Condensing High Efficiency Stainless SteelSeries Gas Boiler

Make the right move.When it comes to heating your home, it’s important to choose a de-pendable boiler that will give you optimum fuel savings. The CHSboiler offers eight different sized models to match the heating require-ments of the home. These boilers are modulating, condensing, stain-less steel, wall mount boilers. With sizes ranging from85,000-399,000 Btu/hr inputs and modulation up to 10:1 turndownmaximizes your fuel savings. They offer installation flexibility with op-tions such as topor bottom supplyand return con-nections, top orbottom gas con-nections, ventruns of up to 150ftand five vent ter-mination options.

EfficiencyEngineered to thehighest of standards, the CHS Stainless Steel Fire Tube design HeatExchanger can deliver up to 99% Thermal Efficiency, low-nox emis-sions and a fully modulating burner. It is the clear choice whenchoosing a boiler in today’s “Go Green” focused market.

DependableThe new CHS Boiler is yet another example of Slant/Fin’s goal ofproviding the very best heat exchanger designs and CondensingHigh Efficiency Boiler options to the industry. The CHS series boileris manufactured to the highest industry standards. The ASME certi-fied fire-tube exchanger is constructed of stainless steel for bettercorrosion resistance. Each boiler is factory tested three ways to besure of top performance. The CHS Boiler, combined with Slant/Fin’sindustry leading Customer/ Technical Service departments, resultsin a sure fire winning choice.

The ControlThe Slant/Fin CHSboiler has an advancedHoneywell control thatprovides easy navigationand offers completeauto-diagnostics. All theinformation needed toset up, monitor boilerfunctions and service iseasy to access. Theeasy to use control al-lows for multiple circula-tors and temperaturezones and has an inte-grated cascade featureto join multiple boilers.

• Modbus capability is built in• Built in boiler diagnostics• Built in DHW and space heating control• Shut down based on outdoor temperature• Alarm contacts• Freeze protection

Down-fired Fire TubeThe CHS heat exchangeris ASME certified, burneris down-fired. The tubeshave a dimpled design tooptimize heat transfer,which increases energy ef-ficiency. The Fire Tubesprovide generous spacefor flue gas to pass, andsignificantly reduce theneed for cleaning due tothe vertical configurationand self-cleaning operationwhen in condensing mode.

FlexibilityThe design of the CHSoffers more flexibility thanany other boiler on themarket, with vent runs upto 150', five vent termina-tion options, 2" optionalventing on some modelsand plumbing and gasconnections at either topor bottom.

User InterfaceProvides easy naviga-tion to all of the con-troller’s parameters andsetpoints. The backlitscreen continuously dis-plays system informa-tion to ensure safe andefficient operation.
