•If possible, install the vent and air intake terminals on a wall away from the prevailing wind. Reliable operation of this boiler cannot be guaranteed if the terminal is subjected to winds in excess of 40 mph.

•Air intake terminal must not terminate in areas that might contain combustion air contaminates, such as near swimming pools. See Section IV for more information on possible contaminates.

6)Permitted Terminals for Vertical Venting (Vent Options 6, 7) - A rodent screen is installed in the end of the vent pipe. Vent manufacturer part numbers for these screens are shown in Table 4. The air inlet terminal consists of a 180 degree elbow (or two 90 degree elbows) with a rodent screen as shown in Figure 6.4.

7)Vertical Vent Terminal Locations (Vent Options 6,7) - Observe the following limitations on the location of all vertical vent terminals (see Figure 6.4):

•The top of the vent pipe must be at least 2 feet above any object located within 10 feet.

•The vertical distance between top of the vent and air inlet terminal openings must be at least 12”.

•The bottom of the air inlet terminal must be at least 12” above the normal snow accumulation that can be expected on the roof.

•The air intake terminal must be located on the roof and must be no further than 24” horizontally from the exhaust pipe.

8)Wall thimbles – Wall thimbles are required where the vent pipe passes through combustible walls with less than the required clearance shown in Table 4.2 or as required by local codes. Vent manufacturer’s wall thimble part numbers are shown in Table 6.5.

9)Pitch of Horizontal piping – All horizontal vent piping must be pitched ¼” per foot so that any condensate which forms in this piping will run towards the boiler.

10)Vertical and horizontal sections of piping must be properly supported. See vent system manufacturer’s instructions for more information.

11)Fire Stops – Use fire stops where required by code or by the vent system manufacturer. Consult vent system manufacturer’s literature for information on suitable fire stops.

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.
