VI Venting

WARNING

Failure to vent this boiler in accordance with these instructions could result in unreliable boiler operation, severe damage to the boiler or property, or unsafe operation:

*Do not attempt to vent this boiler with galvanized, PVC, or any other vent system not listed in Table 4.

*Do not attempt to mix components from different approved vent systems.

*Do not obtain combustion air from within the building.

*Do not install a barometric damper or drafthood on this boiler.

*Do not attempt to use the vent system for this boiler with any other appliance.

*Moisture and ice may form on the surfaces around the vent termination. To prevent deterioration, surfaces should be in good repair (sealed, painted, etc.)

A. Vent System Design

There are two basic ways to vent the BWC boiler:

•Horizontal (“side wall”) Venting - Vent system exits the building through an outside wall. Combustion air is obtained through a separate pipe from outside.

•Vertical Venting - Vent system exits the building through a roof. Combustion air is obtained through a separate pipe from outside.

A description of each of these venting options is listed in Tables 6.2a and 6.2b. For clarity, these vent options are numbered from 1 to 7. One of the vent option columns in Table 6.2 must match the planned vent and air intake system exactly. In addition, observe the following guidelines:

1)Approved vent systems - Use only one of the approved vent systems shown in Table 4. These systems are made of a special stainless steel alloy (AL29-4C) for protection against corrosive flue gas condensate. They are also designed to provide a gas tight seal at all joints and seams so that flue gas does not enter the building. Each approved vent system has a unique method for installation - do not attempt to mix components from different vent systems.

2)Maximum Vent and Air Intake Lengths - The maximum length of the vent air intake piping depends upon the vent option selected and the boiler size. See Table 6.2 for the maximum vent length. In addition to the maximum length of piping shown in Table 6.2, the following fittings may also be used:

•Horizontal Vent Systems: One 90 deg. elbow

•Horizontal Air Intake Systems: One 90 deg. elbow

•Vertical Vent Systems: Two 90 deg. elbows

•Vertical Air Intake Systems: Two 90 deg. elbows

If additional elbows are desired, the maximum allowable vent length must be reduced by the amount shown in Table 6.6 for each additional elbow used. Termination fittings are not counted when counting additional elbows.

Example:

A 3” vent system is planned for a horizontally vented BWC150 which has the following components:

2 ft vertical pipe

1 90 elbow

5 ft horizontal pipe

1 90 elbow

3 ft horizontal pipe

1 45 elbow

4 ft horizontal pipe

1 termination elbow

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.
