    In addition, Patterson-Kelley also recommends the use of motorized combustion air dampers in the combustion air intake ductwork of each individual appliance. When an appliance is offline, its combustion air damper will remain closed which will also help prevent the backflow of flue gases from online appliances.

    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. The chemical additives for any multi-metal system must be specifically formulated for use with all the various metals used in that system.

    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.
  • Page 104 (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. 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 boilers, Patterson-Kelley recommends contacting the local regulator representative for application assistance specifying the appropriate lock-up type regulator and gas pipe sizing.
