Sludge Conditioner, 1 Gallon, PKG QTY (2)

Reduces mineral deposits in boiler side of water-to-water heat exchangers. See Owner’s Manual or 4200 Parts Book for amounts to use for each model. NOTE: Sludge Conditioner should be used if the water quality is known to contain higher concentrations of minerals or solids. It is best to use softened water instead. If a furnace has been subjected to low Corrosion Inhibitor levels and corrosion is evident in the water jacket, Sludge Conditioner can be used to help clean some of the corrosion from inside the water jacket before flushing and refilling.
