B.INSTALLATION

1.Attach combustion air intake piping to supplied Fernco 2" coupling on mixer. Attach vent piping to furnished 2" CPVC vent tee on draft inducer outlet.

NOTE: All pipe joints are to be water tight.

2.Working from the boiler to the outside, cut pipe to required length(s).

3.Deburr inside and outside of pipe.

4.Chamfer outside edge of pipe for better distribution of primer and cement.

5.Clean and dry all surfaces to be joined.

6.Check dry fit of pipe and mark insertion depth on pipe.

NOTE: It is recommended that all pipes be cut, prepared, and pre-assembled before permanently cementing any joint.

7.After pipes have been cut and pre-assembled, apply cement primer to pipe fitting socket and end of pipe to insertion mark. Quickly apply approved cement to end of pipe and fitting socket (over primer). Apply cement in light, uniform coat on the inside of socket to prevent buildup of excess cement. Apply second coat.

8.While cement is still wet, insert pipe into socket with a’/a turn twist. Be sure pipe is fully inserted into fitting socket.

9.Wipe excess cement from joint. A continuous bead of cement will be visible around perimeter of a properly made joint.

10.Handle pipe joint carefully until cement sets.

11.Support combustion air and vent piping a minimum of every 5 feet using pre-formed metal hanging straps. Do not rigidly support pipes. Allow movement due to expansion and contraction.

12.Slope combustion air and vent pipes toward boiler a minimum of 1/4" per linear foot with no sags between hangers.

13.Use appropriate methods to seal openings where vent and combustion air pipes pass through roof or side wall.

GAS SUPPLY PIPING

A. CHECK GAS SUPPLY

The gas pipe to your boiler must be the correct size for the length of run and for the total BTU per hour input of all gas utilization equipment connected to it. See Table 3 for the proper size. Be sure your gas line complies with local codes and gas company requirements.

The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ‘/z psig (3.5kpa).

The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ‘/z psig (3.50ka).

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.
