Installation & Service Manual

7Maintenance

s.Ensure that all burner ports are cleaned to remove any soot. See Inspection and Cleaning Procedure, page 46.

t.Carefully re-install the heat exchanger, “V” baffles, jacket panels, and wires.

u.Reassemble all gas and water piping. Test for gas leaks.

v.Cycle the appliance and check for proper operation.

Inspection of Heat Exchanger Waterways

Appliances operated in hard water areas should have periodic inspections of the tubes to be sure that no sediment or scale accumulates on the heat transfer surfaces. Inspection plugs are located at both ends of the heat exchanger. Inspection plugs should be removed and tubes inspected at the end of the first 45 days of operation and again at the end of 90 days of operation. If no scale accumulation is observed, inspections can be made at the end of each six months of operation.

IMPORTANT

Upon completion of any testing on the gas system, leak test all gas connections with a soap solution while main burners are operating. Immediately repair any leak found in the gas train or related components. Do Not operate an appliance with a leak in the gas train, valves or related piping.

Water Circulating Pump

Inspect pump every 6 months and oil if required. Use SAE 30 non-detergent oil or lubricant specified by pump manufacturer.

Clear Area

1.Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

2.Check frequently to be sure the flow of combustion and ventilation air to the boiler is not obstructed.

Review with owner

1.Review the User’s Information Manual with the owner.

2.Emphasize the need to perform the maintenance schedule specified in the User’s Information Manual (and in this manual as well).

3.Remind the owner of the need to call a licensed contractor should the appliance or system exhibit any unusual behavior.

4.Remind the owner to follow the proper shutdown procedure and to schedule an annual start-up at the beginning of the next heating season.

Lochinvar 45,000 - 260,000 BTU/HR Review with owner, Inspection of Heat Exchanger Waterways, Gas Train and Controls

45,000 - 260,000 BTU/HR specifications

Lochinvar, a leader in high-efficiency heating solutions, presents the Lochinvar line of boilers, specifically the Lochinvar 45,000 - 260,000 BTU/HR models. These boilers are designed to meet a wide range of heating demands, making them ideal for residential and commercial applications alike.

One of the key features of the Lochinvar boilers is their impressive efficiency rating. Utilizing advanced condensing technology, these units can achieve efficiencies of up to 96% AFUE (Annual Fuel Utilization Efficiency). This high efficiency not only reduces fuel consumption but also lowers utility bills, making it a cost-effective solution for heating needs.

The Lochinvar boilers are equipped with a powerful heat exchanger constructed from durable stainless steel. This design not only maximizes heat transfer but also enhances the longevity of the unit. By preventing corrosion and minimizing maintenance requirements, the stainless steel heat exchanger ensures that the boiler operates at peak performance for years.

Another significant aspect of the Lochinvar boilers is their modulating burner system. This technology allows the boiler to adjust its output based on demand, ensuring that it only uses the energy necessary to maintain the desired temperature. This feature not only improves efficiency but also contributes to a more comfortable indoor environment by minimizing temperature fluctuations.

The Lochinvar series also showcases a user-friendly control interface. The advanced LCD display allows for easy monitoring and adjustment of system settings. Connectivity options are often included, providing the ability to integrate with modern building management systems for enhanced control and diagnostics.

Safety features abound in the Lochinvar models, which include built-in safeguards such as temperature and pressure relief valves, flame detection systems, and modulation cut-off to protect against overheating and other hazardous conditions.

Moreover, these boilers are designed for easy installation and maintenance. Compact dimensions and lightweight design facilitate straightforward setup, even in tight spaces. Additionally, users can take advantage of the unit’s self-diagnostic capabilities to simplify troubleshooting and reduce downtime.

In conclusion, the Lochinvar 45,000 - 260,000 BTU/HR boilers represent a pinnacle of innovation in heating technology. With high efficiency, advanced control systems, durable components, and safety features, they stand out as reliable and effective solutions for a variety of heating applications, ensuring comfort and efficiency in any environment.
