Boiler PipingSystem Piping - Zone ValvesConnect the PRESTIGE Solo to the systempiping as shown in Fig. 10 page 21 when zoningwith zone valves. The primary / secondarypiping ensures that the boiler loop has sufficientflow.NOTICETo ensure adequate flow rate throughthe PRESTIGE Solo, maintain a minimum1 inch diameter on the system pipingconnecting to the boiler.System Piping - Through BoilerIn new or retrofit applications, in which primary/secondarypiping is not utilized and the systemis zoned with zone valves, a circulatorcould pump through the boiler and systemdirectly. When pumping through with morethan one zone, a pressure differential bypassvalve is required to avoid dead heading thepump through the post pump feature of thecontrol. Consult Fig. 11 and 12 page 22 forpiping diagrams and Graph 2 on page 72 forproper circulator sizing.System Piping - Radiant HeatingThe heat exchanger design of the PRESTIGESolo allows operation in a condensing mode.This feature requires no regulation of the returnwater-temperature back to the boiler in radiantheating applications.The boiler water supply temperature can bemaintained by the PRESTIGE Solo, eliminatingthe need for a mix system to achieve thedesired temperature.It is recommended for the installer to add ahigh temperature limit as shown in Fig. 13page 23. This will ensure that the primary supplytemperature does not exceed the maximumallowable temperature for the radiant tubing.BEST PRACTICEThe addition of the high temperaturelimit is important if the PRESTIGESolo is connected to a domestic hot watersystem, which requires a high primarysupply water temperature.Size the system piping and circulator to providethe flow needed for the radiant system.NOTICETo ensure adequate flow rate throughthe PRESTIGE Solo, maintain a minimum1 inch diameter on the system pipingconnecting to the boiler.System Piping - Special ApplicationIf the boiler is used in conjunction with achilled water/medium system, the boiler andchiller must be piped in parallel. Installflow/check valves to prevent the chilled mediumfrom entering into the boiler.If the boiler is used to supply hot water to theheating coils of an air handler where they maybe exposed to chilled air circulation, installflow/check valves or other automatic meansto prevent gravity circulation of the boilerwater during cooling cycles.System Piping - Multiple Units InstallationUse a balanced manifold system as the primary/ secondary connection to the spaceheating piping as shown in Fig. 14 page 24.Maintain a minimum of 6 inches [153 mm] ofclearance between units to allow for servicing.Refer to Figs. 6 and 7 page 18 to install air separatorand expansion tank.For the space heating piping refer to the applicationsmentioned in this manual or use recognizeddesign methods.19
