4.Tankless Heater Ratings based on I=W=H test standard.

IIIBefore Installing

1)Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with this manual and the requirements of the authority having jurisdiction.

In the absence of an authority having jurisdiction, installation must be in accordance with this manual and the latest edition of Installation of Oil Burning Equipment (ANSI/NFPA31).

Where required by the authority having jurisdiction, this installation must conform to the latest edition of Standard for Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).

2)Make sure that a properly sized chimney is available which is in good condition. Consult the authority having jurisdiction, Part VI of this manual, and ANSI/NFPA31 for additional information on venting requirements.

Power (“Side Wall”) Venting - Important Note

Two problems arise when any oil-fired appliance is power vented:

1.There is sometimes an accelerated rate of soot buildup on the oil burner cad-cell, spinner etc.

2.There is a potential for severe damage to the side of the structure in the event that the boiler operates at a high smoke level. This can happen for many reasons, some of which are out of the control of both the installer and appliance manufacturer.

Crown Boiler Company recommends the use of a chimney to vent the TWZ series boilers. If a power venter must be used, it is the responsibility of the installer and power vent manufacturer to “engineer” the power vent system. CROWN

BOILER COMPANY WILL ASSUME NO RESPONSIBILITY FOR DAMAGE TO SIDING, ETC. FROM A POWER VENTED OIL-FIRED BOILER. THIS APPLIES REGARDLESS OF THE CAUSE OF THE SOOTING.

TWZ150, TWZ125, TWZ065, TWZ075, TWZ100 specifications

Crown Boiler, known for its solid and reliable heating solutions, has designed the TWZ series to provide effective heating for both residential and commercial applications. The models in this series—TWZ090, TWZ120, TWZ175, TWZ200, and TWZ100—offer varying capacities and features tailored to meet diverse heating needs.

One of the key features of the TWZ series is its efficiency. These boilers are designed with a cast-iron heat exchanger that maximizes thermal efficiency, allowing for optimal heat transfer. This not only helps in reducing energy consumption but also ensures that the home remains warm and comfortable during the colder months. With an annual fuel utilization efficiency (AFUE) rating that can reach up to 85%, users can expect lower energy bills as well.

Each model in the TWZ series is equipped with a durable and robust construction. The cast iron sections provide increased resistance to wear and tear, making the TWZ series a long-lasting solution for heating needs. This is particularly beneficial for users looking for reliability over time, as the longevity of these boilers reduces the need for frequent replacements.

In terms of technology, the TWZ series features advanced controls that enhance functionality and ease of use. These boilers are compatible with various heating control systems, allowing users to fine-tune their heating setup according to their specific requirements. The inclusion of a flame safeguard system further ensures safety during operation, reducing the risk of malfunctions and improving overall reliability.

The TWZ series is designed for easy installation and maintenance. With options for direct venting or conventional chimney venting, homeowners and installers can choose the most suitable configuration for their properties. Additionally, the maintenance access points on these boilers make routine service checks simple and efficient, ensuring that the boilers remain in optimal condition.

Another important characteristic of the Crown Boiler TWZ series is its quiet operation. Advanced engineering minimizes noise production, making these boilers ideal for residential settings where peace and comfort are valuable.

In conclusion, the Crown Boiler TWZ090, TWZ120, TWZ175, TWZ200, and TWZ100 models offer a compelling combination of efficiency, durability, advanced technology, and user-friendly features. Whether for residential or light commercial use, they represent an excellent choice for anyone seeking reliable heating solutions.
