which allows for precise control over the boiler's operation. This feature enables the system to adjust its output based on the heating demands of the home, resulting in improved energy efficiency and consistent comfort levels. Moreover, this modulating technology reduces the frequency of cycling, thereby prolonging the lifespan of the unit and minimizing wear and tear.

Another characteristic of the Crown Boiler BWC Series is its user-friendly interface. The boiler is equipped with a simple control panel that allows for easy monitoring and adjustment of settings. This accessibility is essential for users who want to manage their heating system without the need for extensive technical knowledge.

In terms of installation and maintenance, the BWC Series is designed with convenience in mind. Its compact footprint allows it to fit comfortably in a variety of spaces, making it an ideal choice for homes with limited installation areas. Additionally, Crown Boiler's commitment to high manufacturing standards ensures that the units require minimal maintenance, providing peace of mind to homeowners.

Overall, the Crown Boiler BWC Series is an excellent solution for those seeking efficient, reliable heating. Its combination of advanced technology, quality construction, and user-friendly design makes it an attractive option for any residential or light commercial application. Whether replacing an old system or installing a new one, the BWC Series delivers comfort and performance that can be depended upon.
