XII Service and Maintenance

The following procedure should be performed on an annual basis:

1)Turn off electrical power and oil supply to the boiler.

2)Clean the boiler as follows:

a)Remove vent connector and piping.

b)Remove barometric draft regulator.

c)Remove top jacket panel to gain access to boiler flue collector.

d)Unscrew four wing nuts and remove canopy retaining carriage bolts, lift off the canopy and ceramic fiber sealing strips.

e)Unplug the burner, disconnect the oil lines (if the pump is hard piped), and remove the two 5/16” bolts securing the burner door. Open the burner swing door.

f)Thoroughly brush boiler flueways from the top and diagonally between casting pin rows. Be careful when brushing the rear passage not to damage the rear target wall insulation.

g)Vacuum soot and debris from combustion chamber.

h)Check condition of rear target wall insulation, combustion chamber liner, and burner door insulation; replace if required.

i)Check burner head for signs of deterioration. Clean the head of any deposits.

j)Close burner door, reinstall 5/16” bolts, reconnect fuel oil and electrical lines.

k)Installation of boiler canopy, jacket top panel barometric draft regulator and breeching piping is done in reverse order of removal. Make sure canopy is sealed tight to the casting; replace ceramic fiber sealing strips as needed. All vent piping joints must be flue gas leak free and secured with sheet metal screws.

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.
