Crown Boiler BWC225, BWC150 specs

6. Horizontal Vent and Air Intake Terminal Location - Observe the following limitations on the vent terminal location (also see Figure 1.9). When locating a concentric terminal, observe the limitations outlined below for “vent terminals”.

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

• For Tee terminals, maintain the correct clearance and orientation between the vent and air intake terminal. The vent and air intake terminals must be at the same height and their center lines must be between 12 and 36 inches apart. Both terminals must be located on the same wall.

• The bottom of all terminals must be at least 12” above the normal snow line. In no case should they be less than 12” above grade level.

• The bottom of the vent terminal must be at least 7 feet above a public walkway.

• Do not install the vent terminal directly over windows or doors.

• The bottom of the vent terminal must be at least 3 feet above any forced air inlet located within 10 feet.

• USA Only: A clearance of at least 4 feet horizontally must be maintained between the vent terminal and gas meters, electric meters, regulators, and relief equipment. Do not install vent terminal over this equipment. In Canada, refer to B149.1 Installation Code for clearance to meters, regulators and relief equipment.

• Do not locate the vent terminal under decks or similar structures.

• Top of vent terminal must be at least 5 feet below eves, soffits, or overhangs. Maximum depth of overhang is 3 ft.

• Vent terminal must be at least 6 feet from an inside corner.

• Under certain conditions, water in the flue gas may condense, and possibly freeze, on objects around the vent terminal including on the structure itself. If these objects are subject to damage by flue gas condensate, they should be moved or protected.

• 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 these terminals are 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 the installation manual for more information on possible contaminates.

7. Permitted Terminals for Vertical Venting - Use either of the following terminals:

a. Coupling On Vent, 180 Bend On Inlet - A coupling is installed in the end of the vent pipe. Install a rodent screen between this coupling and the last piece of vent piping. Use a 180 bend or two 90 elbows to make the inlet termination (Figures 1.14, 1.16). Rodent screens are provided with the CPVC/PVC vent kit. The elbow/s and coupling must be procured locally.

b. Crown Concentric Terminal (PN 230873) - This optional terminal may be used in place of the coupling and 180 bend on the BWC070, 090, 120, and 151 (Figure 1.15). It may not be used on the BWC150 or BWC225.

8. Vertical Vent Terminal Locations (Vent Options 5,6) - Observe the following limitations on the location of all vertical vent terminals (see Figures 1.14 - 1.16):

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

• For Coupling/Elbow terminations, 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.

• For Coupling/Elbow terminations, the air intake terminal must be located on the roof and must be no further than 24” horizontally from the exhaust pipe.

9. Clearances to Combustibles - Maintain the following clearances from the vent system to combustible construction:

• Vent - 1” (also observe clearances through both combustible and non-combustible walls - see 10 below)

• Air Intake - 0”

• Concentric Portion of Crown 230873 Terminal - 0”

10. Running PVC Vent Pipe Inside Enclosures and Through Walls - PVC vent pipe must be installed in a manner that permits adequate air circulation around the outside of the pipe:

• Do not enclose PVC venting - Use CPVC in enclosed spaces, even if PVC is installed upstream.

• PVC venting may not be used to penetrate combustible or non-combustible walls unless all of the following conditions are met:

a. The wall pentration is at least 66 inches from the boiler as measured along the vent. b. The wall is 12” thick or less

c. An airspace of at least that shown in Figure 1.13 is maintained around the OD of the vent. If any of these conditions cannot be met, use CPVC for the wall pentetration.

BWC225, BWC150 specifications

The Crown Boiler BWC series, specifically the BWC150 and BWC225 models, are renowned for their performance and efficiency in residential and commercial heating applications. These boilers are designed to provide optimal heating while ensuring reliability and user-friendliness.

A standout feature of the BWC series is its high efficiency. Both the BWC150 and BWC225 are equipped with cutting-edge technology that maximizes energy use, effectively reducing operating costs. Their design utilizes a modulating burner, which adjusts the heat output based on demand. This modulation not only enhances comfort levels by maintaining a steady temperature but also conserves energy, making these models eco-friendly options.

The BWC series incorporates a durable cast-iron heat exchanger, known for its longevity and excellent heat transfer capabilities. This feature ensures that the boilers can withstand the rigors of daily operation while delivering consistent performance over time. Furthermore, the built-in control systems allow for precise monitoring and adjustment, ensuring that users have access to real-time information about their heating systems.

Another notable characteristic is the compact design of these boilers. The BWC150 and BWC225 fit seamlessly into various spaces, making them ideal for both new installations and replacements in existing systems. The straightforward installation process is a significant advantage for contractors and homeowners alike, saving time and resources.

Moreover, safety is a priority in the design of the BWC series. Each model includes multiple safety features, including low water cut-off, high-temperature limit control, and pressure relief valves. These features not only protect the boiler itself but also ensure the safety of the home or building in which it operates.

The Crown Boiler BWC series also boasts compatibility with various heating systems, including hot water baseboard, radiators, and in-floor heating, providing versatility to meet different heating needs. Its user-friendly interface and control options make it accessible to users, whether they are tech-savvy or not.

In conclusion, the Crown Boiler BWC150 and BWC225 models offer a combination of energy efficiency, robust construction, and advanced technology.
