MACH® Series Gas-Fired Boiler

5.1.4 Semi-Annually (every 6 months)

In addition to the recommended monthly service:

1.Clean burner of any accumulated dust or lint. See Section 5.2 on "Cleaning the Burner."

2.Inspect burner for any signs of deterioration or corrosion. Replace immediately if deterioration or corrosion is evident.

Installation and service must be performed by a qualified installer or service agency who has been trained on the Patterson-Kelley MACH boiler.

The blower motor is permanently lubricated and does not require periodic lubrication.

5.1.5 Annually

In addition to the recommended monthly service:

1.Inspect and clean the inlet screen of any accumulated dust or lint.

2.Check burner and clean off any soot or foreign material that may have accumulated. See Section 5.2 on "Cleaning the Burner." Check for corrosion of the burner and its parts. If there is evidence of deterioration or corrosion, replace immediately.

3.Inspect combustion chamber when the burner is removed for inspection. Note any signs of deterioration. Clean as necessary.

4.Inspect and clean heat exchanger. Use vacuum to remove accumulations from the heat exchanger pins and surfaces. Clean the casting pins by flushing with clean water and air drying. Do not use any cleaning agents or solvents. A soft nylon brush may be used in accessible areas.

5.Drain and flush the inside of the heat exchanger as required (separate from system flush).

6.Examine the venting system at least once a year. Refer to the vent manufacturer's instructions for requirements in addition to those listed below.

a.Check all joints and pipe connections for tightness.

b.Check pipe for corrosion or deterioration. If any piping needs replacing, do so immediately.

Maintenance

7.Qualified service personnel should thoroughly inspect the heating system and correct any problems prior to re-starting the boiler.

8.Perform combustion analysis and readjust to manufacturer's specifications as necessary. It is recommended that a copy of this report is filed for future reference.

9.Perform a leak test of the gas valves in accordance with the manufacturer's instructions.

Installation and service must be performed by a qualified installer or service agency who has been trained on the Patterson-Kelley MACH boiler.

5.2CLEANING THE BURNER

1.Lockout and tagout gas supply to the boiler.

2.Lockout and tagout electrical power to the boiler.

3.Remove the top cover of the boiler.

4.Disconnect the electrical connections to the blower and gas safety shut off / control valves.

5.Unbolt burner hood and remove the gas train assembly.

6.Carefully remove the burner. Use low pressure air to remove any dust or lint from the burner. Using a soft clean cloth, wipe the inside surface of the burner. DO NOT wipe the mesh side (flame side) of the burner.

5.3AFTER ALL REPAIRS OR MAINTENANCE

1.Follow "Pre-Start Check List" (Section 3.10) and all "Safety Checks" (Section 3.11).

2.Check gas pressure. (Section 3.12.2.)

3.Perform combustion check. Adjust gas flow if necessary. (Section 3.12.4.).

MACH-05 specifications

The Patterson-Kelley MACH-05 is an innovative high-efficiency boiler designed to meet the demanding needs of today’s commercial and industrial applications. Known for its remarkable performance and advanced technologies, the MACH-05 stands out in the market with its ability to provide reliable heating solutions while minimizing energy consumption and environmental impact.

One of the key features of the MACH-05 is its cascading capability. This allows multiple units to be linked together for enhanced capacity and redundancy. By operating in a modular system, users can achieve optimal energy efficiency by adjusting the number of active units based on real-time demand. This ensures that the system operates at peak efficiency, increasing overall reliability and reducing operational costs.

The MACH-05 is equipped with a fully modulating burner system, which ensures precise control of output and efficiency across a broad range of operating conditions. This advanced burner technology facilitates a significant reduction in fuel usage compared to traditional fixed-output systems. Combined with its high thermal efficiency rating, the MACH-05 is not only environmentally friendly but also economically advantageous for facilities looking to lower energy expenses.

In terms of construction, the MACH-05 features a compact, lightweight design that allows for easy installation and integration into existing systems. Its stainless steel heat exchanger is built to provide superior durability and resistance to corrosion, ensuring a long operational lifespan and reducing maintenance requirements. This design advantage translates into lower lifecycle costs for end-users.

The boiler also incorporates intelligent control systems that enhance operational efficiency. These controls can monitor and adjust parameters in real-time, optimizing performance and offering detailed diagnostics to anticipate maintenance needs. The user-friendly interface makes it easy for operators to manage the system and access vital information regarding performance metrics.

Additionally, the MACH-05 is designed with safety in mind, featuring multiple safety controls and alarms that function to protect both the equipment and personnel. This commitment to safety ensures that facilities can operate with peace of mind, knowing that they have a reliable and secure heating solution.

In summary, the Patterson-Kelley MACH-05 combines advanced engineering, efficiency, and safety features to provide a versatile and dependable heating solution. Its key advantages, including cascading capabilities, fully modulating burner technology, and intelligent controls make it an ideal choice for commercial and industrial applications, paving the way toward sustainable and cost-effective heating systems.
