c.In older system, obviously discolored, murky, or dirty water, or a pH reading below 7, are indications that the system should be cleaned.

d.A pH reading between 7 and 8 is preferred.

3.Antifreeze if needed, must be of a type specifically designed for use in closed hydronic heating systems and with aluminum.

a.Choice and use of antifreeze must be in accordance with local plumbing codes.

bOnly INTERCOOL NFP-50 is approved for use.

￿Use of any antifreeze other than INTERCOOL NFP-50 will void warranty.

￿Antifreeze must be maintained per manufacturers specifications, failure to do so will result in the warranty being voided.

c.Do not use automotive antifreeze as the type of corrosion inhibitors used will coat the boiler’s heat transfer surfaces and greatly reduce capacity and efficiency.

d.Consult antifreeze manufacturer’s literature for compatibility of antifreeze with aluminum boiler. For approved manufactured antifreeze (INTERCOOL NFP-50 Coolant) please contact Interstate Chemical Co. New York Customer Service at 1-800-422-2436. Some brands have corrosion inhibitors that break down more rapidly or become ineffective at higher operating temperatures when used with aluminum. Follow the antifreeze manufacturers instructions on determining the proper ratio of antifreeze to water for the expected low temperature conditions, and for maintaining the quality of the antifreeze solutions from year to year.

e.Use of antifreeze in any boiler will reduce capacity by as much as 10 to 20%, due to differing heat transfer and pumping characteristics. This must be taken into consideration when sizing the heating system, pump(s), and expansion tank. Consult antifreeze manufacturer’s literature for specific information on reduced capacity.

f.Water content of the boiler is 2.6 gallons. (10 liters)

B.FILLING BOILER WITH WATER AND PURGING ARE FOR SYSTEMS WITH DIAPHRAGM TYPE EXPANSION TANKS.

Refer to appropriate “Near Boiler Piping” diagrams.

1.Close all zone service valves on the supply and return piping. Open the feed valve and fill boiler with water. Make sure air vent is open. Hold relief valve open until water runs air free for five seconds to rapidly bleed air from boiler, then let the relief valve snap shut.

2.Open the zone service valve on the supply pipe for the first zone. Open the purge valve on the first zone. Feed water will fill the zone, pushing air out the purge valve. Close the purge valve when the water runs air free. Close the zone service valve.

3.Repeat step 2 for all remaining zones.

4.Open all service valves. Any air remaining trapped in the return lines between the service valves and the boiler will be pushed towards the air vent when the boiler is placed in operation.

5.Inspect piping system. Repair any leaks immediately.

C.FILLING BOILER WITH WATER AND PURGING AIR FOR SYSTEMS WITH CONVENTIONAL CLOSED TYPE EXPANSION TANKS

Refer to appropriate “Near Boiler Piping” diagrams.

1.Close all zone service valves on the supply and return piping and close the expansion tank service valve. Drain expansion tank. Open the feed valve and fill boiler with water. Hold relief valve open until water runs air free for five seconds to rapidly bleed air from boiler, then let the relief valve snap shut.

2.Open the zone service valve on the supply pipe for the first zone. Open the purge valve on the first zone. Feed water will fill the zone, pushing air out the purge valve. Close the purge valve when the water runs air free. Close the zone service valve.

3.Repeat step 2 for all remaining zones.

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.
