NOTICE

The Knight Boiler Installation and Operation Manual along with the Knight Boiler Service Manual are for use only by a qualified heating installer/service technician. Refer only to this User’s Information Manual for your reference. Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury (exposure to hazardous materials) or loss of life. Installation and service must be performed by a qualified installer, service agency or the gas supplier (who must read and follow the supplied instruction before installing, servicing, or removing this boiler. This boiler contains materials that have been identified as carcinogenic, or possibly carcinogenic, to humans).

Boiler service and maintenance –

•To avoid electric shock, disconnect electrical supply before performing maintenance.

•To avoid severe burns, allow boiler to cool before performing maintenance.

Boiler operation –

• Do not block flow of combustion or ventilation air to

the boiler. This boiler is equipped with a control which

will automatically shut down the boiler should air or

vent be blocked. If vent or air blockage is easily

accessible and removable, remove it. The boiler should

attempt to restart. If blockage is not obvious or cannot

be removed, have the boiler and system checked by a

qualified service technician.

• Should overheating occur or gas supply fail to shut off,

NOTICE

￿WARNING

When calling or writing about the boiler – Please have the boiler model and serial number from the boiler rating plate.

Consider piping and installation when determining boiler location.

Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Failure to adhere to the guidelines on this page can result in severe personal injury, death, or substantial property damage.

do not turn off or disconnect electrical supply to the

circulator. Instead, shut off the gas supply at a location

external to the appliance.

• Do not use this boiler if any part has been under water.

The possible damage to a flooded appliance can be

extensive and present numerous safety hazards. Any

appliance that has been under water must be replaced.

Boiler water –

•Thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be damaged by build-up or corrosion due to sediment.

•Do not use petroleum-based cleaning or sealing compounds in the boiler system. Gaskets and seals in the system may be damaged. This can result in substantial property damage.

•Do not use “homemade cures” or “boiler patent medicines”. Serious damage to the boiler, personnel, and/or property may result.

•Continual fresh make-up water will reduce boiler life. Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by makeup water can cause internal corrosion. Leaks in boiler or piping must be repaired at once to prevent makeup water.

Freeze protection fluids –

•NEVER use automotive antifreeze. Use only inhibited propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and seals used in hydronic systems.

The Lochinvar 80 - 285 is a well-regarded series of high-efficiency boilers that has established itself as a leading option for both residential and commercial applications. Known for its robust performance and innovative technologies, this range is designed to meet the diverse heating needs of modern buildings.

One of the standout features of the Lochinvar 80 - 285 series is its advanced condensing technology. This allows the boiler to extract a greater amount of heat from the combustion gases, resulting in higher energy efficiency. With an annual fuel utilization efficiency (AFUE) rating that can exceed 95%, users can expect significant savings on energy costs while reducing their carbon footprint.

Another important characteristic of the Lochinvar 80 - 285 is its stainless steel heat exchanger. The use of stainless steel not only enhances durability but also ensures longer life expectancy and resistance to corrosion. This makes it an excellent choice for harsh environments or areas with hard water. Furthermore, the design of the heat exchanger promotes optimal thermal performance and efficient heat transfer, ensuring that the system operates at peak efficiency.

The Lochinvar 80 - 285 series also incorporates intelligent controls, allowing for enhanced operation and management of heating systems. The intuitive user interface provides easy access to critical system information, allowing users to monitor performance and make adjustments as needed. The built-in diagnostic tools help in troubleshooting and maintaining optimal performance, minimizing downtime and service costs.

Moreover, the boiler is designed with a flexible venting system. It can be vented vertically or horizontally, offering installation versatility for various building configurations. This adaptability makes it a favorite among contractors and engineers, simplifying the installation process and reducing labor costs.

The Lochinvar 80 - 285 series prioritizes safety as well. It comes equipped with multiple safety features, including flame monitoring and automatic shut-off valves, ensuring that the system operates safely under all conditions. Additionally, its low emissions design contributes to a cleaner environment by complying with stringent emission standards.

In summary, the Lochinvar 80 - 285 series stands out for its high efficiency, durability, and user-friendly technology. With its advanced condensing technology, stainless steel heat exchanger, intelligent controls, and versatile installation options, it is a dependable choice for anyone seeking a reliable heating solution that prioritizes performance and sustainability.
