IX Fuel Line Piping

Fuel line piping design, materials and construction must be in accordance with local building codes, requirements of the local authority having jurisdiction, and, the latest edition of Installation of Oil-Burning Equipment (ANSI/NFPA 31). Refer also to the instruction manuals provided with the burner and oil pump.

Depending on the location of the fuel oil storage tank in relation to an oil burner, there are four types of oil piping systems generally being used:

a)ONE-PIPE GRAVITY SYSTEM - used when a fuel oil storage tank is positioned above an oil burner fuel pump. See Figure 15. A vertical distance from top of the tank to center line of the pump (Dimension ‘H’) over 8 feet will result in a pump inlet pressure in excess of the 3-psi limit in NFPA-31.

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.
