Installation of Standard Horizontal Terminals

FIGURE 1.19: INSTALLATION OF STANDARD HORIZONTAL TERMINALS

2.Assemble the vent system, starting at the boiler:

a.The CPVC elbow and the 30” straight section of CPVC provided with the kit must be used before transitioning to PVC. If necessary, the 30” straight section of CPVC may be cut at any location and the CPVC elbow inserted between the two resulting segments.

b.When cutting CPVC or PVC pipe, use a miter saw or a saw designed to cut PVC pipe. Use a miter box or other method to cut pipe squarely. De-burr both the inside and outside of the cut end.

c.Dry fit all vent components before assembly.

d.Lubricate the gasket in the vent adaptor with water. Insert the first straight section of CPVC into the vent adaptor and tighten the hose clamp.

e.Clean all CPVC and PVC components with the appropriate primer before cementing. Cement the vent system together, starting at the boiler and following the instructions provided on the cans of cement and primer. Use the cement provided with the kit to assemble all CPVC components and to make all connections between CPVC and PVC components. If additional cement/primer is needed, use cement/ primer that are designed for use with the plastics being joined (CPVC and/or PVC).

f.Depending on the layout of the vent system, the first piece of PVC vent will be connected to either the

CPVC elbow or the end of a section of CPVC pipe. In the latter case, use a PVC coupling to connect the first piece of PVC to the last section of CPVC.

g.Assemble the rest of the vent system, being sure to pitch horizontal sections back towards the boiler 1/4”/ft. Support the vent at intervals not exceeding 4ft.

h.Maintain the clearances from the vent pipe outlined in Part A of this manual. If exiting the exterior wall using PVC pipe, use half of an appropriately sized wall thimble (or a sheet metal plate) on the exterior of the building, to provide a weather tight seal while maintaining the proper clearance in the wall penetration. Seal the joint between the pipe and the wall plate using RTV applied on the exterior side of the wall. This sealant must not restrain the expansion of the vent pipe.

3.Installation of Air intake System - Start assembly of the air intake system at the boiler. Assembly of the air intake system is done in the same manner as the vent system except as follows:

a.The first piece of air intake pipe on the BWC150 and BWC 225 is installed over the intake adaptor installed in Step (1i). This piece of pipe is secured to the adaptor using at least one sheet metal screw (drill a clearance hole in the PVC intake pipe). Seal the joint between the intake pipe and the adaptor with RTV.

b.All intake piping may be PVC.

c.There is a 0” minimum clearance between the air intake piping and all types of construction.

d.To the extent possible, pitch horizontal air intake piping towards the outside .

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. With their modulating burners, durable heat exchangers, compact design, and safety features, these boilers are an excellent choice for anyone looking to invest in a reliable heating solution.
