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.

HYDRONIC #5

• Prevents formulation of insulating scale on heat transfer surfaces
• Keeps dissolved solids in solution
• Frees and lubricates stuck zone values
• Dissolves insulating sludge on tankless coils
• Prevents corrosion
• Protects and lubricates pump seals and quiets nosy circulators
• Insures maximum heat transfer
• Safe to use in all boilers - contains no petroleum or hazardous components
• Compatible with both ethylene glycol and propylene glycol antifreeze

INSTRUCTIONS

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.
