Hydronic formula #5 is scientifically formulated to clean and protect boilers and hydronic heating systems. Patented Hydronic #5 will maximize heating efficiency and prolong the useful life of the system.
Shut boiler down, valve off system, remove pressure relief valve. Pour hydronic #5 into opening, replace valve, open lines, then fire boiler normally. To complete job without shutting system down, mix HYDRONIC #5 in a pail with water, inject directly into boiler draw-off with a SILVER KING ALL BRASS FORCE AND SUCTION PUMP.
Use one quart for each 110,000 BTU's of boiler rating. For best results, use once each year.
