to either of the unused brass screws on the service switch. Connect the white (neutral) lead from the power supply to the white screw on the service switch. Connect the green (ground) lead from the power supply to the ground (green) screw on the service switch. The receptacle on the service switch is always powered regardless of whether the switch is on or off, and could be used as a power supply for an external condensate pump if one is used.

The boiler, when installed, must be electrically grounded in accordance with the requirements of the authority having jurisdiction or, in the absence of such requirements, with the National Elec- trical Code, ANSI/NFPA-70, latest revision. In Canada, electrical wiring shall comply with the Canadian Electrical Codes, CSA-C22.1 and .2.

Run a 14 gauge or heavier copper wire from the boiler to a grounded connection in the service panel or a properly driven and electrically grounded ground rod.

B. INSTALL YOUR THERMOSTAT

The thermostat location has an important effect on the operation of your boiler system. BE

SURE TO FOLLOW THE INSTRUCTIONS INCLUDED WITH YOUR THERMOSTAT.

Locate the thermostat about five feet above the floor on an inside wall. It may be mounted di- rectly on the wall or on a vertical mounted outlet box. It should be sensing average room tem- perature. Avoid the Following:

DEAD SPOTS:

COLD SPOTS:

HOT SPOTS:

 

Behind doors

Concealed pipes or ducts

Concealed pipes

Lamps

Comers and alcoves

Stairwells - drafts

Fireplace

Direct sunlight

 

Unheated rooms on

TV sets

Kitchens

 

other side of wall

Radios

 

Set heat anticipator at 0.7 amps. Connect 24 volt thermostat leads to the two(2) yellow wires located in service switch junction box, located on outer jacket of boiler. See Fig.13 for service switch junction box and thermostat field wiring connections.

C. Connect Circulator Pump Wiring

See Fig.13 for service switch junction box and circulator pump field wiring connections. A 5 feet wiring harness with flexible metal conduit is supplied to connect the circulator pump to the ser- vice switch junction box. If the two 120 volt circulator wire terminals inside the junction box are not used, please leave the two wire nuts to prevent the short circuit.

CAUTION

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.

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.
