P-K SONIC® Gas Fired BoilerTechnical Service 1.877.728.5351Revised: June 2, 2017Released: June 2, 2017 HARSCO Industrial, Patterson-Kelley 2017All Rights Reserved.1004905978 P-K SONIC NURO Installation andOwners Manual (Rev F Jun-2017).docxPage 38Condensate DrainThe condensate is acidic (pH between 3.0 and 5.0) and may be corrosive to some building drain systems.A condensate neutralization system may be required and is available from Harsco Industrial, Patterson-Kelley. If the condensate drainage system is exposed to freezing temperatures, it must be field heattraced. The boiler could generate up to one gallon of condensate per 100,000 BTU input. As anexample, an SC-4000 boiler at full fire can produce 40 gallons per hour of condensate. Disposal ofcondensate must comply with all state and local codes.Piping with Refrigeration SystemsWhen installed in a two-pipe system that provides both chilled and hot water, the control system shouldbe configured so as to limit the time rate of change of temperature at the boiler. Consult yourauthorized Harsco Industrial, Patterson-Kelley boiler representative for application guidance.Piping with air handling unitsThe boiler piping system of a hot water heating boiler connected to heating coils located in air handlingunits, where they may be exposed to refrigerated air circulation, must be equipped with flow controlvalves or other automatic means to prevent gravity circulation of the boiler water during the coolingcycle.3.8 Water QualityThe P-K SONIC® boiler’s heat exchanger is made of two different stainless steel alloys. The heatexchanger requires proper water conditions to remain efficient and function properly. Information ofproper water treatment can be found on our website www.harscopk.com type in search: “water quality”.For information, please refer to Harsco Industrial, Patterson-Kelley Multi-Metal Systems Water QualityStandards as it appears in Appendix C – Water Quality Standards Quality Standards for HydronicBoilers in Multi-Metal Systems as this applies to the warranty of your heat exchanger. Under nocircumstances should Soften Water be used in boiler.If the piping system attached to this unit will be chemically cleaned, the boiler must be disconnectedfrom the system and a bypass installed so that the chemical cleaning solution does not circulatethrough the boiler. Following chemical cleaning, the system should be thoroughly rinsed to removecleaning agents prior to reconnecting the boiler to the system.NOTICE! The chemical manufacturer for use must certify glycol or other treatment chemicalsadded to the system in multi-metal systems that include a copper heat exchanger.Under no circumstances should petroleum based cleaning or sealing compounds be used in theboiler system.Under no circumstances should the hydronic system be flushed while the appliance is attached tothe system since the debris or corrosion products may accumulate in the appliance and obstruct theappliance’s heat exchanger.
