*Unconfined area: A space whose volume is not less than 50 cubic feet per

1000 BTU per hour of all appliances installed in that space (cubic feet of space = height x

width x length).

** Confined area: A space whose volume is less than 50 cubic feet per 1000 BTU per hour of all appliances installed in that space (cubic feet of space = height x width x length).

1.Ventilation of the boiler room must be adequate to provide sufficient air to properly support combustion per the latest revision of the National Fuel Gas Code, ANSI Z223.1 section 5.3.

2.When a boiler is located in an unconfined space in a building or conventional construction frame, masonry or metal building, infiltration normally is adequate to provide air for combustion and ventilation. However, if the equipment is located in a building of unusually tight construction (See the national Fuel Gas Code, Ansi Z223.1 section 1.7), the boiler area should be considered as a confined space. In this case air for combustion and ventilation shall be provided according to part 5 on page 5. If there is any doubt, install air supply provisions in accordance with the latest revision of the National Fuel Gas Code.

Gas-fired Boiler specifications

The Utica Gas-fired Boiler is a highly efficient heating solution designed for residential and commercial applications. Recognized for its reliability and durability, the Utica Gas-fired Boiler utilizes gas as a clean energy source, which not only reduces emissions but also lowers operational costs. With various models available, this boiler caters to a wide range of heating needs, making it a versatile choice for different environments.

One of the main features of the Utica Gas-fired Boiler is its impressive energy efficiency. Many models are equipped with advanced combustion technology that ensures optimal fuel utilization, resulting in lower gas consumption and environmental impact. This efficiency is often reflected in high AFUE (Annual Fuel Utilization Efficiency) ratings, confirming the boiler's ability to convert a significant portion of fuel into usable heat.

The Utica Gas-fired Boiler employs a diversified product line, which includes both steam and hot water boiler systems. This flexibility allows users to choose the system that best suits their heating requirements. Additionally, the boilers are designed with user-friendly controls that facilitate easy operation and maintenance.

In terms of technology, Utica integrates multiple innovative features into their gas-fired boilers. The use of a modulating gas valve enables the boiler to adjust its output to match the heating demand, promoting energy efficiency and comfort. Many models also utilize a sealed combustion design that pulls in outside air for combustion, enhancing safety and improving performance in tightly sealed homes.

Moreover, the construction of Utica Gas-fired Boilers emphasizes durability. They are built from high-quality materials like cast iron or stainless steel, ensuring a long lifespan and resistance to corrosion. The robust design also facilitates easy servicing, with accessible components that minimize downtime in the event of maintenance or repairs.

Safety is another critical aspect of the Utica Gas-fired Boiler design. Features such as built-in safety controls, pressure relief valves, and flame rollout switches contribute to a safer operating environment.

In conclusion, the Utica Gas-fired Boiler exemplifies an exceptional heating solution characterized by efficiency, flexibility, and durability. With advanced technologies and a strong commitment to safety, it remains a preferred choice for those seeking reliable heating options for their spaces. The combination of low emissions, high performance, and user-friendly operation makes it ideal for modern heating applications.
