can result in substantial property damage.
• DO NOT use "homemade cures" or "boiler patent medicines".
Serious damage to boiler, personnel and/or property may result.
• Continual fresh makeup water will reduce boiler life. Mineral buildup in boiler heat exchanger reduces heat transfer, overheats the metal,
and causes heat exchanger failure. Addition of oxygen can cause internal
corrosion in system components. Leaks in boiler or piping must be
repaired at once to prevent makeup water.
