The burners and pilot should be checked for signs of corrosion, rust or scale buildup. The area around the boiler must be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids.

The free flow of combustion and ventilating air to the boiler and boiler room must not be restricted or blocked.

It is recommended that a qualified service agency be employed to make an annual inspection of the boiler and heating system. They are experienced in making the inspections outlined above, and, in the event repairs or corrections are necessary, trained technicians can make the proper changes for safe operation of the boiler.

CHECKING GAS INPUT RATE TO BOILER

Gas input to the boiler can be adjusted by removing the protective cap on the pressure regulator, (See figures 14, 15, & 16 on pages 14 & 15), and turning the screw clockwise to increase input and counterclockwise to decrease input. Natural gas manifold pressure should be set at approximately 3.5 inches water column. Propane gas manifold pressure should be set at approximately 11.0 inches water column. These manifold pressures are taken at the outlet side of the gas valve. See figures15 & 17 on pages14 &

15.To check for proper flow of natural gas to the boiler, divide the input rate shown on the rating plate by the heating value of the gas obtained from the local gas company. This will determine the number of cubic feet of gas required per hour. With all other gas appliances off, determine the flow of gas through the meter for two minutes and multiply by 30 to get the hourly rate. Make minor adjustments to the gas input as described above.

Burner orifices should be changed if the final manifold pressure varies more than plus or minus 0.3 inches water column from the specified pressure.

Primary air adjustment is not necessary, therefore air shutters are not furnished as standard equipment. Air shutters can be furnished on request where required by local codes or conditions.

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.
