I.Remove regulator cover screw on top of gas valve, and insert an appropriate screw- driver into adjustment screw.

II. Turn adjustment screw clockwise to increase input rate, or counter clockwise to de- crease input rate.

III.Replace cover screw, or cover hole temporarily with your finger to check new mani- fold pressure setting. Do not set manifold pressure lower than 2.0 inches w.c. or

higher than 3.0 inches w.c. when adjusting input rate.

IV. Measure new input rate (cover screw must be installed). Repeat steps I.-IV until the input rate is within +/-2% of the nameplate input rating.

V.If the actual input rate can not be set to within 2% of the correct input rating by adjust- ing manifold pressure, a change in gas orifice size is required. Consult the boiler manufacturer for information on correct orifice sizing. The specific gravity (G) and the higher heating value (HHV) of the local natural gas must be obtained from the local gas utility in order to determine the proper orifice size.

f.After adjusting input rate, turn boiler off, remove manometer or pressure gauge, reinstall 1/8" plug on gas valve. Turn boiler on.

9.Restore all gas appliances that may have been shut off (while measuring boiler input rate) to normal operating conditions.

J. SET THERMOSTAT TO DESIRED ROOM TEMPERATURE

Observe several operating cycles to verify proper operation.

GAS-FIRED BOILERS specifications

Quantum gas-fired boilers represent a significant advancement in the realm of residential and commercial heating solutions. These innovative systems efficiently utilize natural gas to deliver consistent heating, catering to a wide range of climates and applications. With rising energy costs and increasing environmental concerns, the adoption of gas-fired boilers has gained momentum, making them a popular choice for heating needs.

One of the main features of Quantum gas-fired boilers is their impressive energy efficiency. Modern gas boilers are designed to achieve high efficiencies, often ranging from 90% to 98%. This means that the majority of the energy consumed is converted into useful heat, significantly reducing fuel costs and environmental impact. Their ability to operate at such high efficiencies is largely due to advanced condensing technology, which captures and reuses the heat from exhaust gases, thus maximizing the energy extracted from the fuel.

Moreover, Quantum gas-fired boilers are equipped with advanced control systems that allow for precise temperature regulation. These systems can monitor changes in demand and adjust the operation of the boiler accordingly, ensuring that energy consumption is kept to a minimum without sacrificing comfort. This not only promotes energy savings but also extends the lifespan of the appliance.

In addition to efficiency and control, modular design is another important characteristic of Quantum gas-fired boilers. Many models are available in compact sizes, making them suitable for diverse installation environments, including tight spaces and urban areas. Their versatility allows for installation in various configurations, including wall-mounted and floor-standing units, which can be tailored to fit the specific requirements of a heating system.

Moreover, modern Quantum gas-fired boilers come with features that enhance user experience and maintenance. Many incorporate built-in diagnostic tools that indicate potential issues before they become significant problems, facilitating timely interventions and reducing downtime. Some models even offer connectivity features, enabling remote monitoring and control through smartphone applications.

In summary, Quantum gas-fired boilers deliver exceptional energy efficiency and reliability, employing advanced technologies such as condensing methods and smart controls. Their modular design and user-friendly features make them an appealing choice for anyone seeking a high-performing heating solution. As the demand for sustainable and cost-effective heating solutions continues to rise, Quantum gas-fired boilers are poised to play a crucial role in meeting the world's heating needs.
