CHECK SAFETY CONTROL CIRCUIT, after burner adjustments are made, for satisfactory operation.

1.Pilot: With main burner operating, turn the pilot gas adjusting screw clockwise until pilot gas is turned off. See figures 14, 15, & 16 on pages 14 & 15. Within 90 seconds

the main gas control should close, shutting off the gas to the main burner.

2.High limit control (figure 22 on page 19). Remove cover and note temperature setting. Decrease this setting to minimum and operate boiler. When the boiler water temperature exceeds the control temperature setting, the control will open the circuit, closing the automatic main gas valve.

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.
