The MACH C1500H/C2000H/C2500/C3000/C4000 gas fired boilers are fully modulating using variable speed
combustion blowers, sophisticated microprocessor controls, modulating gas safety shut off / control valves and a
unique aluminum alloy heat exchanger capable of operating in a fully condensing mode to provide maximum
efficiency in a minimum amount of space. The high quality materials and thoroughly tested design of the boiler should
provide years of trouble free service if the instructions in this manual are followed carefully.
This manual covers the installation of MACH
fuel (natural gas and propane) boilers. The model number may be followed by a prefix or suffix letter in some cases to
indicate special features or different options.
While details may differ slightly, basic operation is the same for all models. Check the rating plate for correct fuel
usage and gas pressures.
The boiler is only a part of the complete heating system. This boiler may be fully operational and yet because of poor
circulation, control, or other operating characteristics not deliver heat to the desired location. Additional equipment
such as temperature sensors, pumps, flow switches, balancing valves, and check valves will be required for
satisfactory operation of any system. Harsco Industrial, Patterson-Kelley cannot be responsible for the design or
operation of such systems and a qualified engineer or contractor must be consulted.
