MACH® Series Gas-Fired Boiler

untreated make-up water will cause premature failure due to buildup of scale; such failure is not covered by warranty.

Scale can also reduce efficiency. For example, a scale thickness of 1/16" will result in a 12.5% loss of efficiency.

Water pH

The pH of the hydronic system fluid must be between

6.0and 8.5. A periodic check of the system pH should be conducted to ensure these pH levels are maintained.

IMPORTANT!

Glycol and other additives must be approved by the chemical manufacturer for use in aluminum boilers and must meet the required pH levels listed above to prevent damaging the boiler.

The water quality should be within the guidelines established by the American Boiler Manufacturers Association, as follows:

Total solids:

2,500 ppm

Total hardness:

150 ppm

The amount of oils, fats, grease, and other organic matter should be limited to 10 ppm.

Consult your water conditioning or chemical treatment supplier for analysis and recommendations.

Flushing the System

Before filling the boiler, flush the system to remove any debris from construction or maintenance. Clean and flush old piping thoroughly before installing the boiler.

IMPORTANT!

Under no circumstances should the hydronic system be flushed while the boiler is attached to the system since the debris or corrosion products could accumulate in the boiler and plug the boiler heat exchanger.

Installation

IMPORTANT!

If the piping system attached to this unit will be chemically cleaned, the boiler must be disconnected from the system and a bypass installed so that the chemical cleaning solution does not circulate through the boiler. Following chemical cleaning, the system should be thoroughly rinsed to remove cleaning agents prior to reconnecting the boiler to the system.

Filling

To be sure that the boiler is not air-bound, open the pressure-relief valve located at the rear of the boiler. Leave the relief valve open until a steady flow of water is observed. Close the valve and finish filling the system.

3.9BURNER AND IGNITION SYSTEM

3.9.1 Inspection

Inspect the unit to be sure nothing was damaged or knocked loose during shipment. Since some damage may be hidden, remove the top cover and inspect the boiler.

Inspect the gas train, blower, ignition electrode and boiler in general to be sure there was no damage during shipment or installation.

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.
