TAKING CARE

OF YOUR BOILER

At least once each month during the heating season, perform the following inspections:

Check Vent Tubing: Look for leakage at joints and sagging of vent tubing runs. If evident, call a qualified service technician.

Check Vent Terminal (Outside): Look for and remove any obstructions (i.e. leaves, shrubs, snow).

Check Water Piping: Look for leaks around boiler and at all joints. If evident, call a qualified service technician.

Check System Water Pressure: The temperature/pres- sure gage indicates the pressure in the boiler for each water temperature. For most installations, it should indicate about 12 psi to 15 psi for 70° to 100° water temperatures and from 15 psi to 25 psi for temperatures up to 240°. Ask your installer or service technician to explain and show you what normal pressures to look for.

If pressure decreases from normal, the system is losing water; if pressure increases from normal, the boiler relief valve will open to relieve pressure (water will be evident on floor below relief valve discharge piping). In either case, call a qualified service technician.

At least once a year, check the air filter: Replace it (recommended) or clean it. For access to the filter, remove boiler front cover by pushing down on top center portion of cover until support clip releases cover at top, then lift off of support clips at bottom of cover.

Open air filter box cover by rotating the 1/4 turn fastener on top of cover, then swing open at hinge.

Slant/Fin replacement air filter, part number 65-0524, must be used. The filter can be cleaned with soap and water. Shake off excess moisture before replacing.

In the case of severe outside dust/dirt conditions which cause above-average accumulation on the filter, it may be necessary to change it (or clean it) more often. This procedure may be done by user or service technician, providing a record is kept of each replacement or cleaning date to assure an established diligent routine.

Slant/Fin KC-90, KC-45 manual Taking Care Your Boiler

KC-45, KC-90 specifications

The Slant/Fin KC-90 and KC-45 are innovative and highly efficient commercial boilers designed to meet the heating demands of various applications. Known for their advanced engineering and reliability, these units specialize in delivering optimal performance while ensuring energy efficiency and environmental compliance.

One of the standout features of the KC-90 and KC-45 models is their unique design, which incorporates high-efficiency cast iron heat exchangers. This design promotes maximum heat transfer, ensuring that more of the energy consumed is converted into usable heat for a building or industrial application. The cast iron construction also contributes to the durability of the units, allowing them to operate efficiently over an extended lifespan.

Both models are equipped with powerful burners that can accommodate a range of fuel types, including natural gas and propane. This flexibility makes them suitable for a variety of installation scenarios. The burners are designed for easy maintenance, allowing technicians to perform service tasks without significant downtime, thereby improving the overall reliability of the heating system.

In terms of technology, the KC-90 and KC-45 feature integrated electronic controls that enable precise temperature management. These controls allow users to set and maintain desired settings, optimizing energy consumption and leading to cost savings on utility bills. Additionally, the advanced controls can often be integrated with building management systems, offering further capabilities for monitoring and automation.

These boilers also prioritize environmental sustainability. With low NOx emissions, they comply with strict regulatory standards, making them an eco-friendly option for heating large spaces. Their efficient operation not only reduces greenhouse gas emissions but also minimizes the overall carbon footprint of the heating system.

Furthermore, the KC series is designed with user-friendly features, such as convenient access panels for troubleshooting and routine maintenance. This attention to serviceability helps ensure that the systems remain operational and efficient, even in demanding environments.

In conclusion, the Slant/Fin KC-90 and KC-45 boilers exemplify top-tier engineering and technological innovation. With their high-efficiency heat exchangers, flexible fuel options, advanced electronic controls, and commitment to environmental standards, these models are ideal for commercial and industrial heating applications, providing reliable and efficient heating solutions for years to come.
