57Start-Up PreparationCheck and Test AntifreezeFor boiler systems containing antifreeze solu-tions, follow the antifreeze manufacturer’sinstructions in verifying the inhibitor level andto ensure the fluid characteristics are withinspecification requirements.Due to the degradation of inhibitors over time,antifreeze fluids must be periodically replaced.Refer to the manufacturer of the antifreeze foradditional instructions.Use of Antifreeze in the Boiler SystemNEVER use automotive or ethylene glycolantifreeze or undiluted antifreeze in theprimary system as freeze protection. Thiscan cause severe personal injury, death orsubstantial property damage if ignored.Determine the antifreeze fluid quantity usingthe system water content volume and followingthe antifreeze manufacturer instructions.The water volume of the PRESTIGE Solo isapproximately 3 gallons [12 L] for PRESTIGESolo 60 or 5 gallons [19 L] for PRESTIGE Solo175/250 or 7 gallons [26 L] for PRESTIGE Solo399 . Remember to include the volume of theexpansion tank.Check with local codes requirements for theinstallation of backflow preventers or actualdisconnection from the boiler’s cold water fillor make up water supply line.Massachusetts Code requires the instal-lation of a backflow preventer ifantifreeze is used.Ensure the concentration of antifreeze to waterdoes not exceed a 50/50 ratio.System fluid including additives, must bepractically non-toxic, having a toxicityrating or Class of 1, as listed in ClinicalToxicology of Commercial Products.Filling the Boiler System1. Close the boiler drain valve located on thebottom of the unit and any manual or auto-matic air vent in the system.2. Open all system isolation valves.3. Fill the boiler system to correct systempressure. Correct pressure will vary witheach application.Typical residential system fill pressure is12 psi. System pressure will increasewhen system temperature increases.Operating pressure of the system shouldnever exceed 25 psi.4. Purge air and sediment in each zone of theboiler system through the purge valve.Open air vents to allow air to be purged inthe zones.5. Once the system is completely filled andpurged of all air and sediment, check thesystem pressure and check/repair any leaks.Unrepaired system leaks will cause con-tinual makeup water to be added to theboiler. Continual makeup water willcause mineral buildup within the heatexchanger, reducing the heat transfer,causing possible heat buildup and even-tual heat exchanger failure.NOTICENOTICEWARNINGNOTICEWARNING
