This product must be used in accordance to the following directions by HVACR professionals only.
For proper treatment, it is necessary to initially charge the boiler with one gallon of Ty-Ion B14A for every 250 gallons of water in the system. However, to avoid the potential for surging when filling the boiler, add 1/2 gallon (in the case of cast iron boilers, use 1/4 gallon) for each 250 gallons of water. If the capacity is unknown, refer to the BTU/Capacity chart below for an estimation or calculate the volume of water. Allow boiler to operate two weeks to one month before adding balance of the product. Use W003-0 Nitrite Test Kit and test the nitrite (NaNO2) level in the boiler water to determine the amount of product that is present. Gradually add enough product to bring the ppm(mg/L) of nitrite in the boiler to 1000. At this point, the color of the system water in the sight glass should match the color standard of the B14A Comparator available from Nu-Calgon Wholesaler, Inc. Please note that additions of the product to reach 1000 ppm should be done over a period of several weeks to avoid possible surging.
