20FlexCore Stainless Steel Condensing Boilers – Installation ManualDOMESTIC WATER SUPPLY PIPINGProper controls must be used to preventwater supplied for domestic use fromexceeding 130°F, 54°C or a scald injury willoccur! When higher water temperatures arerequired for appliances such as a dish-washer, a mixing valve or some othertempering means must be installed.Households with small children may requirewater temperatures less than 120°F, 49°C.Local codes must be complied with!General Piping RequirementsThe FlexCore boiler can be use in combination with anindirect tank to provide hot water for domestic use. Pipingand components must be suitable for use with potablewater. The indirect storage tank must be equipped witha temperature and pressure relief valve that complieswith ANSI Z21.22 or CAN-4.4 and CAN-4.6.The storage tank must be located as closeto the boiler as possible to prevent excessivehead loss which will reduce flow.Expansion TankAn expansion tank or other means to control thermalexpansion must be installed in the water heating systemif back flow prevention devices are installed.Two typical water heating systems are shown in Figures14 & 15.Thermostatic Mixing Valve- Water Above 140°F, 60°CWater can be stored a temperatures above 140°F,60°C provided that a thermostatically controlled mixingvalve is used to temper the hot water to an acceptabletemperature before it's supplied for domestic use. Themixing valve MUST be set to prevent a scald injury fromoccurring, see the caution against scalding above.Storage of water for domestic use above 140°F, 60°Cwill provide an increased quantity of tempered water andhelp prevent the growth of water born bacteria.Figure 14 - Typical Single Boiler with Indirect Storage Tank PipingRIOM-0206_AHEAT NETSENSOREXPANSIONTANKTHERMOMETERBACKFLOW PREVENTIONDEVICEGATE VALVEPUMP TEMPERATURE &PRESSURERELIEF VALVEPRESSURERELIEF VALVECHECK VALVE VACUUM RELIEFVALVENOTES:1.
