F. TEST HIGH LIMIT CONTROL AND ADJUST

While burner is operating, move indicator on high limit control below actual boiler water temperature. Burner should go off while circulator continues to operate. Raise limit setting above boiler water temperature and burner should reignite after pre purge and igniter warm- up period. Set the high limit control to the design temperature requirements of the system. Maximum high limit setting is 200°F. Minimum high limit setting is 100°F.

G. TEST OTHER SAFETY CONTROLS

If the boiler is equipped with a low water cut off, a manual reset high limit, or additional safety controls, test for operation as outlined by the control manufacturer. Burner should be operat- ing and should go off when controls are tested. When safety controls are restored, burner should reignite.

H. SET THERMOSTAT HEAT ANTICIPATOR (IF USED) AND VERIFY THERMOSTAT OPERATION For a single thermostat connected to the yellow thermostat lead wires in the furnished field wiring junction box, the heat anticipator should be set at 0.7 amps. For other wiring configura- tions, refer to the instructions provided by the thermostat manufacturer regarding adjustment of heat anticipator. Cycle boiler with thermostat. Raise the thermostat to the highest setting and verify boiler goes through normal start up cycle. Lower thermostat to lowest setting and verify boiler goes off.

I. MEASURE THE NATURAL GAS INPUT RATE

Correct input rate is essential for proper and efficient operation of the burner and boiler.

1.Determine elevation at installation site.

2.See page 4 and 5 of this manual to determine the correct input rate for the local elevation.

3.Obtain the yearly average heating value of the local gas supply from the gas utility. At sea level elevation, it should be approximately 1000 Btu’s per standard cubic foot.

4.Operate boiler for 5 minutes.

5.Turn off all other gas appliances, extinguishing standing pilots where applicable.

6.At gas meter, measure time in seconds required to use one cubic foot of gas.

7.Calculate input rate according to the following formula:

3600xheating value from step 3

Btuh input rate = time from step 6

8.Measured input rate should be within +/-2% of the input rating from step 2. If within 2%, go to step 9. If not, adjustment is required, proceed as follows:

a.Turn boiler off

b.Set up U-tube manometer or differential pressure gauge for measuring manifold pres sure, see FIG. 17.

c.Manometer or gauge must be able to read at least 0.0 to 3.0 inches water column of pressure, and resolve to at least 0.1 inches water column.

d.Turn boiler on.

e.Manifold pressure has been nominally set at 2.5 inches w.c. Manifold pressure and input rate must always be measured with pressure regulator cover screw installed. Cover screw must be removed for adjustment. Manifold pressure reading will change (increase) when cover screw is removed.

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.
