6.Considerations of warranty should the boiler system be used for temporary heat without adherence to the recommended start-up and operating procedures outlined in the instruction manuals.

3.2CLEANING THE BOILER AND SYSTEM – NEW SYSTEMS

BOIL OUT PROCEDURE

The internal surfaces of a newly installed boiler will have oil, grease, or other protective coatings used in manufacturing. Such coatings must be removed since these coatings lower the heat transfer rate and reduce operating efficiency. The operator must be familiar with the procedure outlined in the boiler/burner operating instruction manuals.

In combination with system contamination, bacteria may cause objectionable odors, sometimes resembling natural gas. It is important to keep these fumes from air intake that would distribute them throughout the building. On steam humidification systems this is especially critical. Consult your local water treatment chemist for further information. Your water consultant or water treatment company will be able to recommend a cleaning or boil out procedure.

3.3 SYSTEM CLEAN OUT

Many boilers have been ruined with system contaminants such as pipe dope, cutting oil, metal shavings or chips, and other debris that are left in the piping.

SYSTEM CLEANING PROCEDURE

For steam systems, the boiler will need to be connected to the header utilizing steam to purge the piping and thus push the debris out of the system. However, at this time, all condensate must be wasted until it runs clear and water analysis of the condensate indicates that it is free of contaminants. Steam trap strainers must be periodically opened and cleaned of any debris that accumulates.

During this system clean out, the boiler make-up water must be properly softened and treated. At the conclusion of the system clean out, the condensate must be reconnected.

For existing steam systems, the installation process may have jarred debris loose. Following the boil out of the new boiler, the condensate should be wasted until it is within proper guidelines. Check all steam trap strainers to assure their cleanliness.

3.4REPLACEMENT BOILER INSTALLATIONS: PROTECTION AGAINST CORROSION & SEDIMENT

CLEAN OR REPLACE ALL SYSTEM PIPING AND HEATING UNITS

Arrange for chemical or mechanical cleaning of the entire system. A chemical treatment company should be consulted for the proper means of any chemical cleaning.

Replace any piping considered to be deteriorated beyond safe or cleanable condition.

Flush the system clean, being certain to isolate the boiler.

DO NOT FLUSH THE SYSTEM THROUGH THE BOILER.
