In Canada construct all combustion air and vent pipes for this unit of CSA or ULC certified schedule-40 CPVC, schedule-40 PVC, PVC-DWV or ABS-DWV pipe and pipe cement. SDR pipe is NOT approved in Canada.

3.Combustion air and vent piping connections on boiler are sized for 2" pipe. Any pipe size change (to 3") must be made outside of the boiler casing in a vertical run of pipe to allow for proper drainage of vent condensate. Due to potential for flue gas temperatures over 155°F, the first five (5) feet of vent pipe must be CPVC, the remaining vent pipe can be PVC. If any elbows are employed within the first 5 feet of vent, they must be CPVC too. Two (2) - 30" pieces of 2" CPVC pipe are furnished with the boiler.

NOTE: The transition from 2" pipe to 3" pipe must be made in a vertical run.

The first 5 feet of “TOTAL EQUIVALENT LENGTH” of vent piping run must be CPVC:

The length of pipe is counted from the boiler jacket (air intake pipe) or from vent tee (vent pipe).For additional elbows, reduce the maximum vent length as shown:

2" 90 degree elbow -1 ½ feet per additional elbow. 3" 90 degree elbow - 3 feet per additional elbow.

Example: To add 2 additional 90 degree elbows to a 3" pipe for a 75 boiler. Each elbow is 3 additional feet per 90 degree elbow for a total of 6 feet. (1 elbow @ 3 feet + 1 elbow @ 3 feet = 6 additional feet of pipe) The total additional pipe is then subtracted from the maximum allowable pipe length to give the new maximum length of 94 feet with 6, 90 degree elbows. (“TOTAL EQUIVALENT LENGTH”: Original 100 feet max. - 6 feet for 2 additional elbows = new 94 feet maximum length).

5.Combustion air and vent piping to be pitched back to boiler at minimum ¼” per foot from intake and vent terminals so that all moisture in combustion air and vent piping drains to boiler. Pipes must be pitched continuously with no sags or low spots where moisture can accumulate and block the flow of air or flue gas. Combustion air and vent pipes must be airtight and watertight.

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.
