Boiler PipingSystem Piping - Through BoilerIn new or retrofit applications in whichprimary/secondary arrangement is not utilized, thePRESTIGE Solo allows this flexibility due to alower boiler pressure drop, see Graphs 2 through7 on pages 91 through 93.Figure 11, page 22 illustrates a multiple zonevalve system with a single system/boiler circulator.A by-pass loop with a pressure differentialvalve must be installed on the system piping.Figure 12, page 22 illustrates a single zone utilizingthe boiler circulator as the system circulator.System Piping - Radiant HeatingThe heat exchanger design of the PRESTIGEallows operation in a condensing mode. Thisfeature requires no regulation of the returntemperature back to the boiler in radiant heatingapplications.The design and construction of the PRESTIGEheat exchanger allows the installation of the boileron systems with non - oxygen barrier tubing.CAUTIONDO NOT install a SMART tank alongwith the PRESTIGE in systems withnon-oxygen barrier tubing. Failure tocomply could result in premature failureof the SMART tank.The boiler water supply temperature can bemaintained by the PRESTIGE, eliminatingthe need for a mix system to achieve thedesired temperature.It is recommended for the installer to a hightemperature limit to ensure that the primarysupply temperature does not exceed the maximumallowable temperature for the radianttubing.Size the system piping and circulator to providethe flow needed for the radiant system.NOTICETo ensure an adequate flow rate throughthe PRESTIGE Solo, the boiler supplyand return piping size must be a minimumof 1 inch for the PRESTIGE Solo 60,1-1/4 inch for the PRESTIGE Solo175/250 and 1-1/2 inch for the PRESTIGESolo 399.NOTICEThe addition of the high temperature limitis important if the PRESTIGE is connectedto a domestic hot water system, whichrequires a high primary supply watertemperature.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 space heatingpiping as shown in Fig. 13 page 23.Maintain a minimum of 6 inches [153 mm] ofclearance between units to allow for servicing.Refer to Figs. 7 and 8 page 19 to install air separatorand expansion tank.For the space heating piping refer to the applicationsmentioned in this manual or use recognizeddesign methods.20
