Gas Fired Boiler Technical Service 1.877.728.5351 Appendix C – Water Quality Standards Quality Standards for Hydronic Boilers in Multi-Metal Systems Patterson-Kelley boilers are designed to be incorporated into any multi-metal hydronic heating system. All multi- metal hydronic systems require that attention be paid to water treatment.
NOTE: This strainer is not intended to remove fine particulate matter from the boiler system which will be discussed later in this appendix. 4. Patterson-Kelley recommends installing a water meter on the cold water fill piping. The intention of this device is to periodically monitor the amount of fresh water introduced into the system piping.

(blended) sample. 11. Within the first three months after startup, Patterson-Kelley recommends collecting a follow-up water sample from the hydronic system. This should be compared to the initial startup sample in order to determine any changes in pH, Alkalinity, conductivity, etc.
Maximum Inlet Pressure = 14.0” W.C. Maximum Inlet Pressure = 14.0” W.C. NOTE Patterson-Kelley recommends installing an individual lock-up type gas regulator in the gas supply piping to each boiler. For installations where one master lock-up type gas pressure regulator will service multiple...

The chart below represents the pressure drop (Ft of Head) versus the water flow rate (GPM) for the MACH C-1500H & C-2000H. This information is useful to help size an appropriate circulation pump. Keep in mind this pressure drop represents the boiler only, additional consideration is needed for any connected piping, valves, strainers, couplings, flanges, etc.
