WTRTRTHEATSYS-M Water Treatment for Heating Systems - Monthly

Application:                                                Man Hours 2

This is applicable to boilers and both steam and hot water distribution and
return systems.  Note:  This maintenance guide does not eliminate daily testing
where it is an established policy.

Special Instructions:

1.  Chemicals must comply with the Environmental Protection Agency (EPA)
    regulations and handled in accordance with occupational safety requirements.
    Employ personal protection against corrosive or hazardous treatment chemicals
    as appropriate.
2.  Be familiar with the Material Safety Data Sheets of any chemicals used in the
    water treatment program.
3.  Water treatment specialists must be properly trained.
4.  Water treatment must be based on proven standard engineering practices.
    Treatment methods that claim mysterious magnetic or catalytic forces shall
    not be used.  Follow treatment methods as directed by the manufacturer or
    water treatment company.
5.  Maintenance includes chemicals, chemical feeding, maintaining proper water
    conditions, controlling blow down, protecting idle equipment, and records.
6.  Select water treatment methods which protect the life of equipment, maximize
    heat transfer, and minimize scale, corrosion, solid matter buildup,
    biological growth, and water usage.
7.  Ensure chemicals are properly stored, test equipment clean, and that
    chemicals have not passed expiration date.
8.  Special attention must be paid to infrequently used boilers, or boilers
    subjected to long periods of idleness.
9.  Physical inspections of boilers and supply and return piping systems are to
    be made to determine water treatment effectiveness.
10. Maintain records and test results.
11. Follow the Recommended Rules for Care and Operation of Heating (or Power)
    Boilers as contained in the American Society of Mechanical Engineers.
12. When boilers are out of service, they must be protected from corrosion either
    by draining the boiler and keeping surfaces thoroughly dry or by completely
    filling the boiler with properly tested with water.

Items to Check & Initial Completion:

1.___ Inspect boiler and piping system to determine effectiveness of water
2.___ Test each system for proper pH, alkalinity, total dissolved, hardness,
      conductivity, scale and corrosion inhibitors, and sludge conditioners.
      Test supply water for base conditions.
3.___ Add or adjust chemical and biological treatment dosages and water blow down
      as appropriate.
4.___ If make up is excessive, determine source of leaks and correct.
5.___ Record test results, action taken, type of chemicals, and treatment
      quantities used.
6.___ If treatment is not effective, it may require change in current methods and
