c.Remove air baffle from 1%z” x2" flexible coupling and clean air baffle if necessary. Refer to repair parts diagram, mixer and pressure switch assembly.

d.Confirm that manual gas valve is closed and disconnect gas line to gas valve at union. Disconnect wires to gas valve. and igniter.

e.Loosen but do not remove five (5) nuts attaching mixer assembly to boiler. Remove two (2) igniter screws and very carefully remove the igniter. Use care when removing the igniter, it is very brittle!!

f.Remove five (5) nuts and remove mixer assembly. Remove burner and mixer gasket.

g.Aluminum oxide deposits are water soluble and may be rinsed away with spraying or running water. Before rinsing, connect a ‘/z” I.D. hose to the barbed fitting on the bottom of the boiler and run the hose to a bucket or drain.

h.After rinsing, remove any remaining loosened sediment using a shop vacuum with a snorkel attachment.

iInspect burner for any foreign matter in the flame ports or inside the burner. Any for- eign matter should be removed by blowing with compressed air or vacuuming.

j.Inspect interior of mixer for any signs of sediment or aluminum oxide and clean if necessary.

k.Reinstall burner and mixer gasket and position mixer assembly over studs. Install five

(5)nuts but do not tighten. Reinstall igniter and igniter gasket and fasten with two (2) screws. Use care when installing the igniter. It is very brittle!! Tighten five (5) nuts holding mixer assembly.

l.Connect:

•gas line to gas valve

•condensate drain line to boiler

•pressure switch hose to gas valve

•air by-pass to mixer

•1 1/2" x2" flexible coupling to air inlet and make sure to put air baffle back to correct position

•igniter wires

•gas valve wires

3.Visually inspect condensate lines leading from the boiler sections and the vent tee to the condensate trap. Refer to repair parts diagrams. Any foreign material or debris that is visible in the condensate lines needs to be cleaned out as follows: .

a.Raise condensate trap and drain condensate lines completely.

b.Once the condensate trap is emptied of water, disconnect condensate lines from the fittings on the boiler, the vent tee, and the condensate outlet.

c.Remove the condensate trap and run cold water through the condensate lines to thoroughly flush out any sediment or debris in the lines.

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.
